NEW AND RARE MALAYAN PLANTS. 33 



Polyosma pisocarpa, n. sp. 



Stem pale not angled ; young parts velvety hairy. Leaves 

 stiffly coriaceous elliptic, acute or obovate blunt, nerves fine 

 about 12 pairs very irregular faint on both sides, glabrous ex- 

 cept at first the midrib slightly hairy, 3 — 4 in. long, 1.5 — 1.75 

 in. wide, petiole .5 in. long rather stout sometimes pubescent. 

 Raceme 6 — 7 in. long dense many flowered pubescent. Flowers 

 green, pedicels stout much longer than calyx, hairy. Calyx 

 tube campanulate, lobes triangular acute. Petals .35 in. long 

 sparingly pubescent linear subacute villous inside. Stamens 

 distinctly shorter. Style very slender. Fruit pea-shaped 

 globose, .2 in. long, glabrous " blue " on pedicels slender, gla- 

 brous, .2 in. long. Seed smooth globular. 



Borneo. Sarawak at Kuching and between it and San- 

 tubong (TIaviland, 2911, 2912, 2913, 1464, 1988). 



This species in nearest P. coriacea, King, but it has longer 

 flowers on longer pedicels. The small pea-shaped blue fruit 

 is peculiar. The raceme long and dense. The leaves as 

 Haviland points out are of two forms, in one lanceolate and 

 acuminate, in the other obovate and refuse, but there are more 

 or less intermediate forms on the different specimens and in 

 other respects the plants are the same. 



HAMAMELIDACEAE. 

 Rhodoleia ovalifolia, n. sp. 



A big shrub up to 10 feet tall with thick branches, the 

 young parts densely red-hairy. Leaves, young lanceolate acute 

 base acuminate, older 4 to 6 in. long 1.5 to 2 in. wide, rigidly 

 coriaceous ovate with a rounded subcordate base, apex acute, at 

 first red-scurfy beneath later becoming white-glaucous, nerves 

 strongly elevate 6 — 8 pairs with some of the secondary nerves 

 nearly as strongly elevate both nerves and reticulations de- 

 pressed on the upper surface, 4 — 4.5 in. long, 2.5 in. wide, 

 petiole at first densely velvety, later glabrous. Capitula 

 solitary but often numerous axillary on the ends of the 

 branches, one inch across. Peduncles thick decurved red, 

 hairy. Bracts rounded, red, velvety, much larger than in 

 R. Teysmanni. Petals narrow linear spathulate round at tip, 

 .5 in. long, .1 in. wide, shorter than the stamens. Filaments 

 .75 in. long, anthers oblong. Capsule .5 in. long, densely 

 red-hairy. 



Pahang. Gunong Tahan (Robinson, Ridley). 



This is the third described species of the genus. One 

 species Rhodoleia Championi of Hongkong, a shrub, has flowers 

 as large as this, but the petals are much broader, and the 

 plant is much more glabrous. R. Teysmanni of Sumatra and of 

 the mountains of the Malay Peninsula is a tree. It is
