406 DESCRIPTIONS OF NEW SPECIES 



scariose and smooth, sublanceolate, acute. — (3. * tomentosa; leaves crowded and 

 tomentose, flower clusters approximating in spikes. 



Hab. Near St. Barbara, Upper California. Nearly allied to F. montana, but with larger 

 capituli, &c., in /3. the scales of the involucrum are brownish and purple. A much branched annual, 

 about a span high. External florets, without pappus. 



ANTENNARIA. (R. Brown.) 

 Anteiinaria pJantaginea. 



Hab. On the plains of the Platte to the "Black Hills." A one-flowered variety of this species 

 sometimes occurs, as in the A. monocep/iaht, of Decandolle, which is also, probably, a similar 

 variety of .4. alpina. Specimens have been sent to me from Louisiana by Professor Carpenter, 

 and more recently they have been found on the Wishahickon, by jMr. C Lea, Junior, of Phila- 

 delphia. In these specimens the solitary liead of both sexes is unusually large, and the leaves very 

 broad. 



Antennaria ^paj-vifolia; subctespitose, with procumbent sarments; stem sim- 

 ple; lower leaves spathulate, or spathulate-linear, the upper linear, all whitely 

 tomentose; flowers conglomerate; scales of the involucrum oblong-ovate, eroded, 



yellow. 



Hab. On the Black Hills and plains of tlie upper part of the Platte. A dwarf species, spreading 

 out in canescent tufts with very small leaves, which are about half or three quarters of an inch 

 long, and about two or three lines wide; the flowers in an irregular, somewhat round mass, not 

 a circular corymb, with the scales of the corymb sulphur yellow, and very conspicuous. Radical 

 leaves somewhat rhomboidally spathulate. The pappus of the male flower is very conspicuously 

 clavellate: the female flower has purple oblong-lanceolate scales to the involucrum, and a liliform 

 pappus. A specimen of this sex from Altai lias a near resemblance to our plant, but is larger in all 

 its parts, and is the A. hyperborea of Don. 



Anteimana * Lahradorica; canescently tomentose; sarments procumbent, 

 flowering; stem simple; radical leaves spathulate-linear, cauline linear, sessile, 

 at length nearly smooth; capituli pedicellate in a cyme of three to five; scales 

 of the involucrum ustulate and brownish, lanceolate and long acuminate, mem- 

 branaceous. 



Hab. Labrador. (Herb. Schweinitz.) Apparently a very distinct species. At tirst glance 

 resembling A. alpina, but more nearly allied to A. pluntaginea; it is, however, a much smaller plant, 

 the leaves not three-nerved; the scales of tlie involucrum brown, and as it were soiled at the tips, 

 which are very much acuminated ; the achenium is also perfectly smooth ; with the pappus thick- 

 ened at the base, somewhat scabrous, and yellowish white.
