FLORA OF NEPAL NOTULAE V: NEW SPECIES AND COMBINATIONS IN HIMALAYAN PLANTAGINACEAE AND SCROPHULARIACEAE
type: item
description: Two new species in the genus Lagotis Gaertn. (Plantaginaceae) are described from Nepal. Specimens of Lagotis annupurnensis and L. geniculiflora were formerly identified as belonging to the polymorphic species L. kunawurensis. They are distinguished from this species by their geniculate or bent corollas. Lagotis annapurnensis and L. geniculiflora are distinguished from each other by the size and shape of their bracts. A key to the species in Nepal is provided. Two combinations are made in Nanorrhinum (Plantaginaceae), and two combinations in Scrophularia (Scrophulariaceae), to reflect changes in the taxonomy of Kickxia Blume and Oreosolen Hook.f.

CONNATE OVARIES AND MULTIPLE FRUITS IN RUBIACEAE, WITH REDUCTION OF CONJUGATOVARIUM TO SYNONYMY WITH MITCHELLA (RUBIACEAE – MITCHELLEAE)
type: item
description: Multiple fruits are rare in Rubiaceae, occurring in only 14 genera. They have evolved in different ways in phylogenetically distant clades. We present a survey of all known occurrences of multiple fruits in the family. Leaving aside the poorly known genus Pagameopsis, we distinguish four types: (i) double or multiple drupes resulting from fusion of neighbouring ovaries Prismatomerideae, Mitchelleae and Morindeae), (ii) dry fruits resulting from partial fusion of a flower pair (Calanda in Knoxieae), (iii) dry multiple fruits dehiscing by an operculum (Anthospermeae – Operculariinae), and (iv) massive fleshy, woody or fibrous globose multiple fruits formed by expansion of the inflorescence tissue embedding numerous ovaries (Naucleeae). Based on this framework, we evaluated the systematic position of the Taiwanese genus Conjugatovarium, characterised by paired flowers with connate ovaries. Comparison of the characters excludes affinity with most lineages possessing multiple fruits due to major differences in habit, floral and fruit morphology, and biogeography. However, Conjugatovarium lalashanianum matches Mitchella undulata in all morphological characters, and both taxa co-occur in northern Taiwan. We formally place Conjugatovarium in synonymy with Mitchella and treat C. lalashanianum as M. undulata.

ADENOSCIADIUM OMANENSIS (APIACEAE), A NEW SPECIES FROM THE NORTHERN MOUNTAINS OF OMAN
type: item
description: Adenosciadium omanensis, a species new to science, is described from the foothills of the northern mountains of Oman. It is closely related to Adenosciadium arabicum but differs in having a reniform leaflet with finely serrate margin, a compact inflorescence, lanceolate bracts and bracteoles with acute tip, a cylindrical fruit (schizocarp) with narrow commissure, oblong-oval terete mericarps with an exocarp covered with long forked hairs, and an emarginate endocarp on the commissural side. Adenosciadium omanensis is illustrated by photographs in its natural habitat. In addition, a comparative morphological analysis is presented that distinguishes it from Adenosciadium arabicum, the single species known in the genus, from southern Oman and Yemen. A distribution map for the two species in Oman is provided.

A REVISED CONSPECTUS OF SARCOTHECA (OXALIDACEAE)
type: item
description: A synopsis of the Southeast Asian genus Sarcotheca (Oxalidaceae) is presented. The number of species recognised has increased from 11 in the last revision of the genus to 15, primarily due to the elevation of Sarcotheca laxa varieties to species rank. The first validation of the basionyms for three species has been changed, as the generic name Connaropsis was not validly published in the generally cited source. A lectotype is designated for Connaropsis, and seven species names are lectotypified, two of them at the second step. Additionally, Sarcotheca laxa is confirmed as part of Thailand’s native flora.

GAULTHERIA ROSTRATA (SECT. DIPLYCOSIA, ERICACEAE), A NEW WINTERGREEN SPECIES ENDEMIC TO MINDANAO ISLAND, PHILIPPINES
type: item
description: Gaultheria rostrata, a new species of wintergreen endemic to Mindanao Island, Philippines, is here described and illustrated. It resembles Gaultheria bartolomei, endemic to Luzon Island, but differs by having a terrestrial habit, shorter petioles, longer pedicels, white or pale-pink corollas, coiled corolla lobes, longer anther tubules, and a longer style. The flowers of Gaultheria rostrata are unique among Asian species of Gaultheria on account of their coiled corolla lobes exposing the anthers and style at anthesis. This discovery raises the number of Gaultheria species in the Philippines to 16.

