72 G. King — Materials for a Flora of the Malay Peninsula. [No. 1, 



"35 to '45 in. long. Sepals free, large, membranous, green, many-nerved 

 and reticnlate, broadly ovate, acnte or acuminate, glabrous, '75 to l'l in. 

 long. Petals whitish, thinly coriaceous, faintly nerved, broadly lanceo- 

 late, acuminate, much contracted at the base, pubescent, 1 to 1*2 in. 

 long, (smaller in var. aborescens) ; inner petals less than half as long, 

 ovate, acuminate, the base contracted, pubescent. Anthers numerous, 

 compressed, the apices broad, flat, pubescent. Ovaries few, narrow, short, 

 1 rarely 2-ovuled ; the style long, straight, thickened upwards ; stigma 

 hollowed like a funnel, the edges toothed. Ripe carpels partly enveloped 

 by the persistent calyx, ovoid, very slightly apiculate, puberulous or 

 glabrescent, '4 to '5 in. long ; stalks 2 in long. Seeds usually 1, rarely 2.

Var. aborescens, King ; a small tree 15 to 25 feet high ; leaves 4 to 

 4'5 in. long ; petals coriaceous, adpressed-pubescent, about half as long 

 as in the typical form ; sepals only "3 in. long. 



Perak ; elevations from 2,000 to 3,000 feet, King's Collector. 



This possibly ought to be considered a distinct species ; but as its 

 anthers and ovaries are exactly the same as in the typical shrubby 

 G. tenuifolius, I prefer to consider it a mountain form of that species. 

 Both the typical form and the variety have remarkable stigmas, shaped 

 like funnels and with toothed edges. 



3. GtOniothalamus Prainianus, King, n. sp. A tree 50 to 70 feet 

 high : young branches rather slender, pale ; all parts, except the in- 

 florescence, glabrous. Leaves membranous, oblong-oblanceolate to elliptic- 

 oblong, abruptly shortly and bluntly acuminate, the base slightly 

 cuneate ; main nerves 14 to 18 pairs, oblique, inter-arching within the 

 margin, prominent beneath ; length 7 to 11 in., breadth 2'25 to 2'8 in., 

 petiole '35 in. Flowers 1*25 to 1*5 in. in diam., on long pedicels from 

 large, woody, puberulous tubercles at the base of the stem : pedicels 2 

 to 4 in. long with two minute bracteoles at the base. Sepals coriaceous, 

 united so as to form a spreading cup with three broad sub-acute tri- 

 angular teeth, puberulous outside, glabrous inside. Petals thickly 

 coriaceous, pale yellow ; the outer row large, obovate-rotund, concave, 

 incurved, (ovate-oblong in var.) pubescent on both surfaces, nearly 1 in. 

 long : inner row much smallei', clawed. Stamens numerous, the connec- 

 tive prolonged into a blunt, conical, puberulous, apical process. Ovaries 

 narrowly oblong, glabrous ; style cylindric, not lobed, truncate. Ripe 

 carpels obovoid, slightly apiculate, tapering to the base, glabrous, 1 to 

 125 in. long ; stalks '25 in. long. Seed solitary, smooth.

Var.: angustipetala, King; petals oblong-ovate, sub-acute.
