FLORA. 



the long, very narrow base which is about as long as the expanded portion, 

 strongly 3-nerved, and usually with an additional pair of lateral nerves, densely 

 tomentose beneath, dull green and loosely floccose above; pistillate heads rather 

 numerous, corymbose; involucre about 7 mm. high, its bracts linear to linear- 

 lanceolate, brown below, the inner acuminate; stem of staminate plant 1-1.5 dm. 

 high, the heads small, glomerate. 111. and Mo. to La. The basal leaves of a plant 

 evidently closely related to this were collected by Mr. Bicknell at New York and 

 by Mr. Pollard at Washington. 



IO. Antennaria fallax Greene. TALL CAT'S-FOOT. Stolons rather stout, 

 often I dm. long, leafy. Scape of fertile plant 3.5-4.5 dm. tall, stoutish; basal 

 leaves oval to obovate, 6-10 cm. long, 2-4 cm. wide, acute or obtuse, contracted 

 gradually into a narrow base about as long as the expanded portion, dull green and 

 loosely floccose, or at length glabrous above, densely white- tomentose beneath; 

 stem-leaves lanceolate, rather distant, acuminate, 2.5-5 cm. long; heads capitate 

 to corymbose; involucre 8-10 mm. high, its inner bracts attenuate-acuminate, the 

 outer oblong, obtuse; staminate plant very much smaller. In dry soil, Me. to D. C., 

 Wis. and Kans. April-May. 



xi. Antennaria Farwellii Greene. FARWELL'S CAT'S-FOOT. Closely resem- 

 bling the preceding species, sometimes lower. Stolons rather stout, leafy; basal 

 leaves spatulate to obovate-spatulate, obtuse, the expanded portion usually larger 

 than the gradually narrowed base, dull green and floccose or becoming glabrous 

 above, strongly 3-nerved, 4-8 cm. long, 2.5 cm. wide, or less ; heads capitate to 

 subcory mbose ; involucre 810.5 mm. high, its inner bracts acute, obtusish, or a 

 few of them acuminate. Me. to Mich. May-June. 



12. Antennaria Parlinii Fernald. PARLIN'S CAT'S FOOT. More or less 

 glandular-pubescent; stems of fertile plant 3-4.5 dm. tall. Leaves bright green 

 and devoid of tomentum on the upper surface from the time of unfolding, or very 

 slightly floccose when very young, the basal ones obovate or spatulate to elliptic, 

 obtuse or acutish, gradually contracted into a narrow base about as long as the ex- 

 panded part, 5-8.5 cm. long, 2-3.5 cm - wide; stem-leaves lanceolate or ; the lower 

 narrowly oblong; heads corymbose; involucre about 8 mm. high, its bracts all 

 lanceolate-acuminate or the outer ones linear-oblong and obtusish. Me. and Vt. to 

 N. J. and D. C. May-June, 



13. Antennaria ambigens (Greene) Fernald. INTERMEDIATE CAT'S-FOOT. 

 Similar to A. fallax, and perhaps only a glandular form of that plant. Stem not 

 so tall, its leaves rather closer together, usually glandular only above; basal leaves 

 sometimes not over 2.5 cm. long; inner involucral bracts of the fertile heads acumi- 

 nate. Me. to D. C. 



14. Antennaria alpina (L.) Gaertn. ALPINE EVERLASTING. (I. F. f. 3843.) 

 Surculose by short stolons; stems floccose-woolly, 3-10 cm. high. Basal leaves usu- 

 ally numerous, spatulate or linear-oblong, obtuse, silvery-woolly on both sides, or 

 glabrate and green above, 8-25 mm. long; stem- leaves linear and small, few; 

 heads in a terminal capitate, or seldom somewhat corymbose cluster, rarely soli- 

 tary, 4-5 mm. broad; involucre about 5 mm. high, the bracts of the fertile heads 

 dark brownish green, the inner ones acute or acuminate; those of the sterile heads 

 lighter, brownish, broader and obtuse; achenes glandular. Lab. and arctic Am. to 

 Alaska. The Rocky Mountain plant referred to this species is A. media Greene. 



15. Antennaria dimorpha (Nutt.) T. & G. Low EVERLASTING. (I. F. f. 

 3849. ) Tufted from a thick woody often branched caudex, 3-4 cm. high. Leaves 

 all in a basal cluster, spatulate, white-canescent or tomentose on both sides, obtuse 

 or acutish, 1-2.5 cm< l n g> 2 ~4 mm - wide, narrowed into short petioles; heads of 

 staminate flowers about 6 mm. broad and high, solitary and sessile among the 

 leaves, or raised on a very short sparingly leafy stem, with obtuse or obtusish 

 brownish involucral bracts, those of pistillate flowers longer, their inner bracts lin- 

 ear-lanceolate, acuminate; pappus of the staminate flowers slender, scarcely thick- 

 ened, but barbellate at the tips, that of the pistillate flowers of fine and smooth bris- 

 tles. Dry soil, Neb. to Utah and Cal., north to Mont, and Br. Col. April-June. 



44. ANAPHALIS DC. 



Perennial white-tomentose or woolly herbs, with leafy erect stems, in our spe- 

 cies, alternate entire leaves, and small corymbose discoid heads of dioecious flow-
