small, terminal; ovule solitary. Leaves minutely pellucid-punctate. Flowers in long 
terminal peduncles, solitary or.in pairs. Distrib.—Three species; all Malayan. | 
The genus Disepalum was founded by Sir Joseph Hooker on.a Bornean shrub collected 
by Lobb, and the only species known to its founder was that described and figured under 
the name of D. anomalum in the Linnean Transactions (vol. xxiii. 156, t. 20A). The 
characters which separate the. genus from any other in the family are the dimerous 
symmetry of the sepals and petals, and the small size of the latter, which originate at 
some distance from each other from the edge of the broad, sub-concave torus. The 
species here described differs from D. anomalum in its arboreous habit, larger leaves, and 
much more numerous ovaries, which are, moreover, nearly glabrous and have long 
stalks, Quite ripe fruit is as ce unknown.
