or 60 feet high; young branches rather stout, puberulous, speedily glabrous and dark- 
coloured, Leaves elliptic to oblong, thinly coriaceous, slightly obovate, shortly caudate- 
acuminate, the base rounded or slightly cuneate ; upper surface shining, quite glabrous; 
the lower puberulous when young, ultimately glabrous ; the main nerves 13 to 15 pairs,

2-75 to 8°75 in.; petiole *3 in. Flowers 2 to 3 m. in Taine solitary or in er 2- to 3- 
flowered racemes, axillary or extra-axillary; pedicels ‘5 to ‘75 in. long with a large 
stem-clasping bracteole near the apex. Sepals spreading or sub-reflexed, ovate, sub-acute, 
slightly connate at the base, puberulous on both surfaces, ‘4 in. long. Pefals thinly 
coriaceous, sub-equal, puberulous, obovate or broadly obovate-lanceolate, blunt, the base 
with a short claw, pale greenish with a blotch of reddish-yellow at the base, all (but 
especially the inner row) more or less convex; the imner row slightly concave and 
elabrous at the base inside. Stamens numerous, cuneate, short; the connective produced.

This species is doubtfully referred to Cyathocalyx by its authors, and chiefly on the 
ground that the petals, although valvate at the base, are slightly imbricate above. An 
examination of the large number of specimens sent from Perak by the Calcutta Botanic 
Garden Collector enables me to state that in bud the petals are truly valvate, but that as 
they develope they undoubtedly overlap. The anthers, ovaries and ripe fruit appear to 
me to be those of Cyathocalyz ; and, in habit, as well as in the general appearance of its 
leaves, this plant agrees with the other species of this genus. In addition to the species 
above described there are, m the Calcutta Herbarium, fruiting specimens from Perak of 
a small tree which is apparently a fourth species of Cyathocalyz. The leaves of this 
are oblong-lanceolate to oblong-ovate, 8- to 10-nerved, glabrous above and puberulous 
beneath; and the ripe carpels are in pairs, ovoid, puberulous, about 1-5 in. long. None 
of the specimens has any trace of flower.
