Lagophylla. COMPOSITE. 367 



rather finn scaiious cup-like small pappus, its margin ciliate and obscurely fimbriate. Disk- 

 akenes nearly 2 lines long, oblong-turbinate, and with a broad terminal depressed areola, bordered 

 with the pappus of about 20 equal and rather stout barbate-plumose awns, of fully a line in 

 length. All the outer, and sometimes all but one or two of the inmost disk-akenes are seed- 

 bearing. On account of the anomalous pappus to the disk-flowers this species might be sought 

 for in the group to which Blcpluiripappus belongs, and which it much resembles in the disk- 

 pappus. It really forms a new section in the present genus. 



58. LAGOPHYLLA, Nutt. 



Head several-flowered, heterogamous, with about 5 pistillate fertile rays, and as 

 many hermaphrodite but sterile disk-flowers. Involucre of as many herbaceous 

 scales as ray -flowers, which are flat on the back, with margins at base infolded, so 

 as to completely enclose their obcompressed akenes, and commonly 2 or 3 looser 

 and more foliaceous empty exterior ones or bracts. Receptacle small and flat, 

 bearing a series of 5 or 6 distinct chaffy scales, subtending disk-flowers. Rays cunei- 

 form, palmately 3-cleft or parted : disk-corollas 5-lobed. Akenes of the ray more 

 or less obcompressed, obovate-oblong, smooth, nearly straight, pointless; those of 

 the disk slender and abortive, all destitute of pappus. Soft-villous or hirsute 

 annuals, of California and Oregon ; with repeatedly branching slender stems, alter- 

 nate or opposite mostly entire leaves, and small heads of pale yellow or apparently 

 white flowers. 



* Leaves chiefly alternate : heads leafy-bracteate. 



1. L. ramosissima, jSTutt. A foot or two high, at length paniculately very 

 much branched : lower leaves oblanceolate or linear-lanceolate and somewhat silky- 

 hirsute (an inch or two long) ; the upper and those of the branchlets successively 

 smaller and copiously villous with long and soft hairs, especially along their mar- 

 gins, often becoming concave or involute when dry : heads almost sessile, clustered 

 on the leafy branchlets : rays hardly exserted, yellow : fertile akenes carinately one- 

 nerved down the inner face. Torr. & Gray, FI. ii. 402. L. minima, Kellogg in 

 Proc. Calif. Acad. v. 53. 



Dry hillsides, common through the middle and northern part of the State, and in adjacent 

 parts of Oregon and Nevada. Stems brittle : leaves early deciduous from the stems and the 

 at length smooth filiform branches. 



2. L. dichotoma, Benth. A foot or so high : leaves more strigosely pubescent ; 

 the cauline ones spatulate and often coarsely crenate, those of the branchlets and 

 bracts hirsutely ciliate : heads sessile in the forks of the repeatedly dichotomous 

 almost naked branches, and terminating their filiform peduncle-like extremities : 

 rays much exserted, apparently white : fertile akenes concave and nerveless (but 

 minutely striate) on the inner face. PI. Hartw. 317. 



Plains of the Sacramento and Feather Rivers, Hartiveg, Fitch, Biyelow. Heads larger than in 

 the preceding ; the ligules conspicuous, about 3 lines long. 



* * Leaves commonly w mostly opposite : heads naked, terminal, slender-peduncled. 



3. L. filipes, Gray. A span to a foot high, paniculately branched, soft-villous, 

 and with some small stipitate glands : leaves linear ; some of the lower cauline 

 sparsely laciniate-denticulate (2 or 3 inches long) ; those of the branchlets short 

 (4 to 2 lines long), not ciliate : head small, bractless, on a filiform peduncle : rays 

 exserted, apparently white. Pacif. R. Rep. iv. 109, & Mex. Bound. 101. 

 Hemizonia filipes, Hook. & Arn., apparently, but the specimens of Douglas not 

 seen. 



California, Douglas. On the Sacramento, Fitch, Newberry, &c. Seemingly a rare species. 

 Akenes not yet known.
