Heads usually many-flowered ; the ray-flowers 5-12, ligulate, pistillate, in 

 a single series ; those of the disk tubular, perfect. Scales of the subglobose 

 involucre in a single series, as many as the rays, carinate-complicate and en- 

 closing their achenia. Receptacle flat, ujiked evrept tl'e n-i-Trgin, which is 

 furnished with 1-2 series of chaffy scales, usually more or less united. Co- 

 rolla with a pubescent tube ; the rays slightly exserted. Branches of the 

 style in the disk-flowers lanceolate, acute or acuminate, the margins minutely 

 hispid. Achenia of the ray and disk similar, compressed, neariy straight, 

 oblong-obovate, glabrous (minutely and closely striate), destitute of pappus, 

 usually more or less one-nerved or angled on each side.— Annual or biennial 

 hairy and glandular herbs (natives of Chili, California, & Oregon) ; with ob- 



est often opposite, the others alternate.'' Heads bracteate, sessile, or on short 

 peduncles, somewhat racemose. Flowers pale yellow : anthers brown.
