84 PLANTS WRIGHTIAN^. VI. 



uninerviis ; involucre liemisphEerico pauciseriali, squamis lanceolatis acuminatis 

 scarioso-margiuatis ; pappo fusco, fl. fcera. involucro subduplo longiore. — Sandy 

 hills between Cimieluque Springs and the Salado, Chihualiua, April : the female 

 plant. (1402.) — This accords very well with the male plant collected in Mr. 

 Wright's first journey (No. 307) ; but the fertile heads are larger and fuller than 

 the sterile, half an inch in length, many-flowered, and with a copious pappus of a 

 fulvous hue, manifestly inclining to reddish. The scales of the involucre are 3-4- 

 serial, very smooth, with a green centre, and more conspicuous hyaline margins 

 than in the sterile plant. 



B. Wrightii, var. pyrrhopappa : humilis (semipedali), divergenti-ramosissima ; 

 foliis plerisque brevissimis ; pappo fl. foem. rubiginoso vel rubescente involucrura 

 plusduplo superante. — (Xear Mapimi, Durango, Dr. Gregg.) Prairies from Rain- 

 water Creek to Rock Creek, around Prairie-dog towns; June. (1403.) — The 

 fertile plant of the preceding enables me to identify this as a variety of B. Wrightii, 

 of which before the sterile plant alone was known. The mature pappus is half an 

 inch long, of a reddish hue, in Gregg's specimens almost sanguineous. 



Tessaria (Phalacrocline) borealis. Gray, PI. Fendl. p. 75, (§c PI. Wright, p. 

 102. Low banks of the Rio Grande, New Mexico ; May, Nov. (1202.) 



Filagi>;opsis multicaulis, Torr. 8f Gray, Fl. 2. ^j. 263. Rocky hills of the 

 San Pedro, Western Texas ; May. Hills near El Paso ; March, April : a small, 

 vernal form. (1404.) 



Stylocline micropoides (sp. nov.) : pygmsea, albo-lanata ; paleis receptaculi ob- 

 longis basi involutis dorso lanosissimis ; pappi fl. masc. setis Isevibus. — Hills near 

 Frontera, New Mexico; April. (1405.) — A very woolly, small herb, with the 

 habit of a diminutive Micropus erectus, beginning to blossom when only an inch 

 high ; when the stem is terminated by several heads in a glomerate cluster, sur- 

 rounded by linear-lanceolate leaves of 3 or 4 lines in length, similar to the cauliue 

 ones. It soon branches more or less from the base, and is often proliferous from 

 the glomerule. Heads ovoid or subglobose, 2 or 3 lines in length, rather larger 

 than those of S. gnaphalioides, and much more woolly ; the paleae being thickly 

 covered with long and implexed wool, except the scarious tip. These are like those 

 of the Californian species, except that they are narrowly oblong (instead of broadly 

 ovate), and with the lower part, inclosing the flower, contracted and wholly in- 

 folded, instead of having a mere saccate fold in the keel. Receptacle columnar 

 and elongated ; the fructiferous paleae, looking like little pellets of wool, falling 

 away at maturity. Sterile flowers 3 or 4 at the apex of the receptacle, naked, or 

 barely subtended by oblong and glabrous paleae ; the abortive ovaries furnished with 

 a very fugacious pappus of three or four slender and smooth, slightly clavellate 

 bristles. Anthers caudate. Achenia obovoid-oblong, slightly compressed, nearly 

 straight. — A true congener of S. gnaphalioides. I see nothing to separate it, nor 

 the other Evacoid genera, from the Gnaphaliese. 



DiAPERiA PROLiFERA, Nutt. / TovT. Sf Gray, Fl. 2. p. 264. Stony hills of the 

 Pecos ; May. (1406.) — A very depressed form. 



BoRRicHiA FRUTEscENs, J)C. Bauks of the Pccos ; June: in patches. (1407.)
