 involucre 4 or 5 lines high, of oblong-lanceolate acute bracts : rays broadly oblong : bracts 

 of the receptacle nearly entire and glabrous : akenes linear-oblong, thickish, silky-hairy at 

 least above : papj)us of two oblong or linear caducous small and tliin paleoe, which some- 

 times do not surpass the hairs of the akene. — Bot. Mex. Bound. 90, & Proc. Am. Acad. xx.

 H. dealbAtus, Gray, p. 280. Collected in excellent specimens by E. L. Greene, 1885, on 

 Cape San Queutin, Lower California; tlie foliage very silvery and soft with the dense pannose 

 tomentnm. From the habitat, the Eiicelia-Y\kG aspect, and the whole description, this is evi- 

 dently Encelia niceu, Benth. Bot. Suljjh. 27, the new specimens with peduncles even longer than 

 described, and the bracts of the involucre come near to ovate-lanceolate. The small and narrow 

 palese of the pappus are so very caducous from the ovary tliat Bentham overlooked them.
