 cissime pubescentibus vix paleaceis, pedunculis lateralibus gla- 

 bris, ebracteatis. 



An erect shrub 1 m high or more, the ultimate branches 

 glabrous, pale, at least 1 cm in diameter. Leaves palmately 

 7-lobed, up to 27 cm in length, chartaceous, glabrous, subor- 

 bicular in outline, the lobes oblong-obovate, coarsely lyrately 

 lobed, distantly and sharply toothed, extending to within 3 to 7 

 cm of the base, the sinuses rounded, the lobules of the central 

 lobes two or three, of the lower ones one or two, oblong-ovate 

 to triangular, acute or shortly and sharply acuminate; petioles 

 up to 22 cm in length, the basal part with three or four, spirally 

 arranged, coriaceous, narrow, toothed crests. Inflorescence ter- 

 minal, 8 to 10 cm long and wide, the peduncle stout, about 2 cm 

 long, obscurely paleaceous, the bracts subtending the primary 

 branches lanceolate, up to 2 cm in length; primary branches 

 about fifteen, 2 to 2.5 cm long, slightly pubescent, not paleaceous, 

 each bearing a central, short-peduncled head, and two long- 

 peduncled lateral heads. Sterile flowers of the central head 

 pedicelled, the pedicels about 5 mm long, glabrous or obscurely 

 pubescent, the head subtended by numerous linear to lanceolate 

 bracts and bracteoles, 8 to 13 mm in length, about 10 flowers in 

 each head, the fruits globose, glabrous, 4 to 5 mm in diameter. 

 Peduncles of the lateral heads glabrous, about 2.5 cm long, 

 ebracteate, the heads globose, about 1 cm in diameter, dense, 

 obscurely pubescent, the flowers 25 to 30 in each head, sessile 

 or very shortly pedicelled, about 2 mm long, intermixed with 

 few small scales.
