Miliusa longiflora (Hook.f. & Thomson) Baill. ex Finet & Gagnep.
Miliusa longiflora, newly recorded from Kanchanaburi, Thailand, is described and illustrated.
The genus Miliusa Lesch. consists of ca. 45 species distributed mostly in Asia (Kessler et al. 2000). About 15 species have been recorded for Thailand (Mols and Kessler 2003). The latest newly described species, M. tirunelvelica, was described on material from India by Murugan et al. (2004). The Annonaceae is now under revision for the Flora of Thailand, coordinated by Paul Kessler.
Recently, the first author found M. longiflora during her field work to Bueng Namthip, Thongphaphum National Park, Tumbon Banrai, Kanchanaburi Province in 2003. The description herein is based on this Thai material.
