 groveSj Monterey, California ; Parry. Found also by Fremont 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 suhimbricato ; floribus flavis ; acheniis 

 longe rostratis, costis Isevibus acute trinervatis. — Mountains east of Monterey, California ; 

 June; Parry. Only a 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 a few external and shorter scales, efiecting 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 

 suflSciently 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.

 rently NuttalPs plant. But it is herbaceous, 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.
