alveolate. Anthers included, tipped with a setaceous-subulate ujjpendage. Branches 

 of the style tipped with a very short and obtuse or truncate appendage which is 

 thickly covered with hispid bristles in a tuft, and often with a central cusp, or else 

 with a longer subulate and less strongly hispid appendage. Akenes all fertile, 

 silky-villous, turbinate or cuneiform, more or less compressed. Pappus simple, 

 mostly shorter than the corolla (especially in the marginal flowers), of numerous 

 miocpml rij^id Bcabroua bristlos, usually turning roddisli-hrown. — Annual or bien- 

 nial {probably never truly perennial) lierbs, all Californian, with slender branches, 

 clothed (at least when young) with flocculent more or less deciduous wool. Leaves 

 alternate, thickish, those of the branches sessile. Heads rather small. Flowers in 

 the original species yellow (sometimes turning purple in age), in most if not all the 

 others blue-purple or white. (Nerves of the corolla-lobes deejjly intramarginal, the 

 aestivation induplicate up to the nerve.) — Cham, in Linna?ii, iv. 203; Gray in 

 P>puth. n. Hartw. 315, in Proc. Am. Acad. vii. 351, & viii. 634. 



§ 1. Liinb of the corolla more or less obliquely or imlmniely b-parted, at least in the 

 marr/inal flowers : branches of the style very obtuse and toith a brtish-like tuft 

 of bristles, in which the minute setiform appendage (ivhen there is any) is 

 nearly hidden. • 



1. L. G-ermanorum, Cham. Low, much branched, spreading on tlie ground, 

 at first whitish-tomentose, soon greener: lower leaves spatulatc and ])innutilid ; the 

 upper oblong or linear and 8])aringly incised or toothed, or on the brancidots small 

 and brnct-like, and occasionally granulosc-glandular, as are the spreading green tips 

 of the involucre : heads terminating slender divergent branchlets, 15 - 25-llowered : 

 corollas yellow, the marginal ones conspicuously enlarged, palmate and forming a 

 kind of ray, their stamens sometimes abortive. — Torr. Bot. Wilkes Kxp. 33G, t. 7, 

 (style wrongly delineated.) 



Hillsides and open grounds, rather abundant from San Diego Co. to San Francisco. Head with 

 flowers expanded about halt' an inch in diameter, the larger and pahiiate marginal corollas form- 

 ing a Ccntaurea-\ike ray. 



2. L. ramulosa, Gray. Erect and diffusely paniculato-branched, a span to a 

 foot or two in height, white-woolly, becoming naked and usually glandular with 

 age : cauHne leaves oblong or lanCQolate, thickish, entire or serrulate ; those of the 

 branches small, ovate or oblong, closely sessile by a cordate partly clasping base, 

 gradually reduced to minute bracts : heads terminating slender diverging branchlets, 

 10 — 20-flowered : scales of the involucre acute and the greenish tips appressed : 

 corollas violet-])urple, tlie marginal ones a little enlarged and slightly oblique. — PI.

Plains, &c., from near San Francisco to Mendocino Co. Heads rather snialler than of the 

 preceding. A slender and dilfnso form, with sniiiller h<'ads (vnr. tenuis), occurs frorn Monterey ? 

 {Doiiglns) to I'eru Cieek, at 5,100 feet, llothrtx-k. 



3. L. nana, Gray, 1. c. Dwarf and depressed, 1 to 3 inches high, very woolly : 

 simi)le or clustered stems thickly beset with the spatulato or lanceolate? entire lejive^: 

 heads terminal and axillary, closely sessile, 10 - 12-flowered : scales of the invo- 

 lucre linear-lanceolate, chartaceous and with scarious margins; the iniiormost con- 

 spicuously acuminate, almost cartilaginous when dry, equalling the disk : cor<>IIa.s 

 (apparently purplish) little exsortod, mostly regularly Hlobed. — Bot. Wilkes Kxp.

On the Sacramento, Dr. Pickrrinci, Pcv. Mr. Fitrh. Foot-liills of tlir so»ithcrn Sierra Nevnda, 

 J. Muir, Dr. Rothrock. A singuhir little plant, with the lirnds r.mipnratively large, i. e. hnlf an 

 inch long ; the purple pappus nearly equalling the corollas, and coiisi)icuou8ly contrasting with 

 the white wool. It is poorly figured in the work referred to.
