Cleistanthus.] CXXXV. EUPHORBIACER. (J. D. Hooker.) 277 
8. C. levis, Hook. f.; quite glabrous, leaves 3-5 in. coriaceous ovate 
or ovate- or elliptic-lanceolate base acute or rounded faintly reticulate 
beneath, nerves 6-10 pair very slender, flowers solitary or few together 
axillary or in slender axillary spikes quite glabrous, calyx-lobes ovate-lan- 
ceolate, petals obovate truncately retuse, disk of male cupular lining the 
calyx-tube, fruit (young) sessile hairy. 
SINGAPORE; jungle behind the Botanical Gardens, Murton. 
A small tree, 15-20 ft. ; branches smooth, woody, but slender, terete. Leaves 
1i-23 in. diam., pale grey above when dry, pale brown beneath, quite smooth ; 
petio.e $-1 in. Flowers very few seen ; bracts very small, ovate or rounded, slightly 
ciliate.  Ca/yz of male iin. diam. Disk with a raised obscurely crenate border. 
Slaminal column slender; pistillode short, stout, cylindric, truncate. Young fruit 
deeply 3-lobed at the top, sparsely hairy.— Better specimens of this very distinct 
Species are much wanted. 
9. C. malaccensis, Hook. f; quite glabrous except the flowering 
shoots, leaves 3-6 in. coriaceous elliptic-oblong or lanceolate obtusely sub- 
caudate acuminate, base acute, nerves 4-6 pair slender, flowers minute in small 
villous axillary and paniculately spiked clusters glabrous, calyx-lobes of 
male ovate of fem. lanceolate, petals of male spathulate of fem. rounded, 
Ovary with a few long erect caducous hairs, styles simple. 
Maracoa, Maingay (Kew Distrib. 1373). 
Habit of C. chartaceus; branches stout; bark pale. Leaves dark brown when 
dry, paler beneath, very smooth on both surfaces, cross-nervules very faint, base 
suddenly narrowed and shortly produced on the very short petiole, Clusters 1-3 in. 
diam. ; spikes stout, often recurved, forming terminal panicles a foot long and less with 
2 leaf here and there; bracts rusty-villous. Calyx 4*5 in. diam., fem, rather the largest, 
with much narrower apparently deciduous lobes (they easily break away from the 
flowers), Disk of male pulvinate, of fem. tubular. Filaments very short. — Pistillode 
conical. Ovary elongate ovoid; styles apparently not 2-fid. 
10. C. lancifolius, Hook. f.; branches and leaves glabrous, leaves 
4-5 in. elliptic-lanceolate very finely acuminate base acute, nerves 12-15 
Pair very slender, fem. fl. solitary or few together axillary clothed at the 
ase with pubescent bracts, calyx glabrous lobes lanceolate acuminate, 
petals spathulate entire claw rather long, ovary hirsute. 
TENASSERJM, Helfer (Kew Distrib. A875). 
, Branches slender, terete; tips pubescent. ^ i an 
thinly corinceons, nerves slender, tapering point nearly lin. long; petiole j in. 
Flowers (unexpanded) 2 in. long. Petals nearly half as long as the calyx. Ovary 
subglobose, enclosed in the disk; styles 2-lobed at the tip.— Can this be Kurz's C. 
slenophyilus? if so, the ovary of that plant is erroneously described as glabrous. 
ll. C. gracilis, Hook. f; quite glabrous, branches very slender, 
leaves 13-2 in. elliptic-ovate obtusely caudate base acute, nerves o-/ pair 
very faint, flowers few in axillary clusters and spikes glabrous, calyx-lobes 
anceolate, petals of male very minute linear of fem. elliptic, ovary hirsute 
enclosed in the membranous elongate 5-partite disk, capsule sessile quite 
glabrous, 
PERAK, Scortechi i. > King’s Collector. . . 
A much-branched tree 8 25 fi ; branchlets divaricate, ultimate almost filiform. 
€aves rather coriaceous, pale when dry, sometimes a little glaucous beneath, nerves 
very obscure ; petiole 2 in., very slender; stipules short ovate. Flowers +5 in. diam., 
male and fem. together ; bracts minute, ciliate. Pistiliode tomentose. Disk-lobes 
of fem, with trancate tips, together forming a membranous cone. Capsule about 
in. long.—A very distinct species, allied to C. heterophyllus and patulus. 
Leaves spreading, 2-1] in. diam.,
