A. platypll^lla. Winter annual, wholly glabrous, somewhat glaucous : leaves all or 

 chiefly in a rosulate radical tuft, broadly cuneate or obovate, mostly rounded at summit, ses- 

 sile, spiuulose-denticulate, somewhat veiny (inch or two long) ; those of stem reduced to 

 very small scattered bracts : stem slender, a foot or two high, at summit deliquescent iuto a 

 diffuse cymose panicle of few or numerous slender-pedunculate heads : involucre quarter- 

 inch high, about half the length of the corollas (these white or with purple base) : akenes 

 2 lines long, at maturity nearly equalling the narrow and open bracts of the involucre, white, 

 sometimes with 4 or 5 very thick corky ribs and much smaller alternate ones, sometimes 

 more terete and obscurely costate, the truncate summit wholly destitute of the border of 

 Malacothrix, its areola small: receptacle rather fleshy, scrobiculate. Malacothrix? pluty-

210. APC)GrON, Ell. ('ATroryon', beardless, i. e. no pappus.) Low annuals
