6. Cleistanthus venosus sp. nov. 
Arbuscula monoica; floribus in capitulis paucifloris spicatis vel sub- 
spicatis foliose bracteatis dispositis, pentameris, calycis lobis lanceolatis 
acuminatis extus villosis ; petalis ovatis, pedicellatis, sublobatis ; fructibus 
3-lobatis, 3-locularibus, ovulis 2; foliis anguste ellipticis vel oblongis, 
acuminatis, venis conspicuis. 
Flowers borne in spicate clusters usually in threes except at the apices 
of the branches, each cluster subtended by a foliose bract 9-14 mm long 
and 3-3.5 mm wide, lanceolate or oblanceolate, acuminate, having a 
stipule 2.5 mm long on each side of its base; flowers of both sexes in 
same cluster, sessile or subsessile: male flowers with the calyx 4.5-5 mm 
long, divided for about three-fourths of its length into 5 valvate lanceolate 
acuminate lobes, rounded or refuse at the apex, appressed-villose on the 
outer side; petals 5, ovate, 3.5 mm long, 3.5 mm wide, at the base 
truncate and sharply contracted into a slender claw about 0.3 mm long, 
villose on the outer surface, towards the apex somewhat 3- or 4-lobed; 
disk cupular, 0.8 mm long, 5-angled, extra-stamineal, conspicuous; andro- 
gynophore 1-1.5 mm long, filaments 5, 0.8 mm long, anthers dorsifixed, 
introrse, oblong-lanceolate, cordate at the base, 0.7 mm long; rudimentary 
ovary borne at the summit of the androgynophore and surrounded by 
the anthers, ellipsoid, 1.3 mm long, including a stipe 0.2 m m long, 
contracted at the apex into a blunt beak: female flowers with bracts 
sepals and petals as in the male flowers and persistent in fruit, the disk 
conspicuously double, both wide, cupular or lobed; ovary subglobose, 
appearing to be about 2 mm in diameter, but really considerably less' 
owing to the dense villose pubescence which covers it, 3-celled, each cell 
with 2 ovules 0.5 mm long; styles 3, united with one another at the base, 
each about 2 mm long, bifid at the apex : capsules strongly 3-lobed, 
3-celled, 1-1.2 cm long, and of similar diameter, their surface covered 
with small vermicular lines eycept at the contracted base, more or less 
villose especially near the base and in the sinuses of the lobes; seeds 2, 
collateral, hardly developed beyond those in the ovary, ellipsoid, the 
embryo nearly the length of the seed, its cotyledons straight. 
A small tree attaining 7.5 m in height, with a trunk 10 cm in diameter, 
the young bark grayish to brownish, slightly striate and lenticellate, 
glabrous except the parts of the inflorescence already noted and the 
villose youngest shoots; leaves alternate, borne on petioles 4. 5-6. 5 mm 
long, the lamina entire, subcoriaceous, narrowly elliptical or oblong, 10-18