BEGONIA MATILLANOAE (BEGONIACEAE), A NEW SPECIES FROM MALAMPAYA SOUND PROTECTED LANDSCAPE AND SEASCAPE, PALAWAN ISLAND, PHILIPPINES
type: item
description: A new species, Begonia matillanoae, is here described and illustrated from Malampaya Sound Protected Landscape and Seascape, Palawan Island, Philippines. It closely resembles Begonia cabanillasii but is distinct in having an ovate leaf with irregularly lobed margin, an acute leaf apex, and a 5-tepalled pistillate flower with the larger wing flat to shallowly cucullate. Begonia matillanoae is the latest addition to the Palawan begonias bearing a conspicuously 5-winged ovary. Based on IUCN guidelines, we here propose a Critically Endangered (CR) conservation designation for this species. A revised key to Palawan Begonia sect. Baryandra bearing five or six conspicuous ovary wings is also provided.

ELAEOCARPUS PULNEYENSIS, A NEW SPECIES OF ELAEOCARPUS (ELAEOCARPACEAE) FROM PENINSULAR INDIA, BASED ON MORPHOLOGICAL AND MOLECULAR EVIDENCE
type: item
description: A new species of Elaeocarpus is described from the Kodaikanal region of Pulney Hills, India; it is morphologically allied to E. variabilis in having anther tips without setae or tuft of hairs and 3-locular pyrenes. It differs from the latter in having ovate, light-green sepals, and ellipsoid fruits enclosing ellipsoid pyrenes. Molecular phylogenetic analyses based on ITS and trnL–F regions revealed that Elaeocarpus pulneyensis is distinct from E. variabilis and support the novelty of the taxon.

GENTIANA MACNEILLIANA (GENTIANACEAE), A NEW SPECIES FROM SIKKIM HIMALAYA (INDIA) BASED ON MORPHOLOGICAL AND MOLECULAR DATA
type: item
description: Gentiana macneilliana (Gentianaceae), a new species from North Sikkim, in the Eastern Himalayan region of India, is described, illustrated and discussed. It is morphologically similar to Gentiana lacinulata T.N.Ho of Gentiana sect. Chondrophyllae Bunge but differs markedly in having acute and usually mucronate leaf apex, ovate corolla lobes with acuminate apex, much longer plicae (1.5–2.6 mm), which are more than half as long as corolla lobes, and longer pedicel (up to 8 mm). This new species also resembles Gentiana muscicola C.Marquand (Gentiana sect. Chondrophyllae) but can easily be differentiated by its unique corolla lobe, shorter petiole, narrowly based leaf lamina, longer pedicel and shorter style. The affinity of the new species with Gentiana grata Harry Sm., a member of the same section, is also highlighted. A taxonomic description, images and illustrations of the new taxon are provided, along with a discussion of closely related taxa.

THE IDENTITY AND TYPIFICATION OF THE BEGONIAS FROM VELLOZO’S FLORA FLUMINENSIS
type: item
description: We review the 22 names in the genus Begonia (Begoniaceae) from J. M. da C. Vellozo’s Flora Fluminensis, taking advantage of recent advances in the understanding of Vellozo’s collecting itinerary and the Begonia flora of southern Rio de Janeiro State, Brazil. We unambiguously match 18 of Vellozo’s names to current species concepts in the genus Begonia, resulting in 10 new synonyms. We provide lectotypifications and epitypifications and accepted names for all taxa. The widespread and common species currently known as Begonia radicans Vell. is shown to be a misapplication of the name, and we reinstate the name B. limmingheiana É.Morren for this taxon. We report the rediscovery of Begonia acetosa Vell., which was last collected approximately 250 years ago by Vellozo, and provide an emended description and IUCN conservation assessment for this species. We are unable to match four of Vellozo’s names to current species concepts and propose that they are rejected.

TYPES IN HERBARIUM AMBOINENSE: THE NAMES OF VASCULARPLANTS TYPIFIED BY ILLUSTRATIONS IN THE PUBLICATION OF RUMPHIUS
type: item
description: A list is presented of more than 300 names of vascular plants that are typified by illustrations published in Herbarium Amboinense, the botanical magnum opus of Rumphius. The list includes the currently accepted name for each entry and its typification, where available. Merrill effectively designated lectotypes for some two-thirds of the names linked to Herbarium Amboinense; the rest were dealt with by various authors. In total, 85 new typifications are presented, including both lectotypes and epitypes. A new combination in Ochrosia (Apocynaceae) is proposed. Some nomenclatural issues relating to names published by Loureiro in Flora Cochinchinensis, for which no extant specimens are available but which could be typified by Rumphius illustrations, are also highlighted.

