Pflanzenreich, iv. 32. 
Shrub 5 or 6 ft. tall; twigs red-tomentose as are the young leaves. 
Leaves sub-coriaceous thin, elliptic-lanceolate or oblanceolate, 
long-acuminate, base narrowed acute, above glabrous, beneath 
thinly cinnamon-red-pubescent; nerves 6 pairs, thin moderately 
prominent beneath; 3*5 to 5 in. long, 1-5 in. wide; petioles densely 
red-tomentose beneath, sometimes glabrescent, *08 in. long. 
Flower clusters axillary sub-globose. Flowers few. Bracts 
minute, ovate red-tomentose. Male flowers sessile. Sepals lan¬ 
ceolate. Petals obcuneate, cream-colour. Disc lining calyx cup. 
Pistillode columnar lobed. Female flowers unknown. Capsule 
3-lobed, black glabrous, -25 in. long. Hab. Woods, Singapore, 
Garden Jungle (Ridley). Muar (Curtis). Perak (Scortechini). 
Penang, Waterfall (Curtis). 
I have seen no type of C. vestitus (true), a Bornean species, but it is 
described as having a round-based ovate leaf, and is certainly different from 
Jablonsky’s variety perakensis.

Bridelia rufa Hook. fil. F.B.I. v. 273. 
Shrub 8 to 12 ft. tall, bark rough; branchlets densely red- 
tomentose. Leaves thinly coriaceous, glabrous above except red- 
tomentose nerves; in young leaves, red-hairy beneath on nerves, 
elliptic-lanceolate cuspidate, base rounded; nerves 8 pairs elevate 
beneath; 5 to 6 in. long, 2 to 3 in. wide; petioles 'i in. long, red 
tomentose. Flowers sessile in small heads *1 in. across. Bracts 
red-tomentose ovate. Male flowers. Sepals lanceolate glabrous 
except the red-tomentose tips. Petals small round. Pistillode in 
male hairy. Female flowers, sepals as in male. Petals oblong- 
spathulate, sub-crenulate. Disc toothed. Ovary ovoid hairy. 
Hab . Penang at 100 to 400 ft. altitude (Kunstler). 
I am by no means sure that this is not a state of C. perakensis, but it 
is much more tomentose, the leaves thicker and rounded at the base. 
5 . ACTEPHILA, Bl. 
Shrubs or small trees. Leaves simple alternate. Flowers 
axillary in imbricating bracteolate heads or racemes. Calyx 5-fid 
nearly to base. Petals 5 much smaller attached outside the disc. 
Stamens 5 surrounding a trifid pistillode, filaments free or united 
only at base. Disc cup-shaped or annular, edge crenulate. Ovary 
sessile sub-globose trilocular, locules 2-ovuled. Styles 3, minute. 
Capsule dry, loculicidal or cocci breaking into 2 valves, bearing 
a central columella, 1- or 2-seeded. Seeds triquetrous, back convex 
with 2 plane lateral surfaces meeting at an acute angle; albumen 
scanty or 0, cotyledons contort, fleshy. Species about 10, East
