C. laevis was founded on a solitary and poor specimen, which I am unable 
to distinguish from C. heterophyllus, also founded on a solitary and poor speci- 
men. The presence or absence of the small leaves is no criterion of specific 
difference as they are caducous. The appearance of the reticulation on the 
lower surface varies with the age of the leaf. In young leaves the nerves and 
nervules appear as yellowish and ‘‘ unfinished’”’ on a light chocolate back- 
ground; in older leaves the reticulation is distinct and similar in all the speci- 
mens to that of the type of C. heterophyllus. 
12. CLEISTANTHUS GRACILIS, Hook. f. 277. Asmall bushy tree 
5—8 m. high ; twigs divaricate, glabrous, 1—2 mm. thick. Lamine 
subcoriaceous, lanceolate, 2°5—6°5 cm, long, 1—3 cm. broad, with 
acuminate or caudate apex and acute base, entirely glabrous ; 
upper surface brown-olivaceous, subnitid, lower yellowish-brown, 
dull ; nerves 5—7, anastomosing near the margin; petiole slender, 
subterete, 3—4 mm. long; stipules not seen. Flower-clusters 2—5 
mm. in diam., of comparatively few flowers, ¢ and 2 mixed, 
bracteoles ovate, hirsute on outer, glabrous on inner surface. ¢ 
flowers sessile, ovoid acute in bud, 2 mm. long, glabrous, sepals 
unequal, 2 short deltoid and 3 longer lanceolate ; petals extremely 
minute, spathulate ; disk circular pulvinate, sublobulate ; pistillode 
columnar, undivided, caducously scurfy-tomentose. 92 flowers ses- 
sile, larger than the ¢ , 2.5—3 mm. long, fusiform in bud, glabrous ; 
sepals subequal, lanceolate ; petals linear-oblong or subspathulate, 
less than ‘5 mm. long; disk lining the obconical calyx cup and ex- 
tended above it as 5 broad subdentate +-— connivent lobes; ovary 
ovoid, densely hirsute ; styles short, united at the base, undivided ; 
stigmas clavellate. Capsule sessile, 8 mm. in diam., sparsely hairy 
at the base. Seeds ovoid-oblong, 5 mm. long, 4 mm. broad, 3°5 
mm. thick, with convex carinate dorsal and 2 ventro-lateral irre- 
gular sub-convex surfaces. Jabl. in Pflanzenreich, |.c. 15, C. dasy-

The type sheet is K.C. 1709 in Kew Herbarium. Curtis No. 2810, on which 
Williams founded C. dasyphyllus seems to me merely a specimen of C. gracilis, 
with a predominance of male flowers. The adult leaves are broader in propor- 
tion to their length in Curtis’ specimens than in the type of C. gracilis, but the 
younger leaves are alike in both.
