 Stipules minute, setaceous, deciduous. Petiole -J in. long-. Leaves 

 1J-2 in. long", with 3-6 pairs of leaflets, which are oval-oblong", or 

 slightly obovate, apex rounded and mucronate, the lateral ones on short

 hairs. Flowers in dense oblong-conical terminal heads 1 in. or more 

 long. Bracts linear, ciliated, \ in. long. Calyx silvery, 2 lines deep, 

 cut down nearly to the base, the teeth unequal, lanceolate or lanceo-

 linear-oblong, 1-1J in. long, \ in. broad, the lower half narrowed 

 gradually to a very short petiole, firm, both sides finely punctate, the 

 under one grey-green and minutely downy with the midrib raised. 

 Flowers in a long very compound terminal panicle sometimes a foot 

 long, with copious rigid erecto-patent branches, the bracts at the base 

 of the lowest branches like leaves, and higher up growing smaller 

 gradually. Flowers laxly racemose on the branchlets, the lower pedicel? 

 a line long. Calyx campanulate slightly silky, \ line deep, the teeth 

 linear- setaceous, reaching down nearly to the base, the two lowest
