324 COMPOSITiE. Monolopia. 



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. bahisefolia, 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, Ilartweg. Probably depauperate 

 specimens. 



1 39. Li ASTHENIA, Cass. (Aaa-devM, 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. ohtusifolia 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, Pospp. & Endl. Nov. Gen. & Spec. i. 15, t. 24, 26. 



Xj. 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 antliesis : leaves elongated- 

 linear : involucre about 1 5-toothed : corollas all shorter than the miimtely puberulent oblong- 

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

 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. HoLOGf MNE. 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. 

 Gojtt. 1837, 1839. Xantho, Eemy, in Ann. Sci. Nat. ser. 3, xii. 191. Lasthenia, 

 Lindl. Bot. Keg. 1. c. 



-^+-'-^ L. glabrata, Linbl. 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. glabmia 

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

 Lindl. Bot. Reg. t. 1780, 1823. Holoi/ijmne glabrata, Bartl. 1. c. ^fonoJopia glabrata, Fisch. 

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



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



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

 338), Breioer, Cleveland, Pringle. 



140. BURRIELIA, DC, partly. (Andres Marcos Burr lei, a Spanish 

 Jesuit and historian, who, in 17.')8, wrote a History of California, and edited the 

 account by Venega.s 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. mioroglossa, DC. 1. c. Slender annual, a span high, hirsute: leaves an inch long and 

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

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

 iJonglas.
