RAFINESQUIA Neo-Mexicana, Gray, Pl. Wright. 2, p. 2, Фр. 103. Gravelly hills near El 
Раво, etc., New Mexico; Bigelow, Wright, Parry. Cook's Spring ; Bigelow. 
RAFINESQUIA CALIFORNICA, Nutt. in Trans, Amer. Phil. Soc. Т, p. 429. (Тав. XXXIV.) Oak 
groves, Monterey, California; Parry. Found also by Frémont on the Mohave river and in other 
parts of California. Some of the mature achenia (usually the exterior ones) have a mottled ap- 
pearance, as represented in one of the figures. 
CALYCOSERIS PARRYI (sp. nov.): involucro polyphyllo subimbricato ; floribus flavis ; acheniis 
longe rostratis, costis levibus acute trinervatis.—Mountains east of Monterey, California; 
June; Parry. Only а single specimen was gathered, and that consists merely of the upper 
part of the plant, with reduced foliage. It is most interesting, however, as adding a second 
species to the genus Calycoseris, being a strict congener of the New Mexican C. Wrightii. It 
is distinguished by its yellow flowers, rather larger heads, more numerous scales to the invo- 
lucre, of which there are likewise а few external and shorter scales, effecting a transition into 
the smaller calyculate ones, which are more pointed and mostly squarrose-recurved; the 
scales, as well as the peduncles and branchlets, are more conspicuously beset with similar setose- 
pedicellate glands, which here are blackish. More important characters are afforded by the 
achenia; these are more slender and rather longer; the strong ribs are not so thick, and are 
smooth or even, (while in C. Wrightii they are tuberculate-roughened, a character by no means 
sufficiently represented in the plate,) each with a sharp and salient dorsal nerve or keel, and 
with a less conspicuous lateral one on each side ; and the slender beak is as long as the body of 
the achenium.

MALICOTHRIX TENUIFOLIA, Nutt. in Trans. Amer. Phil. Soc. n. ser. 1, p. 435, ex char. Valley 
of the Gila, at Camp Miller ; May, 1855; Schott. The same as Coulter’s No 246, and appa- 
rently Nuttall’s plant. But it is Кш. except perhaps the very base, and the nascent : 
shoots and young involucral scales are canescent with a stellate tomentum, which is soon decid- 
uous. From three to five of the bristles of the pappus are more persistent and naked.
