1. CLEISTANTHUS BRACTEOSDUS, Jabl. in Pflanzenreich IV. 147; 
Vill, 41; (1915). A small tree. Branchlets, stramineous-brown, 
glabrous, 4—8 mm. thick ; flowering twigs lateral from the branch- 
lets, 5—15 cm. long, 1—2 mm. thick, rusty scurfily-pubescent or 
glabrescent; internodes -5—1'5 cm. long. Lamine coriaceous, ob- 
long, oblanceolate or oblong-ovate, 16—40 cm. long, 6—13 cm. 
broad, with caudately acuminate apex and narrowly to broadly 
cuneate or round base; upper surfaced olivaceous, subnitid, gla- 
brous, obscurely reticulate, with slender indented midrib and nerves ; 
lower surface dull, pale cinnamon to almost silvery, very finely 
closely adpressedly pubescent, except on midrib and nerves, with 
minute rusty hair-like scales sparsely interspersed, the prominent 
midrib and nerves glabrous or sparsely minutely ramentaceous ; 
nerves 14—20, distinct to the margin; cross nervules numerous, 
close, subparallel, connected irregularly to form a rather open and 
transversely elongate irregularly polygonal reticulation, petiole 
very stout, subterete, glabrous, closely wrinkled, 1-5—2 cm. long; 
stipules not seen. Flower-clusters strung along the flowering twigs 
at short intervals. each in the axil of a stipuliform bract, of rather 
few flowers and one sex predominating in a cluster; bracts broadly 
ovate, acute, 7 mm. long and broad, + —rufous-pubescent and 
often mesially narrowly bialate on the outer surface, glabrous 
and smooth on the inner; the mesial dorsal alee sometimes united 
by their inner margin and prolonged into an abrupt caudiform 
apex; bracteoles broadly ovate, thinly membranous or almost 
hyaline, glabrous except for a few minute adpressed rufous hairs 
on the subcarinate outer surface. < flowers seen only in young 
bud; entirely glabrous sepals lanceolate; petals ovate. 9? perianth 
seen only in fruiting stage, sessile, ovoid, 4—5 mm. long, entirely 
glabrous; sepals deltoid; petals obovate-spathulate, 1 mm. long; 
annulus of the disk irregularly dentate ; ovary not seen. Capsule 
on a stout, terete, glabrous, 8 mm. long pedicel, the base of which 
is surrounded by the remains of the perianth, glabrous, crimson 
turning black, obscurely reticulate, 9 mm. long, 1°3 cm. broad. 
Seeds cordate-ovate, 7 mm. long, 6 mm. broad, 4—5 mm. thick, 
slightly compressed antero-posteriorly, with convex ecarinate dorsal, 
and 2 subconvex ventro-lateral surfaces separated by a rounded 
ridge which has a small irregular hilar depression at its lower end ; 
surface of seed, brownish-black, glabrous, not quite smooth; apex 
rounded ; base cordately retuse.
