Lagophjlla. COMPOSIT.E. 367 



rather firm scarious cup-liko small pappus, its margin ciliate and obscurely fimbriate. Uisk- 

 akencs nearly 2 lines long, oblong-tarbmato, ami witli a broad terminal depressed areola, Imrdered 

 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 pa]>pua to the disk-flowers tiiis species might Ix; sought 

 for in the group to which Blephnripappua 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, heterogamoiis, with about 5 pistillate fertile ray.s, and as 

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

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

 as to completely enclose their obcorapressed akcnea, and commonly 2 or 3 looser 

 and more foliaceous empty exterior ones or bracts, lleceptacle small and flat, 

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

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

 or less obcompressed, obovate-oblong, smooth, nearly straiglit, pointless; tlio.so of 

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

 annuals, of California and Oregon ; with ropentodly brandling 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, Nutt. A foot or two high, at length paniculatcly 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 exsertod, yellow : fertile akenes carinatcly one- 

 nerved down the inner face. — Torr. Sz Gray, Fl. ii. 402. L. ^nininia, 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 : loaves cariy deciduous from the stoma niid tho 

 lit length smooth filiform branches. 



2. L. dichotoma, Bonth. 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 fdiform 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 tho Sacramento and Feather Rivers, ITnrhvrfi, Filch, Jii'jrlmr. Heads larger than in 

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



* * Leaves commonly or mostly opposite : heads nalrd, terminal, slender-pcduncled. 



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

 and witli some small sti[)itate glands : leaves linear ; some nf the lower rnuline 

 sparsely lacnniate-denticulate (2 or 3 ijirlics lonj:) ; ihoso of Ihe branchlot.s short 

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

 exsertod, apiiarontly white. — Pacif P. I^ej). iv. 100, S: Mex. P<mnd. 101. 

 Hemizonia filipes. Hook. & Am., apparently, but the specimens of Pouglns not 

 seen. 



California, Dovglas. On the Sacramento, Fitch, Ncivhcrry, &c. Seemingly a rare species. 

 Akenes not yet known.
