This is closely allied to P. séméarum, Benth. & Hook. fil., but has smaller flowers 
which are often borne on the smaller branches; smaller leaves; and shorter-stalked 
carpels. Moreover the leaves and young branches of this are invariably glabrous. The 
leaves of old trees are very markedly smaller than those on young specimens. Specimens 
in young fruit of a plant which may belong to this species have been recently received 
from the Andamans from the Collectors of the Bot. Garden, Calcutta; but until the 
receipt of fuller material, I hesitate to include these islands in the geographical area 
of the species.

20. PoLyaLTHIA scLEROPHYLLA, Hook. jil. & Thoms. Fl. Br. Ind. 1. 65. A glabrous 
tree; young branches pale. Leaves coriaceous, oblong, ovate or linear-oblong, acute or

reticulations distinct; main nerves about 10 to 12 pairs, spreading, slender; length 6 
to 8 in., breadth 1°5 to 2°6 in.; petiole °5 in. Flowers pedunculate, in fascicles from 
small tubercles on the trunk, 2 in. in diam., greenish; tubercles °5 to 1 in. in diam. ; 
peduncles 1 to 15 in, long, stout, rusty-pubescent, becoming glabrous; bracts small, 
orbicular, from about the middle of the peduncle. Sepals ovate, obtuse, short. Petals 
linear-oblong, obtuse; the base slightly concave, puberulous on both surfaces, 1:6 in.
