Abstract

Argyreia decemloba Traiperm, Fujikawa & Staples, a new species of Convolvulaceae from Natma Taung National Park, Chin State, Myanmar, is described here with detailed illustrations and summaries for its distribution, ecology and IUCN conservation status. This new species is a high-climbing twiner that can be distinguished by a white or pale yellow corolla with a deep red or purple-black colour inside at the base of the tube, a ten-lobed corolla limb, and staminal filament bases expanded and densely covered by hispid hairs. Argyreia decemloba is here assessed as Near Threatened (NT) following IUCN Red List categories.

Based on a memorandum of understanding signed by the Kochi Prefectural Makino Botanical Garden, Japan, and the Forest Department of Myanmar, the Makino Botanical Garden and its associated international partner institutions have been conducting plant inventory research since 2000 (Tanaka 2005; Fujikawa 2016), building toward the production of a Flora of Myanmar
Major collecting efforts have been focused on Chin State, Kayin State, Mandalay Region, and southern Shan State, with additional collecting trips made to Kachin State, Mon State, and Sagaing Region
