Abstract
Two new taxa, Caulokaempferia phokhamii Picheans. & Douangde. and C. wongsuwaniae Picheans. & Douangde., from central Lao PDR are described. With C. bracteata K. Larsen & S.S. Larsen and C. bolavenensis Picheans. & Koonterm, a total of four species are currently recognized for Lao PDR. Both new species possess yellow flowers and characteristic labellum with distal median lobe. The hairy pseudostem with reddish–green stripes, hairy ligule, lanceolate leaf blade with reddish brown margin, and the hairy peduncle and bract are characteristic of C. phokhamii. The overall tiny habit, glandular lower leaf surface, and 1(–2) bract(s) subtended (1–)2–3 flowers are unique for C. wongsuwaniae. Full descriptions, together with line–drawings with water–color and photographic illustrations, of the new species are given.
