18. Mertoporum prismaticom,, Hook, fil. & Thoms. Flora Ind. 121. A large creeper; 
young branches glabrous, dark-coloured. Leaves coriaceous, oblong, elliptic-oblong,. rarely 
obovate-oblong, abruptly and shortly acuminate; the base broad, rounded; . upper 
surface glabrous except the minutely. puberulous midrib; lower surface glaucous, 
reticulate, finely pubescent, especially on the midrib; main nerves 12 to 18 pairs, 
spreading, faint especially near the tip, the secondary nerves prominent; length 4°5

solitary; pedicels -3 to °6 in. long, rufous-tomentose, with 1 large bracteole above 
the middle and several smaller near the base. Sepals quite connate imto a. flat 
obtusely 3-angled disk, °3 in. broad, pubescent outside, glabrous and tubercled inside. 
Petals very thick; the outer linear-lanceolate, 15 to 2 in. long, triquetrous, rufous- 
tomentose outside, puberulous inside; the mner thinner and only about °3 in. long, 
triangular, ridged outside, much excavated and glabrous at the base mside;. otherwise 
puberulous, Stamens numerous, with very short filaments; anthers linear; apex of 
connective obliquely triangular. Ovaries elongate, oblong, tapering to the apex, shortly 
pubescent; ovules about 14, im two rows; style short, lateral; stigma sub-capitate, 
lobulate. Ripe carpels ovoid, blunt, tuberculate, puberulous, becoming sub-glabrous, 
1:4 in. long and °8 in. in diam.; stalks *8 to 1 in., stout. Seeds in two rows,

Authentic specimens both of Pyramidanthe rufa and of Ozymitra bassiefolia, T. and 
B., show that they unmistakably belong to this species. Specimens of the former from 
Bangka and from the Buiteazorg Botanic Garden have, however, their leaves rather 
more hairy beneath than is usual in Perak specimens, and their flowers are also rather 
longer. :
