persistent, large. Flowers sessile, in solitary or ternate, pedunculate 

 heads ; the peduncles often thickened near the apex and bearing caduc- 

 ous bracts, often of large size, mostly caducous ; the flowers mixed with 

 bracteoles consisting of long thin stalks and conical hairy heads, or 

 ebracteolate. Calyx-tuhea closely adpressed ; but not united with each 

 other ; the lobes 5, deciduous, filiform or spathulate, often thickened at 

 the apex and hairy, valvate in aestivation. Corolla infundibuliform ; 

 the lobes 5, short, imbricate, the throat glabrous. Stamens 5 ; the 

 anthers oblong or linear, included in the tube of the corolla ; filaments 

 very short. Style elongate, rather stout : stigma sub-globose or globose- 

 ovoid. Ovary 2-celled, the placentas pendulous ; ovules imbricate. 

 Fruit of 2 cocci, often separating from the persistent axis, dehiscent. 

 Seeds flattened ; the testa with a wing, bifid at one end, acute at 

 the other. — Distrib. About 30 species mostly tropical and Indo- 

 Malayan.

1. Nauclea Gageana King. n. sp. A tree ; young branches rather 

 stout, slightly compi^essed, when dry pale-brown. Leaves coriaceous, 

 broadly ovate-eliiptic (sub-rhomboidal) gradually narrowed to the 

 obtuse apex, the base cuneate ; both surfaces quite glabrous, the upper 

 shining (when dry); the lower dull, reticulate; main-nerves 8 to 10 

 pairs, spreading, prominent on the lower surface : the midi'ib very bold ; 

 length 6 to 8 in. ; breadth 3"5 to 4"5 in. ; petiole '6 to "8 in., flattened, 

 winged in its upper part. Gapitules about 1"5 in. in diam., solitary or in 

 pairs. Peduncles 1 in. long, with a pair of large (125 in. long) sub- 

 persistent bracts above the middle. Calyx short, cylindric, densely 

 sericeous ; the mouth very short, with 5 broad truncate lobes. Corolla 

 infundibuliform, '4 to "5 in. long, outside glabrous in its lower, sericeous- 

 strigose in its upper part; inside glabrous; lobes of the mouth 5, ovate. 

 Style exserted, glabrous ; stigma ovoid. Fruit villous. Bracteoles of the