TRANSFER OF THE GENUS AULANDRA INTO PALAQUIUM (SAPOTACEAE) AND ASSOCIATED NOMENCLATURAL CHANGES
type: item
description: Aulandra H.J.Lam (Sapotaceae) has hitherto been treated as a genus of tropical forest trees native to Borneo. To test whether the genus is distinct from Palaquium Blanco, phylogenetic analysis using maximum likelihood was performed on target capture of nuclear data, including all species currently recognised as belonging in Aulandra. The results confirm that Aulandra is nested within Palaquium and should be synonymised with it. One new combination, Palaquium longifolium (H.J.Lam) A.Phang, is made, and the application of the name P. beccarii discussed, resulting in the description of a new species, Palaquium aulandrum A.Phang.

THE PUTRANJIVACEAE OF THE WORLD: A CROSS-REFERENCED CHECKLIST OF THE GENERA AND SPECIES
type: item
description: An updated taxonomic checklist of all the accepted species and infraspecific taxa of the family Putranjivaceae (Malpighiales) worldwide is presented. We currently accept 223 species in two genera, Putranjiva (four species) and Drypetes (219 species). A morphological description of the family and a nomenclatural checklist of its infrageneric taxa and species are provided, and for each species the correct name, synonyms and type information, as well as available information on distribution, habitat, published iconography and infrageneric classification are given. To stabilise the nomenclature of the Putranjivaceae, a total of 133 lectotypes and five neotypes are designated, as well as a new combination, Putranjiva sect. Matsumuranae (Hurus.) Quintanar, Barberá & D.J.Harris comb. nov. Type species for four sectional names (Drypetes sect. Oligandrae, Drypetes sect. Roxburghianae, Drypetes sect. Stemonodiscus and Drypetes sect. Stipulares) have been designated, as well as two new species synonyms. The checklist is preceded by an introduction to the family and the taxonomic history of the main taxa. The International Plant Names Index Life Sciences Identifier (LSID) and the World Flora Online Unique Identifier are added to each name, thereby providing direct links to these nomenclatural resources.

PLEUROTHALLIS MARKGRUINII, A NEW PLEUROTHALLIDINAE(ORCHIDACEAE) FROM NORTHWESTERN ECUADOR
type: item
description: Pleurothallis markgruinii, a particularly tall species for the genus, is described as new to science and an illustration provided. The new species is most similar to Pleurothallis gargantua and shares with that species its large size, reaching 1 m tall, but differs in the much smaller flowers with a deeply concave dorsal sepal, narrower petals, and a synsepal with strongly revolute margins that form an elongated, triangular shape. Comprehensive field research has shown Pleurothallis markgruinii to have a restricted geographical range in the northwest Andes of Ecuador, and it is assessed as Critically Endangered. Pleurothallis markgruinii, una especie con plantas particularmente largas dentro del género se describe e ilustra aquí como nueva para la ciencia. La nueva especie es similar a Pleurothallis gargantua y comparte con esta las grandes plantas que alcanzan 1 m en longitud, pero se diferencia en las flores mucho más pequeñas con el sépalo dorsal muy cóncavo, pétalos más estrechos, y un sinsépalo con márgenes fuertemente revolutos que le dan una forma alargada y triangular. Investigación de campo exhaustiva muestra que Pleurothallis markgruinii tiene una distribución restringida, al noroeste de los Andes en Ecuador y es evaluada como en peligro crítico.

TOPOGRAPHY, CLIMATE AND FOREST COVER DETERMINETHE GLOBAL SPECIES RICHNESS PATTERNS OF FILMY FERNS(HYMENOPHYLLACEAE)
type: item
description: Species richness patterns are essential for understanding how species diversity has evolved. The filmy ferns (Hymenophyllaceae) are one of the largest families of epiphytic ferns; however, a comprehensive global overview of their species diversity and distribution is lacking. In the present study, we identified the regions of greatest species diversity as Central America, South America and Southeast Asia (including Taiwan Island), followed by the Brazilian Atlantic Forest and Madagascar. North America and Europe are low in species richness. Global species richness data based on 100 × 100 km grid cells were analysed to investigate the correlation between species richness and ecological factors. Our results show that filmy ferns have a strong preference for moist and warm habitats, and that current species richness patterns are codetermined by topography, climate and forest cover. Our results also indicate that, as expected, the relationship between soil and epiphytic ferns is minimal, and that there is weak support for the use of solar radiation levels to predict global patterns of diversity for filmy ferns, which primarily occur in deep shade. We highlight potential ecological differences between the two lineages of the Hymenophyllaceae: hymenophylloids and trichomanoids. The unusually low species diversity of filmy ferns in some areas (e.g. the Pan-Himalayan region) is potentially explained by historical ecological adaptation and lack of suitable habitats.

