[Botany • 2015] Aristolochia phuphathanaphongiana • A New Species of Aristolochia (Aristolochiaceae) from southwestern Thailand

Aristolochia phuphathanaphongiana Do sp. nov. from southwestern Thailand is described here. The new species is most similar to A. acuminata and A. kongkandae, but it is distinguished by having a broad-ovate to cordate bracteole that is sessile and 8–15 × 6–12 mm, the entire perianth being dark purple to maroon black, with lanceolate limb and abaxial surface densely covered with long grey hairs, as well as by non-winged seeds. In addition to the description, a key to the species of Aristolochia subsect. Podanthemum from the Himalayan region and Indochina is provided.
