LagophyUa. COMPOSITE. 367 



rather firm scarious cup-like small pappus, its margin filiate and obscurely fimbriate. Disk- 

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

 with the pappus of about 2i> 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. < in account "I the anomalous pappus to the disk-flowers this species might besought 

 for in the group to which Ulc/jlwri/>iiji/ins 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, hcteroganious, 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 liliaceous empty exterior ones or bracts. Eeceptacle 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 mow; 

 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 tlowers.

1. L. ramosissima, Nutt. 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 fare. — Torr. & Gray, Fl. ii. -102. L. minima, Kellogg in

Dry hillsides, common through the middle and northern part of the State, and in adj.-i.-.-nl 



part- of gun and NVvada. Stems brittle: leaves early deciduous from the stems and the 



a1 length smooth filiform branches. 



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



the cauli tes spatulate and often coarsely crenate, those of the branchlets and 



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

 almosl uaked 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. — PL Hartw. .">I7.
