From Sonoma county to the borders of Oregon. 



S. PEATENSis. — Leafy at base only, the scapose peduncles 

 2 feet high: leaves linear, lanceolate, long-cuminate, entire, 

 a foot long: heads an inch high and nearly as broad; bracts 

 16 — 20 in 3 series, ovate — to lanceolate — acuminate: akenes 

 2 lines long; pappus white, 4 lines, the triangular-ovate 

 palea J line. 



Sunny and rather moist meadow lands at Yreka, in the 

 northern part of the State, collected by the writer June 21, 

 1876, and distributed by him under number 883 as Microseris 

 laciniata var. lorocera. It is readily distinguishable from 

 the preceding and the following by its long, scapose pe- 

 duncles, and narrow, entire, long, slender-pointed foliage. 



S. LACINIATA, Nutt. — Stem less robust and more branch- 

 ing and leafy than in the last : leaves pinnately parted, the 

 segments narrowly linear, an inch or more long: heads a 

 half inch high; bracts 16 — 20, from round-ovate to lanceo- 

 late, all abruptly acuminate: akene 2 lines long: pappus 

 white, about 3 lines, the ovate-lanceolate palea less than a 

 line.— Trans. Am. Phil. Soc. P vii, 426: Torr. & Gray, Fl. 

 ii. 470. Microseris, Gra^^, 1. c. 



Northern borders of California to the confines of British 

 Columbia. 



S. LEPT03EPALA, Nutt., 1. c. — Bracts of involucre in 2 dis- 

 tinct series, the ovate outer ones 5 or 6 only, and hardly 

 more than calyculate to the numerous, lanceolate inner ones, 

 akenes, white jDappus, etc., in all their parts more elongated 

 than in the last species; foliage less divided, often merely 

 toothed. Torr. and Gray, 1. c. ; Microseris, Gray, 1. c. 



Same range as S. laciniata, from wdiich it differs very ob- 

 viouslv in the character of the involucre.
