Notes
A fairly variable plant. In addition to the yellow-tomentose or velutinous haired typical form as described by SCHEFFER there occur glabrous forms, but in degree, with few hairs, or the hairs still more reduced and confined to the lower part of the petiolar groove, or only to the axillary bud. There are also specimens of which the calyx is inside long pubescent with 1-seriate hairs, notably S11989, 16427, 17591, 25411, SAN 32195, ANDERSON 8398, HALLIER B 2507, VAN NIEL 4019, but they are hairy as the type or glabrous, or with small glabrous leaves, rounded leaves or with short acuminate tip. This is also the reason that I cannot maintain D. coriacea, as the leaf-base varies from cordate to rounded to cuneate, without correlation with other sets of characters. Also the number of crateriform glands varies and these are also found in other specimens. I will not exclude the possibility that in the field certain biotypes may be bound to certain soil types, but I see no possibility to definitions and formal recognition from the herbarium.
In ANDERSON 8398 from Sarawak the leaves are in a whorl of 4.
The Celebes specimens were poor and originally assigned to D. glabra (Steen.) Steen. With abundant recent adequate material from localities nearby, they appear to belong to D. bancana.
Fruits are extremely scarce in the herbarium.