BOURNEA IS NOT SUPPORTED AS SEPARATE FROM OREOCHARIS(GESNERIACEAE)
type: item
description: The genus Bournea Oliv., established in 1893 and comprising two morphologically very similar species with actinomorphic flowers, was included in Oreocharis Benth. in 2011, essentially based on molecular data. However, a recent publication has suggested that Bournea should be maintained as a genus distinct from Oreocharis, based on morphological, palynological and DNA sequence data. By contrast, in another recent publication also based on DNA sequences, Bournea is placed within Oreocharis. The morphological, palynological and published molecular phylogenetic data are discussed here. The conclusion is that the overall evidence available is insufficient to support an independent genus, Bournea.

SKOGEA IS A SYNONYM OF BOEICA (GESNERIACEAE)
type: item
description: The genus Skogea U.B.Deshmukh, a replacement name for the recently described monospecific genus Actinostephanus F.Wen, Y.G.Wei & L.F.Fu and the correct name for the superfluous Radiaticorollarus Y.G.Wei, F.Wen & Lei Cai, is placed in synonymy with the genus Boeica C.B.Clarke. Neither the morphological characters nor the molecular data provide sufficient justification for generic recognition.

TWO HUNDRED YEARS OF BOTANICAL RECORDS: LEGUMINOSAE TREE SPECIES DIVERSITY IN A BRAZILIAN ATLANTIC FOREST HOTSPOT
type: item
description: The Reserva Biológica do Tinguá (REBIO Tinguá) is a protected area in the state of Rio de Janeiro comprising around 26,000 ha of Brazilian Atlantic Forest. We present an updated floristic inventory of Leguminosae tree species in the REBIO Tinguá. Pre-existing herbarium collections and field expeditions carried out in 2021 and 2022 were used as the basis for (i) assembling a comprehensive taxonomically verified checklist of the legumes, (ii) revealing species distribution patterns across the Submontane (‘tingua_s’) and Montane/High Montane Dense Ombrophilous (‘tingua_ma’) Forest physiognomies of the REBIO Tinguá, and (iii) an UPGMA-based floristic similarity analysis to compare the REBIO Tinguá with 28 other areas of Atlantic Forest in Rio de Janeiro state. Of the total 67 legume tree species identified, 35 are endemic to the Atlantic Forest, six are new occurrences for the area, and seven are listed under different threat categories. The legume-based similarity analysis showed clusters that largely reflect the environmental heterogeneity of the region, where ‘tingua_ma’ is grouped with Macaé de Cima, Mendanha and Santo Aleixo, while ‘tingua_s’ is grouped with Paraty Mirim, Pedra Branca, Poço das Antas, Tijuca and REBIO Union. Our study shows that new records can be made for the REBIO Tinguá, despite it being one of the most thoroughly inventoried areas in the state. Our results reinforce the importance of the REBIO Tinguá for biodiversity conservation, because of its great extent, altitudinal amplitude, and above all, its central position in the state, integrating the Mosaico Central Fluminense and the Tinguá–Bocaina biodiversity corridor.

MULTIVARIATE MORPHOMETRIC ANALYSIS OF MANGOSTEEN (GARCINIA MANGOSTANA VAR. MANGOSTANA, CLUSIACEAE) AND ITS WILD RELATIVES
type: item
description: Mangosteen (Garcinia mangostana var. mangostana) is a dioecious and agamospermous cultivated fruit tree. It has two recognised hypothetical wild ancestors, Garcinia mangostana var. malaccensis and G. mangostana var. borneensis, distributed in the lowland dipterocarp-dominated forests of Sumatra, the Malay Peninsula, and Borneo. The highly similar morphological characters between the cultivated and wild varieties have posed challenges in identification. Additionally, Garcinia penangiana is often mistaken for G. mangostana var. malaccensis, and G. venulosa is regarded as morphologically similar to G. mangostana var. borneensis. In the present study, we conducted morphometric analyses of Garcinia mangostana var. mangostana, G. mangostana var. borneensis, G. mangostana var. malaccensis, G. penangiana and G. venulosa. We assessed the efficacy of morphological characters in combination (vegetative–male flowers–female flowers) in distinguishing the taxa as recognised in the current taxonomy. In our morphometric analyses, we found that Garcinia penangiana and G. venulosa are well delimited and congruent with their current taxonomic designations. A combination of vegetative and male-flower characters provided the most definitive delimitation. We recovered the specific coherence of Garcinia mangostana, but the infraspecific delineations of G. mangostana var. mangostana, G. mangostana var. borneensis and G. mangostana var. malaccensis are not supported.
