Flowers 4 in. long; calyx glabrous. Petals slightly puberulous 
on the outside and ciliate on the edges. Ovary and stylopodium 
puberulous; style very short, glabrous. Fruit enveloped in the 
thinly membranous segments of fruiting-calyx, the larger of 
which are linear-oblong, 24 in. long, 7-nerved with prominent 
transverse veins. Specimens in fruit were received at Kew from 
Mr. Bourdillon.

FI. large, 4 in. long; calyx glabrous. Similar to H. jucunda, 
Thw., but decidedly different. Panicles clustered, 2-4 in one leaf- 
axil; calyx-lobes obtuse, equal. Stylopodium cylindrical, slightly 
narrowed at base, as long as ovary. Style very short. Larger 
segments of fruiting-calyx spathulate, obtuse, with 7-11 longi- 
tudinal nerves. The bark is blackish, peeling off in long recurved 
strips, which hang all round the trunk (Beddome). | 
H. racophloa as well as H. jucunda have hairy glands (domatia) 
in the axils of the secondary nerves. In the case of H. racophlea 
these glands are very large, with one or two round openings at the 
apex.
