COMPOSITE, 437 



almost diiFusely brauchiug, the many and not elongated peduncles form- 

 ing a corymbose top to the herb as a whole: leaves narrow, entire, divar- 

 icately spreading, not dilated or manifestly connate below: heads ^4 in. 

 wide — Abundant on low plains, and even moist slopes of hills. Much 

 more common than the last, and confounded with it for many years by 

 Gray. May, June. 



4. L. chrysaiitha, Greene, Man. 204 (1894), and Bull. Calif. Acad. i. 

 93 (1885), under Crockeria. Habit, foliage and flowers of the last, but 

 plant smaller: achenes obovate-oval, much compressed; surrounded by

 Joaquin in Tulare Co, Greene. April. 



5. L. conjugens, Greene, Pittonia, i. 221 (1888). Only a few inches 

 high; leaves narrowly linear, only the lowest entire, the others cleft into 

 several pairs of long linear segments, these entire or toothed: involu- 

 cral bracts united below the middle only; achenes very small (1 line 

 long) olive-green and polished: pappus none. — Subsaline soil near 

 Autioch; closely connecting this genus and the following. April, May. 



74. BAEKIA, Fischer ct Meyer. Plants mostly annual, with oppo- 

 site leaves, and middle-sized heads on slender peduncles; the herbage 

 usually pubescent, but only sparingly so, never hoary or tomentose. 

 Bracts of the campanulate involucre uniserial or nearly so, and distinct, 

 usually carinate below. Rays few or many often short. Achenes cla- 

 vate linear or linear-cuneiform. Pappus of few awns or palese, or both, 

 or occasionally none. 



* Pubescence hirsululoiis; leanes entire or merely toothed; receptacle 



conical; pappus arisliform or wanting. — Baeria proper. 



■i— Root perennial; pappus none. 



1. B. maeraiitha, Gray, Proc. Am. Acad. xix. 21 (188S); Greene, 

 Man. 205 (1894), under Lasthenia. Perennial, stout and nearly simple, 

 decumbent at base, with peduncles 4 — 8 in. long: leaves somewhat 3- 

 nerved and obtuse, linear, 4—8 in. long, hispid-ciliate toward the base: 

 heads % ^^- liigh and as broad: involucre of about 12 hirsute-pubescent 

 thickish herbaceous bracts: ligules 3^^—34 in. long. — Moist lowlands of
