422 COMPOSITE. 



nor hispid, the loosely thyrsoid-pauicled branchlets with scattered 

 smallish white-rayed heads: floral leaves not crowded, very narrow, re- 

 curved, hispid-ciliate and gland tipped: teeth of the cup of the recept- 

 acle also gland-tipped: rays 3, their obovate-triquetrous smooth achenes 

 hirsutulous on the angles and around the summit: disk-achenes also 

 angular, strigose-pubescent throughout, with 5 linear abruptly acute 

 palese of their own length, and as many linear-acuminate ones twice as 

 long. — Plains about Stockton; collected only by Dr. Parry. 



8. C. villosa, DC. Prodr. v. 695 (1836). Simple or sparingly branch- 

 ing, 1 — 2 ft. high, somewhat villous-pubescent, the margins of reduced 

 leaves and bracts villous-ciliate: heads mostly solitary and subsessile in 

 the axils of the scattered leaves: bracts or chaff of the involucre acute, 

 not gland-tipped, only slightly united and that toward the base: rays 

 3—5, white; their achenes broad and truncate at summit, where they are 

 also conspicuously villous; those of the disk-flowers villous-hairy on the 

 angles and also at summit, bearing a pappus of 10 subequal linear-sub - 

 iilate, long palefe. — Hills along and near the seaboard in Monterey and 

 San Luis Obispo counties; in recent years collected by Hickman, 

 Norton, Palmer. 



9. C. cephalotes, DO. 1. c. Seldom more than a foot high, simple or 

 variously branched, pubescent, the leaves with hirsute margiu, the floral 

 more or less glandular: heads very narrow and densely glomerate termi- 

 nally and in the axils of the upper leaves; the narrow cup of the recep- 

 tacle acutely about 5-toothed and decked exteriorly with small stalked 

 glands : rays 1 or 2, or in some heads none, their achenes tuberculate, 

 prominently but obtusely angled, minutely hispidulous at summit and 

 occasionally upon the angles: disk-achenes 5-angled, canescently stri- 

 gose, most of the pappus-palese ovate-lanceolate and aristate-pointed, 

 little longer than the achene, but 2 or 3 short and blunt. — Hills of Marin 

 and Sonoma Coviuties. Pleasantly balsamic-scented. Species perhaps 

 including the obscure and only partly described C. multiglandulosa, DO. 



10. C. splcata. Hemizonia spicata, Greene, Bull. Torr. Club, ix. 16 

 (1882). Slender, 1 — 2 ft. high, floriferous throughout, the heads glom- 

 erate-spicate, subsessile in the axils of all the leaves: floral leave-* terete 

 and glabrous except at the dilated and ciliate base, all truncate and sur- 

 mounted by a large stalked gland: ray-flowers 1 or 2, their achenes obo- 

 vate and scarcely angled, canescently villous witli appressed hairs: those 

 of the disk also canescent, but less so, crowned with a pappus of 10 

 subulate awn-pointed palese. — Lower foothills of the mountains in Cal- 

 averas Co., about Milton, where it was collected, first by Dr. Parry, in 

 1881, and again by the author, in 1889; not otherwise known.
