Hab. Rio Negro, North Patagonia; in sandy soil. 



Root annual or biennial. Stem erect, 2 or 3 feet high, much 

 branched from the base, 'paniculate, glabrous, as is the whole plant 

 except the lower leaves. Cauline leaves trisected, and commonly with 

 lateral segments two-parted, or the larger bitemately divided; the lobes 

 laciniate, three-cleft, or entire, and as well as the segments narrowly 

 linear, sparsely beset, -as is the petiole, with small and spreading 

 hispid-stellsLte hairs. The leaves of the branches and branchlets are 

 for the most part glabrous, simply three-divided, and the filiform-linear 

 segments entire; the uppermost reduced to simple filiform or subulate 

 bracts, subtending the loosely racemose-paniculate pedicels. The 

 latter are an inch or less in length, and obscurely articulated near the 

 apex, one-flowered. Flowers small, 2 or 3 lines long. Calyx naked, 

 glabrous, deeply five-cleft ; the lobes ovate and obtuse. Corolla twice 

 the length of the calyx, apparently pale purple. Stamens, style, &c,
