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

 M. balliaefolia, Benth. Smaller than the foregoing, and with similar flocculeut tomen- 

 tuni ; tlie .-<iini)le mouocephalous stems only 2 inches liigli : leaves small (at most half-inch 

 long), spatulate to lineai-, entire, or lower ones 3-lobed : head hardly 3 liue.s high : involucral 

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

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

139. LiASTH£1NIA, Cass. (Aao-Oevia, 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 liomogamous 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. Pliyt. iii. 88"; DC. in Lindl. Bot. Keg., 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, Pa;pp. & Endl. Kov. Gen. «& Spec. i. 15, t. 24, 25. 



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

 on long jteduncles wliich are enlarged at summit, nodding after antliesis : leaves elongated- 

 linear : involucre about 15-tootlied : corollas all sliorter than the minutely puberuleut oblong- 

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

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

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



§ 2. IIoLOOiMNE. 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. I'Jl. 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 liemispherical : 

 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. Beg. t. 1780, 1823. Iloloijijmne glahruin, Bartl. 1. c. Monolopia glah-ata, Fisch. 

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



Var. Coulteri. A smaller form : akenes smaller and narrower, w^ith obtuse edges, 

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

140. BURRIELIA, 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 somewliat 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, ecjualling tlie yellow flowers. — Low ground, 

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