of 5 or 6 ft., with rigid divaricate branches, lioury or rusty with a close to- 

 mentnm. Leaves ovate or broadly oblong, veiy obtuse, 1 to 3 iu. long, lioary 

 on both sides and especially underneath with a close tomentum. Flower- 

 heads very shortly peduncalatCj attaining sometimes 1\ in. diameter. Outer 

 lu'acts 5, broadly ovate, herbaceous, tomentose, 4 or 5 lines long, united at 

 the base. Inner oues about 10, longer, narrower, and more petal-like, those 

 of the first 1 or 2 series broadly elliptical, obtuse, pubescent, passing into a 

 few (iimermost) much narrow^er ones, sometimes linear and acute. Petals linear, 

 ciliate, quite concealed within the head. Stamens much longer than the 

 bracts. Cocci 3 or 4 lines long, coriaceous, glabrous, smooth or transversely 

 wrinkled,

ft. Leaves obovate or oblong, very obtuse, sometimes all under -| in., and 

 rarely exceeding 1 in., ratlier tlvick, hoaiy-tomentose above, and densely and 

 softly tomentose underneath. Flower-beads much smaller than in D. grmicli'
