Revision of Aquifoliaceae, Polygalaceae, Icacinaceae, Hippocrateaceae, Rhamnaceae, Malvaceae, Myrtaceae and Vitaceae has resulted in the following new taxa, new names and new combinations: Polygala sibirica L. subsp. bhutanica Kit Tan, subsp. nov., P. sibirica L. subsp. elegans (Wall, ex Royle) Kit Tan, comb, nov., P. sibirica L. subsp. heyneana (Wall, ex Wight & Arnott) Kit Tan, comb, nov., Zizyphus rubiginosa Long & Rae, sp. nov., Nayariophyton zizyphifolium (Griff.) Long & Miller, comb, nov., Syzygium smalianum (Brandis) Long, comb, nov., and Tetrastigma corymbosum Long, sp. nov.. Notes on some critical Himalayan species of Ilex are provided, new lectotypes are designated for several names, and Salacia membranacea Lawson is shown to be a synonym of S. salacioides (Roxb.) Rao & Hemadri.
