POUZOLZIA RUGULOSA TRANSFERRED FROM BOEHMERIA, AND THE DISTINCTION BETWEEN BOEHMERIA AND POUZOLZIA (URTICACEAE)

Abstract

Pouzolzia rugulosa (Wedd.) Acharya & Kravtsova, comb. nov., is transferred from the genus Boehmeria on the grounds of the anatomy and morphology of the fruit, correlated with molecular data. A revised set of anatomical and morphological characters is provided to distinguish between Boehmeria and Pouzolzia. Pouzolzia rugulosa shares morphological similarities with a group of serrate-leaved taxa in that genus known from Asia and Oceania. It is a shrub or small tree and is found along the southern slopes of the Himalayas from Himachal Pradesh in northern India to the mountains of northern Burma. It occurs in forest at elevations of up to 1900 m, mainly at forest edges and in clearings. A full description of Pouzolzia rugulosa, including drawings and SEM images of the fruit, is provided, together with a key.
