49 S. ? INCONSPI'CDA (Bartl. in herb. Haenke, ex D. C. prod. 

 4. p. 557.) plant suffrutescent ; branches ascending, somewhat 

 hexagonal, glabrous at bottom, but clothed with powdery down 

 at top ; leaves linear-oblong, acuminated at both ends, glabrous, 

 with scabrous edges ; bristles of stipulas longer than the sheath ; 

 heads of flowers terminal, girded by 4-leaved involucra ; teeth 

 of calyx 4, nearly equal, acuminated. Ij . S. Native of Peru, 

 on the mountains. Branches truly tetragonal, but 2 of the sides 

 are very narrow, and the other 2 are broader, convex, and 

 almost keeled in the centre of the convex part ; therefore they 

 are said to be somewhat hexagonal. The habit is that of Bor-

 stipulas sheathing, ciliated by bristles ; whorles of flowers axil- 

 lary and terminal, small, sessile ; fruit hispid. 0. H. Native 

 of Peru, on the mountains. Flowers white. It is probably a 

 species of Borreria from the fruit being crowned by the 4 teeth 

 of the calyx ; but the habit is almost that of S. tenuior.
