Abstract
Hullettia King ex Hook. f. (Moraceae) is newly recorded to the flora of Vietnam. A specimen discovered in the lowland secondary evergreen forest of Song Hinh protection forest, Phu Yen province, central Vietnam was identified as Hullettia dumosa King ex Hook. f. It was earlier known from peninsular Myanmar, peninsular Thailand, peninsular Malaysia, Singapore, and Sumatra. Type material of this species is analyzed, and lectotype is designated (Scortechini s.n., K: K000898664). Photographic illustrations of studied specimens are provided. A key to the Vietnamese genera of Moraceae is presented.
