324 COMPOSITE. Monolopia. 



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

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

 M. bahiaefolia, BEXTH. Smaller than the foregoing, and with similar floccnleut tomen- 

 tum ; the simple monocephalous steins 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 akeues sparsely pubescent. PI. Ilurtw. 317 ; Gray, 

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

 specimens. 



139. Li ASTHENIA, Cass. (Aao-OevLa, 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. oibtusifolia 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. -- Rancagua, Ptepp. & 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 puberuleut oblong- 

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

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

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



2. HoLOGfMNE. 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. Xant/io, Rerny, in Ann. Sci. Nat. ser. 3, xii. 101. Lasthenia, 

 Lindl. Bot. Reg. 1. c. 



L. glabrata, LIXDL. 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 : akeues narrowly obovate-oblong with acutish edges, smooth and 

 glabrous. DC. Prodr. v. 665; Hook. Bot. Mag. t. 3730 ; Torr. & Gray, I.e. L. glabrata 

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

 Liudl. Bot. Reg. t. 1780, 1823. Hologymne rjlabrato, Bartl. ]. c. Monolopia glabrata, Fisch. 

 & Meyer, Sort. Petrop. 1835. Moist grounds throughout W. California. 



Var. Coiilteri. A smaller form : akeues smaller and narrower, with obtuse edges, 

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

 338), Brewer, Cleveland, Prinyle. 



140, BURRIEL.IA, 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. G64 ; 

 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.
