tube, narrow; corolla-lobes whiter than the tube. Capsules very numerous, 31 in., 
fusiform, beaked, shorter than the slender pedicels, nearly glabrous.—One sheet of 
Wallich’s 6107 is U. Gambier, Roxb., another is U. ovata, 
17. U. lanosa, Wail. in Roxb. Fl. Ind., ed. Carey & Wall. ii. 181; Cat. 
6110; branches subterete hairy, leaves very short-petioled ovate-lanceolate 
finely acuminate slightly hairy above softly so beneath, de zeg 2-partite, 
peduncles all axillary short bracteate in the middle, calyx-lobes long linear, 
capsules long-pedicelled glabrous. Nauclea lanosa, Poir. Dict. Suppl. iv. 64.

Prxaxa, Wallich, Phillips.—DrsrRis. Sumatra, Malay Islands. 
Slender. Leaves 3-4 by 13-2 in., membranous, yellow-brown, opaque above when 
dry with scattered hairs or glabrate, paler beneath with soft appressed hairs, base 
acute or rounded; nerves 6 pair, very distinct, obliquely arching, transverse nerves 
very slender; petiole 4 in.; stipular segments ovate-oblong, recurved, quite glabrous. 
Peduncles 1-2 in., narrowed from the base; bracts 4, slender, recurved. Heads 2 in. 
diam., in fruit 2 in.; receptacle very small and pedicels slightly hairy; calyx-lobes 
longer than the tube. Capsules fusiform, 4 in., glabrous, on filiform pedicels twice 
their length, acute, hardly beaked.—I have seen no corollas, Wallich describes the 
tube as capillary, smooth, and the lobes as a little hairy, 
18. U. Lobbii, Hook. f.; branches subterete glabrous, leaves short- 
petioled elliptic-ovate abruptly obtusely acuminate glabrous membranous, 
nerves 7 pair, stipules 2-fid, peduncles all axillary bracteate above the middle, 
ealyx villous, lobes linear longer than the tube, corolla-tube glabrous, lobes 
pubescent. 
SINGAPORE, Lobb (n. 332). 
Slender, very glabrous. Leaves 3-34 by 13-12 in., green when dry, shining above, 
almost so beneath; nerves slender, arching upwards, with minute axillary tufts and a 
few scattered hairs; petiole slender, 4 in.; stipules membranous, reflexed. Pedwneles 
narrowed from the base, shining; bracts 6, large, ovate, acuminate, membranous, 
reflexed. Heads 1 in.; flowers sessile. 
19. U. ferrea, DC. Prodr. iv. 348; branches subterete, peduncles and 
petioles and leaves beneath densely tomentose or villous, leaves short-petioled 
ovate or elliptic-ovate obtusely acuminate with scattered hairs and tomentose 
on the 8-9 pair of nerves above, stipules 2-fid and large bracts tomentose, 
peduficles all axillary bracteate above the middle, calyx hirsute, lobes very 
long filiform, corolla glabrous, capsules slender long-pedicelled. Nauclea ferrea,

Rather robust and very hairy. Leaves 3-44 by 2-21 in., rather coriaceous, rusty- 
brown above when dry, paler beneath, base rounded, nerves strong spreading, trans- 
verse ones distinct; petiole 3 in.; stipules broad, recurved.  Peduncles 1-1} in., 
vs upwards; bracts 4-6, nearly 9 in., ovate, acuminate. Heads 2 in. diam., 
Proffe" uot much larger; flowers subsessile; calyx-tube much shorter than the lobes, 
Capsules A in., fusiform, shorter than the pedicels, acuminate, hairy.— U. Horsfieldiana, 
Miq., is a variety with leaves less hairy beneath. Cuming’s 1128, from the Philip- 
pines, is a closely allied species with much smaller bracts and stipules,
