 elliptical, apex truncate, emarginate, rounded, or sometimes very shortly 

 acuminate, base wedge-shaped, margin more or less minutely toothed,

 what leathery ; petioles 1-2 cm. 1. Spikes 12-17 cm. 1., peduncle 1-2-5 cm. 1. 

 Bracts truncate, semilunar, without glands. Male flowers several in axil

 ovate-globular. 



We have seen male flowers in bud only, in which there is no union of 

 the filaments ; the seeds also are immature and do not show the " area 

 derasa." The examination of adequate material might prove this species 

 to belong to Sapium.
