Abstract

Dysphania geoffreyi is described as a new species, with records in China (Xizang and Yunnan provinces) and Bhutan. It differs from morphologically similar taxa by virtue of the clustered flowers in the inflorescence, indumentum set on the perianth, terminally concave pericarp papillae, and smaller seeds 0.5–0.6 mm in diameter. In total eight native Dysphania species are identified in Himalaya and Tibet, and revised distribution patterns of D. bhutanica, D. himalaica and D. tibetica are presented. The most significant reproductive features of all native Dysphania taxa are summarized.
