On tlic Faralloiias, ronky islets ofT San Francisco, Afr. Gruhcr. Tlie rays in the specimen do 

 not exceed tlie disk, but, being broad and flat, probably tliey may become more conspicuous.

Valley of the Sacramento (Fremont, Hartior.g) and near Vallejo, Greene. Ovaries minutely 



f)nbc9ccnt, or, in the form from Hartweg, without pappus, glabrous ex(;cpt at the summit. Upper 

 eaves inclined to bo dilated bolow, nnd to have 3 to 5 palmiitcly-disposed lobes. 



8. B. Tlliglnosa, Oray, 1. c. Diffuse, at length decumbent, a span to a foot high, 

 loosoly pubescent with eomowhat cobwebby hairs: lower or most of the leaves 

 copiously pinnatilid from a broad or broadish rha(dua ; the lobes narrowly linear : 

 scales of the involucro nnd oblong oxserted rays usually 10 to 13 : throat of disk-

Var. tenella. Gray, 1. c. (Dichu'ta tene/la, Nutt. 1. c), is only a depauperate 

 state, on drier .soil, with narrow linear leaves, and more of them entire ; the rays and 

 involucral scales reduced to 8 or 9, or rarely to 5 or G, 



Low grounds, common through tlie western i)ai-t of the State. Very variable. Leaves in the 

 larger plants a span long, and the stems luxuriant in proftortion. Akenes a line long, oblong- 

 linear and a little narrowed downward, sometimes pubescent, sometimes glabrous, apparently in 

 plants growing together. 



68. ACTINOLEPIS, DC, Benth. 



Head many-flowered, with few or numerous pi.stillato rays ; all the flowers fertile. 

 Involucro campaiuilato, of a single series of oblong or lanceolate thin-herbaceous 

 scales, which become concave or involute and embrace more or less the ray-akencs. 

 Receptacle naked, convex or conical, or in an ambiguous species flat. Rays oval or 

 oblong, 2 - 3- toothed : disk-corollas with narrow tube and carapanulate 6-lobed 

 limb. Anthers tipped with an abrupt narrowisli or very slender appendage. Style- 

 branches with a truncate-capitate (or rarely conical) tip. Akenes linear and mostly 

 tapering to the base, or linear-cuncate ; tliose of the my commonly somewhat in- 

 curved. Pappus a series of chalfy scales or squamellrc (either few or numerous), 

 which are either pointless or extended into an awn, or sometimes none. — Low and 

 difl'use or depressed annuals, all of the Californian region, mostly woolly, in one 

 section glandular; with opposite or alternate commonly toothed or pinnately-partcil 

 leaves, and small or proportionally rather large lieads terminating tlie branches. 

 Flowers all yellow, or the rays occasionally white or rose-color. — Gray in Proc.

A rather well-marked genus, as rightly characterized on the original species by Torrey and 

 Gray, now hapi)ily extended by ncntliam' in the Gcnci-n rinntnnim, nnd still more nuRmented in 

 the paper rofened to above. The section placed foremost resembles H'lTin, section Dic/uitn fnym 

 which it is distinguished by the partial enclosure of the rnyakcncs iu the si-nles of the mvolucrc.
