[Botany • 2024] Begonia dakrongensis (Begoniaceae) • A New Species from Dakrong Nature Reserve, Quang Tri Province, Central Vietnam


Begonia dakrongensis C.H. Nguyen, T.A. Le & C.W. Lin,

in Nguyen, Le, Ha et Lin, 2024. 
A new species of Begonia (Begoniaceae), B. dakrongensis, from Central Vietnam is described and illustrated. B. dakrongensis resembles B. abbreviata in its rhizomatous habit, short cymose-paniculate inflorescence with congested bracts, 4-tepaled staminate flowers, and 5-tepaled pistillate flowers. However, the new species markedly differs by having obtriangular-spathulate to oblong-obovate or widely obovate lamina (vs. ovate to broadly ovate), not oblique or nearly so (vs. oblique), widely obovate anthers (vs. narrowly obovate), and trigonous-globose ovary (vs. trigonous-ellipsoid).
