Disporum cantoniense

Description

Leaves usually ovate, less often oblong or lanceolate, rarely suborbicular, acuminate, 6½-17 by 2.5-9 cm, with 5-9 veins prominent on the lower surface and numerous finer veins; Inflorescence an umbel of 2-7 flowers terminating a short branch which arises opposite a leaf and bears a single sometimes somewhat reduced leaf; Seeds c. 3 mm ø.

Distribution

Asia-Tropical: Jawa (Jawa present); Lesser Sunda Is. (Bali present); Malaya (Peninsular Malaysia present); Sumatera (Sumatera present), Japan present, Pahang present, Perak present, SE. Asia present, northern Deccan Peninsula present, southern China present
SE. Asia from the northern Deccan Peninsula to southern China and Japan; in Malesia: Malay Peninsula (Perak, Pahang) and throughout Sumatra, Java, and Bali.

Notes

Variation in the length of the spur has been used in segregating species, but Backer recognized the continuity of this gradation in Javanese material. Some Javanese plants have spurs as long as those in typical 'D. calcaratum'.
Branching is partly sympodial. Short terminal axes bear the umbel. Continuation of growth of the aerial shoot is by a branch arising in the axil of the second leaf below the umbel. The node separating two leaves associated with the inflorescence is sometimes so short that the leaves appear opposite.
