324 composite. 



var. pinnatifida, Gray, Bot. Calif, i. 383. — Foothills of the Sierra Nevada, California, from 

 Calaveras to Tulare Co., Heermann, Pratten, Congdon. Also near Auburn, Bolander. 

 M. bahiSBfolia, Benth:. Smaller than the foregoing, and with similar floccnlent tomen- 

 tum ; the simple monocephalous stems only 2 inches high : leaves small (at most half-inch 

 long), spatulate to linear, entire, or lower ones 3-lobed : head hardly 3 lines high : involucral 

 bracts distinct to the middle : immature akenes sparsely pubescent. — PI. Hartw. 317 ; Gray, 

 Bot. Calif, i. 383, excl. var. — Valley of the Sacramento, Hartweg. Probably depauperate 

 specimens. 



139. LASTHENIA, Cass. (AacrOevia, a courtesan, who was a pupil of 

 Plato : name given, by some freak of the founder, to a genus of three Western 

 American plants.) The Chilian L. obtusifolia has comparatively few-flowered 

 nearly or quite homogamous heads, and a less developed receptacle. — Low and 

 slender annuals, mostly quite glabrous and slightly succulent ; with opposite and 

 linear or narrowly lanceolate mostly entire leaves, their sessile bases connate 

 round the stem ; the yellow-flowered heads pedunculate, terminating the stem and 

 branches. — " Opusc. Phyt. iii. 88 " ; DC. in Lindl. Bot. Reg. t. 1780, 1823, & 

 Prodr. v. 664 ; Torr. & Gray, Fl. ii. 377. 



§ 1. Lasthenia proper. Pappus paleaceous : heads discoid; the ligules not 

 surpassing the involucre or the short glabrous disk-corollas, therefore wholly 

 inconspicuous. — Eancagua, Poepp. & Endl. Nov. Gen. & Spec. i. 15, t. 24, 25. 



L. glaberrima, DC. 1. c. Somewhat fleshy : stems ascending, a span to a foot long : heads 

 on long peduncles which are enlarged at summit, nodding after anthesis : leaves elongated- 

 linear : involucre about 15-toothed : corollas all shorter than the minutely puberulent oblong- 

 linear akenes : pappus of 5 to 10 rigid paleas, two or three of them with subulate or shorfc- 

 awned points, the others erose or laciniate. — Torr. & Gray, 1. c. ; Gray, Bot. Calif, i. 384. — 

 Wet meadows near brackish water, along the coast of California and Oregon. 



§ 2. Hologymne. Pappus wanting: rays large, conspicuously exserted: 

 disk-corollas fully as long as the akene ; their lobes sparsely papillose-barbellate 

 outside, as in Monolopia. — Gray, Bot. Calif. 1. c. Hologymne, Bartl. Ind. Sem. 

 Goett. 1837, 1839. Xantho, Remy, in Ann. Sci. Nat. ser. 3, xii. 191. Lasthenia, 

 Lindl. Bot. Reg. 1. c. 



L. glabrata, Lindl. Somewhat fleshy, sometimes slightly pubescent: stems erect: leaves 

 shorter : peduncles somewhat enlarged under the erect head : involucre more hemispherical : 

 ligules 3 to 6 lines long : akenes narrowly obovate-oblong with acutish edges, smooth and 

 glabrous. — DC. Prodr. v. 665; Hook. Bot. Mag. t. 3730; Torr. & Gray, 1. c. L. glabrata 

 & L. Californica (a smaller form, mistaken for preceding species which DC. had so named), 

 Lindl. Bot. Eeg. t. 1780, 1823. Hologymne glabrata, Bartl. 1. c. Monolopia glabrata, Fisch. 

 & Meyer, Sert. Petrop. 1835. — Moist grounds throughout W. California. 



Var. Coulteri. A smaller form: akenes smaller and narrower, with obtuse edges, 

 sprinkled with minute rough points or glands. — Saline marshes, S. California, Coulter (no. 

 338), Brewer, Cleveland, Pringle. 



140. BURIIIELIA, DC, partly. (Andres Marcos Burriel, a Spanish 

 Jesuit and historian, who, in 1758, wrote a History of California, and edited the 

 account by Venegas of the establishment of its missions.) — Prodr. v. 664 ; 

 Benth. & Hook. Gen. ii. 398 : now reduced to one of the three original species. 

 Perhaps too near the following somewhat earlier-published genus. 



B. microglossa, DC. 1. c. Slender annual, a span high, hirsute : leaves an inch long and 

 barely a line wide, entire : involucre 3 lines high, equalling the yellow flowers. — Low ground, 

 from San Francisco Bay to San Bernardino, California ; fl. spring ; first coll. by Coulter and 

 Douglas.
