Low or moist gi-ounds, throughout the Sierra Nevada, from JIariposa Co. north to Washington 

 Territoiy and thence east to Montana. Heads in flower half an inch high, naiTow ; the gohlen- 

 yellow flowers open through the day. Akenes 3 lines and pappus about 4 lines long. The root is 

 said to be eaten raw by the Indians. 



2. M. major, var. laciniata, Gray, 1. c Mostly stouter and more branched 

 from the base, and the leaves in this variety generally pinnately parted into slender 

 linear divisions : involucre of lanceolate and more acuminate scales, which are im- 

 bricated in three lengths, the outermost shortest : bristles of the pappus not quite so 

 plumose as in M. mitans. — Calais {Ptilophora) major, var. laciniata, Gray, PI.

§ 2. Pappus of b to \0 very long-awned scales, either almost plumose or naked: akenes 

 not attenuate toivards the apex and hardly toivards the base : involucre regu- 

 larly imbricated, the outer scales gradually shorter: stems simple or mostly 

 branching : root fusiform and p)robably biennial. — Scorzonella, Gray. 

 {Scorzonella, Nutt., Benth. Calais § Scorzonella, Gray.) 



* ATcenes slender, as in the first section : aw7is or bristles of the pap>p)us barbellate 



or almost plumose, rusty-colored. 



3. M. sylvatica, Gray, 1. c. Stem a foot or so high, rather stout, commonly 

 simple and scape-like, rarely leafy to the middle : leaves laciniate-pinnatitid or 

 toothed : head many-flowered : involucre campanulate ; the scales all acuminate, 

 the outer from an ovate or ovate-lanceolate base : ligides rather long : scales of the 

 pappus 6 to 10 (mostly 10), oblong-lanceolate, considerably shorter than the slender 

 awn. — Scorzonella sylvaiica, Benth. PL Hartw. 320. Ccdais {Anacalais) sylvatica.

Var. Stillmani, Gray, 1. c. Differs in the narrower scales of the involucre, 

 which are lanceolate and gradually tapering from the base, and the awns of the 

 pappus (sometimes at least) less strongly barbellate. 



In woods or low grounds, on the Sacramento and its tributaries, Ilartweg, Bigclmv, &c. The 

 var. collected by Stillman, Samuels, and on Mark West Creek by Bigclow. Peduncle or scape 

 6 to 12 inches long. Head an inch high. Akenes (seen in the mature state only in the variety) 

 3 lines long, glabrous or minutely scabrous. 



* * Akenes mostly shorter {terete, or in one species sometimes more or less i-d-angled) : 



aivns of the pappus only denticulate or scabrous. 

 -f- Scales of the involucre all long-acuminate : pappus of 8 or 10 shoj-t and small 

 entire scales tipped with a very long capillary awn : stems more or less branching 

 and leafy below : ligides elongated. 



4. M. laciniata, Gray, 1. c. A foot or two high, commonly stout : leaves 

 from narrowly to very broadly lanceolate in outline (4 to 16 inches long), commonly 

 laciniate-pinnatifid and the lobes long and slender : heads large : scales of the in- 

 volucre all broad, the outer ovate and abruptly acuminate : scales of the pappus 

 ovate or ovate-lanceolate, only a third or fourth the length of the (sometimes pris- 

 matic) akene. — Hymenonema? laciniatum, Hook. Fl. i. 301. Scorzonella lacini-

Var. procera. Gray, 1. c. Stem stouter and more leafy, 2 or 3 feet high : leaves 

 broadly lanceolate or oblong (1 to 2| inches wide), merely denticulate, occasionally 

 laciniate : scales of the pappus mostly rather narrower or more tapering into the
