6. A. 2^l(^ntaginifolia (Hook.! I.e.): sterile stems stoloniferous or fla- 

 gelliform, the flowering simple and scape-like; leaves silky-villous on one or 

 both sides when young, but when old glabrous above and canescent beneath ; 

 the radical petioled, oval or obovate-spatulate (usually large), 3-nerved ; the 

 cauline lanceolate, appressed; heads in a small crowded corymb; scales of 

 the involucre with white (rarely purplish) erose or crenulate tips; those of 

 the sterile plant obtuse, of the fertile narrow and mostly acute ; achenia mi- 

 nutely glandular-papillose. — A. plantaginea, DC. ! I.e. Gnaphalium plan-

 Near Philadelphia, Mr. Lea! &c. April-May: in the Southern Stales, 

 Feb.-March. — Plant 4-10 inches high. Radical leaves often 2-3 inches 

 long, and one or two wide. Pappus of the sterile flowers sparsely barbellate, 

 more or less evidently thickened towards the apex. — Plantain-leaved 

 Cud-weed. 



7. A. racemosa (Hook.! 1. c.) : sterile stems stoloniferous; leaves tomen- 

 tose beneath; the upper surface and the scape-like stem nearly glabrous; the 

 radical oval or obovate-spatulate, petioled, somewhat 3-nerved ; the cauline 

 oblong or lanceolate ; heads loosely racemose-paniculate ; scales of the in- 

 volucre nearly glabrous, greenish; those of the sterile plant obtuse; the inner 

 of the fertile heads narrow and acute; achenia perfectly smooth. 



Alpine woods of the Rocky Mountains (probably about lat. 52°), Drum- 

 mond! — Fertile plant often a foot or more in height ; the heads loosely dis- 

 posed in a long racemose panicle. Pappus in the sterile heads minute- 

 ly scabrous, very obscurely thickened above : the style slightly 2-cleft at 

 the apex. 



8. A. dimorpha: csespitose, depressed, somewhat stoloniferous; leaves 

 crowded on the short branches of the suffruticose caudex, oblong-spatulate or 

 nearly linear, silky-villous ; heads solitary, on short peduncles, scarcely ex- 

 serted beyond the leaves ; scales of the involucre brownish, the exterior 

 woolly ; the inner scarious, lanceolate, acute in the sterile, and acuminate 

 in the fertile heads; pappus of the former capillary, sparsely and minutely 

 barbellate towards the apex. — Gnaphalium (subgen. Omalotheca, § Hetero- 

 phania) dimorphum, Nutt.! in trans. Amer. phil. soc. {n. ser.) 7. p. 405. 



Black Hills of the Platte, Nuttall ! May.— Plant 1-3 inches high. Leaves 

 an inch long; in the fertile plant 2-3 lines, in tlie sterile scarcely a line wide. 

 Heads twice as large as in Gnaphalium supinum. — This plant appears to 

 our view a genuine Antennaria ; notwithstanding the capillary pappus of the 

 sterile flowers; which, although not thickened even in the slight manner of 

 the preceding species, is yet manifestly barbellate (under a lens) towards the 

 apex.
