SUNFLOWER FAMILY. 449 



part puberulent only above and the leaves merely finely eiliate; lower leaves 

 pinnately parted or lobed, upper entire; aehenes villous-pubescent or partly 

 glabrate; ehaffy bracts to most of the disk-flowers as also in the next; pappus 



of about 10 to 18 unequal and rigid subulate awns, which are somewhat 

 scabrous or slightly hirsute near the dilated base, the marginal ones rather 

 shorter than the corolla, the smaller hardly half as long. — (Calliglossa douglasii 

 li. & A. Blepharipappus douglasii Greene.) 



Common around San Francisco Bay. Var. oligochaeta Gray. Leaves less 

 lobed; pappus of only 2 slender (and often short) marginal awns or with 

 some intervening rudiments. — Conn Valley, Napa Co.; Santa Rosa. May. 

 (Blepharipappus douglasii Greene var. oligochaetus Greene.) 



11. L. fremontii (T. ».\; G.) Gray. About 1 ft. high, minutely pubescent; 

 Leaves mostly pinnately parted, not eiliate; pappus-paleae ovate- to oblong- 

 lanceolate, tapering into a subulate awn, nearly equaling the corolla, the margin 

 entire, accompanied by some long-villous free hairs. — (Blepharipappus fre- 

 montii Greene.) 



Upper Sacramento Valley southward to the San Joaquin. 



12. L. nutans Jepson, n. comb. Low, 5 to 7 in. high, the branches slender 

 and divergent; herbage hirsute, especially the leaves, the stems reddish brown; 

 Leaves linear, all entire, the lower pairs opposite; peduncles somewhat stipitate- 

 glandular; heads erect in flower, nodding in bud and fruit; rays 5 to 7, yellow, 

 2% to o l / 2 lines long; aehenes l'o lines long, hispidulous; pappus-bristles nar- 

 rowly lanceolate, acuminate, 8 to 10, unequal, with barbellate margins. — (Ble- 

 pharipappus nutans Greene.) 



Mountain slopes: Xapa Range; Mt. Hood Range. May. Excellent species. 



53. LAGOPHYLLA Nutt. 



Soft-villous or hirsute annuals with rigid and brittle stems, in ours usually 

 becoming naked below by the early falling of the lower leaves. Leaves alternate 

 or the lower opposite, mostly entire. Flowers pale yellow. Heads small, sub- 

 tended by foliaceous bracts. Bracts of the involucre 5, thin-herbaceous, flat 

 on the back, with margins at base infolded and completely enclosing an 

 obcompressed achene, with which it is deciduous. Receptacle small and flat, 

 bearing about 5 perfect disk-flowers, these surrounded by a single row of dis- 

 tinct chaffy bracts. Rays cuneate, palmately 3-cleft. Ray-achenes obcom- 

 pressed, obovate-oblong, smooth, nearly straight, pointless; disk-aehenes slender, 

 sterile. Pappus none. Bracts and glabrous aehenes all deciduous at maturity. 

 (Greek lagos, a hare, and phullon, leaf, the upper leaves sometimes copiously 

 villous on the margin.) 



1. L. ramosissima Nutt. Stem simple, at length paniculate] v very much 

 branched; leaves (especially the upper) silky-hirsute with soft hairs, the short 

 - subtending the heads densely villous-eiliate ; lower leaves oblanceolate or 

 Linear-lanceolate, often narrowed at base to a slender petiole, 1 to 2C in. long, 

 often becoming concave or involute when dry; heads almost sessile, crowded on 

 the leafy branchlets; rays barely exserted, pale yellow; fertile aehenes cari- 

 nately 1-nerved down the inner face. 



Common on dry hills and plains in the Coast Ranges (Solano Co., Napa 

 Valley, Eealdsburg, Alameda Co.), Sierra Nevada foothills and Southern 

 California. Var. congests Jepson. Robust, nearly simple, very short 

 branches, 1 to l'_. ft. high or much branched and nearly :i ft. high; heads 

 larger, in thick glomerules. — North (oast Ranges: Mt. Tamalpais; Pleasant 

 Valley, Solano ( o. ; Lake < 'o.
