cribcd here, that I refer it without any hesitation to this genus. 
Mi Curtis* leaf specimens of this have, I understand, received from 
M. Heim the MSS. name, Pierrea penangiana. The genus Pierrea 
has been founded by M. Heim (Bull. Soc. Linn. Paris, 1891, p. 958, 
and u Recherches sur les Dipterocarpac&es p. 78) on specimens of 
which the author has not (as he admits) bad the advantage of seeing 
the flowers. The vernacular name of this tree in Penan g is Chengah, 
and its timber is, according to Mr. Curtis, very valuable. In the 
Stato of Perak, on the mainland almost opposite Penang, another species 
(B, Wrayi) receives a similar vernacular name. 
6. Balanocarpus Wrayi, King n. sp. A tree: young branches 
slender, dark- col ourcd, glabrous. Leaves coriaceous, narrowly oblong, 
gradually tapering from the middle to the acute apex ; the base sub- 
cuneate or rounded, slightly unequal -sided : both surfaces glabrous ; 
main nerves 7 or 8 pairs, curved, oblique, slightly prominent beneath s 
length 2*25 to 2*75 in., breadth -75 in. ; petiole "25 in., transversely 
wrinkled. Panicles axillary and terminal, nearly as long as the leaves. 
Flowers unknown. Fruit ovoid, much apiculate, glabrous, '6 in. long, 
covered in its lower two-thirds by the persistent sub-accrescent glabrous 
calyx ; outer two sepals smaller than the others, elliptic, obtuse, the 
inner three rotund, all thickened and concave. 
Perak : Wray, No. 813. 
Collected only once and without flowers. According to Mr. Wray 
the timber of this tree is valuable, and its vernacular name is Chingi, or 
Chingal. I refer this {in spite of the absence of flowers) to Balanocar- 
pits, the other species of which it so closely resembles. 
7. Balanocarpus Hemsleyanus, King, n. sp. A tree 50 to 100 feet 
high : young branches rather stout, rough, minutely lenticellate, pube- 
rulous. Leaves coriaceous, elliptic-oblong, sometimes slightly obovate, 
shortly and abruptly acuminate, slightly narrowed to the rounded or 
sub-emarginate base : upper surface glabrous except the minutely 
tomentose midrib ; the lower soabrid from minute rigid stellately hairy 
tubercles which are most abundant on the stout midrib and nerves: 
main nerves 18 to 20 pairs, oblique, parallel, very prominent on the 
lower, obsolete on the upper, surface ; length 7 to 12 in., breadth 325 
to 5 in. ; petiole "6 to *9 in. scabrid, pubescent. Panicles axillary or 
terminal, 3 to 7 in. long, scurfy stellate-pubescent ; flowers rather 
crowded on the lateral branchlets, '5 in. long, Sepals sub-equal, 
broadly ovate, acute, yellowish-tomentose externally, glabrous internally. 
Petals twice as long as the sepals, or longer, elliptic, oblique, obtuse, 
glabrous except a broad adpressed-s eric eons band externally. 
Stamen* 15, in three rows: the filaments dilated, unequal, longer than 
426
