Dasymaschalon[1] is an Asian genus of bushy plants in the subfamily Annonoideae and tribe Uvarieae. Its native range is from southern China, Indo-China to Malesia (west of the Wallace line).[2]
Morphology
FIGURE 1. Floral morphology in the Dasymaschalon alliance. (A) Monanthotaxis buchananii, showing loosely coherent pollination chamber. (B) Desmos chinensis, with partially closed chamber formed by petals that are basally constricted. (C) Friesodielsia desmoides, with outer petals free spreading, inner petals apically connivent forming a closed pollination chamber. (D) Dasymaschalon dasymaschalum, with three outer petals apically connivent forming a closed pollination chamber. (E) Floral diagram of Friesodielsia. (F) Floral diagram of Dasymaschalon. Colors are used to differentiate floral organs; blue, sepal; green, outer petal; purple, inner petal; gray, stamen; pink, carpel. The ranks and total numbers of stamens and carpels are artificial in (E,F), with six/three lines of stamens and carpels shown at the corners of the hexagonal/triangular floral meristem.[3]
