Prats 122A. Goniothalamus tenuifolius, King. 1, Flowering branch; 2, ripe 
carpels ; 3, inner petals—of natural size; 4, andro-gyneecium; 5, anthers; 6,  pistil— 
enlarged. 
5. GonrorHatamus Prarnianus, King in Journ. As. Soc. Bengal 61, pt. 2, 72. A tree 
50 to 70 feet high; young branches rather slender, pale; all parts, except the imflores- 
cence, glabrous. Leaves membranous, oblong-oblanceolate to elliptic-oblong, abruptly 
shortly and bluntly acuminate, the base slightly cuneate; main nerves 14 to 18 pairs, 
oblique, eee within the margin, prominent beneath; length 7 to 11 in., breadth 
2°25 to 2°8 in.; petiole °85 in. Flowers 1:25 to 1:5 in. in diam., on long pedicels from 
large woody faborulous tubercles at the base of the stem; pediceis 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, triangular 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 smaller, clawed. Stamens numerous; the connective 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 1:25 in. long; stalks -25 im. long. Seed solitary, smooth.

Var. angustipetala, King. Petals oblong-ovate, sub-acute. 
Perak,—King’s Collector. Curtis, No. 2898. 
A species collected by Forbes in Eastern Sumatra (Herb. Forbes No. 3i7 2) 
resembles this closely. The specimens are in fruit only, and the individual carpels 
being a little smaller and less obovoid, it probably belongs to a distinct species. 
Forbes’ specimens: have no flowers. 
PLate 123. Goniothalamus Prainianus, var. angustipetala, King. 1, Leafy twig; 2, 
cluster of flowers from the stem; 3, young fruit; 4, ripe fruit; 5, flower of the typical 
form dissected; 6, inner petals—of natural size; 7 & 8, anthers; 9 & 10, pistils— 
enlarged. 
3 6. Gonioratamus Kunstier1, King in Journ. As. Soe. Bengal 61, pt. 2, 73. A 
shrub 4 to 10 feet high; young branches minutely rufous-tomentose ; the older pale, 
glabrous and much striate. eaves thinly membranous, oblanceolate to elliptic-oblanceo- 
late, abruptly and bluntly acuminate, the base cuneate; both surfaces pale-brown when 
dry, minutely pellucid-punctate, glabrous; the midrib alone puberulous on the upper; 
main nerves 11 to 13 pairs, spreading, curved and inter-arching boldly a little within 
the margin, slightly prominent on the under-surface; length 6 to 9 in., breadth 2 to 
3°25 in.; petiole -85 in., puberulous. Flowers solitary, slightly supra-axillary ; pedicels °15 
in. long. Sepals green, thinly membranous, puberulous, nerved and reticulate, broadly 
ovate, acute, spreading, very slightly cuneate at the base, ‘3 to ‘4 in. long. Petals sub- 
coriaceous, yellow or orange-coloured; the outer lanceolate, acuminate, slightly narrowed 
at the base, puberulous outside, -8 to 1:25 in. long; inner petals about one-third as
