glabrous above, puberulous or glabrate beneath ; margins slightly 

 recurved ; 6 to 9 in. long, 1-5 to 2-5 in. broad ; midrib stout and broad, 

 pubescent on both sides ; main nerves many, more than 12, but difficult 

 to enumerate, nearly horizontal, at first straight, then branching and 

 anastomosing ; petiole -25 to '5 in. long, stout, pubescent. Umbels 

 many-flowered (about 10), on short, often strongly tubercular and 

 cushioned; rachises at the ends of stout pubescent axillary peduncles 

 3 to 10 in. long ; pedicels stout, pubescent, 2 to 3 in. long ; buds large, 

 rounded above, produced below in 5 short recurved angles ; flowers with 

 corolla dark purplish-brown above, cinnamomeous beneath, the corona 

 white or pale yellow. Calyx membranous, puberulous without, scurfy 

 within ; lobes ovate-ciliate, '2 in. long ; scales minute, triangular. 

 Corolla leathery, 2 to 3 in. in diam. ; the puberulous tube a little 

 shorter than the ovate-triangular acute lobes, which are at first much 

 incurved, afterwards spreading. Coro7ia of 5 laterally compressed pro- 

 cesses; the lower lobes erect, obtuse, deeply 2 -cleft and pubescent in the 

 clefts ; the upper lobes also erect-subulate-acuminate. Staminal-column 

 short, broad ; anther-cells broad ; appendages membranous, broadly 

 winged, acuminate ; pollen-masses flattened, oblong, truncate at both 

 ends, '075 in. long, attached by short slender caudicles to the thick, 

 trigonous, horny, brown pollen-carriers. Style-apex pentagonal, the 

 angles rounded below, ridged above, the ridges joining in an acuminate 

 cone. Follicle 1, lanceolate-acuminate, 8 to 9 in. long, 1 in. broad ; 

 pericarp leathery, opening flat, at first puberulous, afterwards glabrous, 

 striate when dry. Seeds obovate, flask-shaped, "2 in. long, trigonous 

 above, truncate at tip and bearing a silky white coma 2 in. long ; testa 

 corky, pale brown ; albumen copious ; cotyledons thick, ovate, cordate 

 at base, -1 in. long ; radicle -075 in. long, thick. Hook. Bot. Mag.

 apex and base ; glabrous on both surfaces and pale, especially beneath ; 

 margin hardened, nerve-like, slightly recurved ; 1-5 to 2-5 in. long, 1 to 

 1-5 in. broad; nerves prominent when dry; midrib slender; main nerves
