the persistent vestiges of former leaves. The foliage, like the stems, is uniformly whitened 

 with a thick and closely appressed silky-hirsute pubescence ; the lowest leaves an inch or 

 more in length, including the long tapering base or petiole, the upper shorter, more ses- 

 sile, and nearly linear, less than a line in width. Head, rays, &c, very like those of E. 

 pumilum. Scales of the involucre somewhat in two series, almost equal. Inner pappus 

 of rather copious, strongly scabrous bristles. — This striking species should probably rank 

 with E. pumilum and E. concinnum in the section Stenactis, Torr. &• Gray, I. c, rather 

 than in Pseuderigeron.* 



/ 333. E. ciNEREUM (sp. nov.) : bienne? undique niolliter cincreo-pilosum ; caule e 

 basi ramoso ; ramis adsurgentibus apice longe nudis monocephalis; foliis spathulatis vol 

 lineari-oblongis basi attenuatis integerrimis seu radicalibus paucidentatis incisisve ; ligulis 

 numerosissimis gracilibus (albis nunc purpurco tinctis) involucrum hirsutum duplo super- 

 antibus ; pappo radii et disci conformi duplici, exteriore coroniformi-squamellato, interiore 

 e setis sub-20 fragilibus deiiduis. — Var. a. is a dwarf, vernal form, only a span high, 

 quite hoary, the primary flowering stems erect and almost scapiform (no. 374 of the dis- 

 tribution). Dry, exposed places around Santa Fe ; May. Var. /3. has taller and more 

 diffuse stems (10 inches high), the leaves almost lanceolate, entire, the lower tapering 

 into slender petioles. Low, sandy banks of the Rio del Norte and of Santa Fe Creek ; 

 May to June. (380.) Var. y. is a larger, coarser, and much more leafy state ; from the 

 valley of Santa Fe Creek, near irrigating ditches ; May to July. (385.) — The heads 

 are as large as those of Bellis perennis, solitary on peduncles, or the naked summit of the 

 stems, of from 2 to 4 inches in length. The species belongs to the first division of the 

 section Phalacroloma, Torr. #• Gray, I. c.f Some forms of this, or of an allied species 

 (possibly E. affine, DC), with rather less numerous and white rays, and either entire or 

 incised leaves, were gathered at Buena Vista and Encantada by Dr. Gregg. 



334. E. flagellare (sp. nov.) : bienne ? striguloso-puberulum, pumilum ; caulibus 

 gracillimis e basi ramosis, floriferis seu primariis simplicibus superne aphyllis monocepha- 



* A Texan species which I refer to the same section is probably Distasis modesta, DC, although the 

 squamellre and fragile setce of the pappus are more numerous than in De Candolle's character. 



Erigeron modestum : hirsuto-pubescens, cinereum ; caule ramosissimo panictilato-corymboso ; ramis 

 monocephalis ; foliis subspathulatis linearibusve basi attenuatis imis petiolatis integerrimis ; ligulis 30 -40 uni- 

 serialibus (albis) involucrum canescenti-hirsutum duplo superantibus ; acheniis parce pilosulis; pappo radii et 

 disci conformi duplici, exteriore paleaceo-squamellato, interiore e setis fragilibus circiter 12. — Disiasis mo- 

 desta, DC. Prodr. 5. p. 279 ? — New Braunfels, Texas, Lindheimer. 



t From Mr. Lowell's herbarium I find that Dr. Gambell gathered the same species in the vicinity of 

 Santa Fe.
