SYNGENESIA— POLYGAM.-yEQU. Crepis. 373 



ance. Stem from 1 to 2 feet high, erect, round, furrowed, hol- 

 low, letify ; unbranched below ; panicled above. Leaves with 

 sharp, shallow, partly reversed teeth j radical ones obovate, 

 tapering down intoa winged/oo/s^rtZA:; upper onit^ sessile, acute, 

 clasping the stem with their arrow-shaped, or heart-sh:iped, 

 bases. Panicle corymbose, with many long, wide-spreading, 

 striated branches. Bracteas small, acute, solitary at the base of 

 each branch or flower-stalk. FL solitary at the extremities of 

 the branches, erect, small, yellow, closing about noon. Cal. 

 truly that of a Crepis, the scales composing the outer one small, 

 membranous and lax, finally withering, if not deciduous ; those 

 of the inner parallel, linear ; at first smooth, even, and flat, but 

 acquiring, as the seed ripens, a strong, hard, rounded, promincn 

 mid-rib, which last is a peculiar character. Fiords downy ex- 

 ternally. Seed slender, finely striated, beaked. Down rough, 

 sessile on the summit of the beak, and wanting a real stalk ; 

 but it seems to me that, as the stalk varies in length in several 

 species, this part is of less weight in the generic character than 

 the calyx, which is so peculiar. The Jlorets being rather nume- 

 rous, in several rows, agree too ill with the essential and very 

 peculiar character of Prenanihes. The receptacle is small', 

 slightly cellular.
