212 DROSERACE^. Cotyledon. 



4 inches long, very acute : floAvering brandies a span high or often less, with scat- 

 tered broadly ovate to lanceolate clasping leaves : inflorescence a rather close and 

 short compound cyme ; bracts ovate-lanceolate, rather large ; pedicels stout, 1 to 3 

 lines long : sepals broadly lanceolate, about 3 lines long : petals yellow, oblong- 

 lanceolate, mostly acuminate, 4 to 6 lines long : carpels ovate-oblong, about 3 lines 



•long. — Baker, 1. c, t. 71. Echeveria farinosa, Lindl. in Jour. Hort. Soc. iv. 292. 

 Mt. Carmel {Hartwcg) ; Paelieco's Peak {Brewer) ; Knight's Ferry, Bkjclow. It probably also 



.includes a more northern form with longer pedicels, collected on the upper tributaries of the 

 Sacramento {Fremont), at Sonoma {Bigcloiv), and also by Bridges. It seems to be a variable 

 species, distinguished from the last by its more lanceolate and narrowly acute less farinose leaves, 

 shorter flowering branches, longer sepals, and shorter carpels. A cultivated specimen at Cambridge 

 has very large liracts, much exceeding the pedicels. 



5. C. caespitosa, Haworth. Acaulescent or nearly so, glabrous : rosulate leaves 

 "glaucous-green," ovate-oblong to oblong-lanceolate, acute, the larger \\ to 3 inches 

 long; flowering branches 6 to 12 inches high, with broadly triangular- ovate clasp- 

 ing leaves : inflorescence a short and rather close compound cyme ; bracts broad and 

 rather large ; pedicels short and stout : sepals ovate, 2 lines long or less : petals 

 yellow, broadly lanceolate, acute, 4 or 5 lines long : carpels ovate-oblong, nearly 3 

 lines long. — Misc. Kat. 180; DC. Ear. PL Geiiev. 50, t. 14; Baker, 1. c, t. 69.

Near San Francisco and northward, first collected by Menzies and cultivated at the Kew Gar- 

 dens iu 1796 ; near Clear Lake {Torrcy) ; also from Gibbons and Pickering. 



6. C. laxa, Benth. & Hook. Xearly acaulescent, very glaucous : rosulate leaves 

 lanceolate, sharply acuminate, the larger 3 or 4 inches long or more : flowering 

 branches a foot or two high, slender, with scattered leaves, the lower usually nar- 

 rowly lanceolate, the upper shorter and broader : inflorescence of 2 to 4 simple 

 secund racemes 3 to 5 inches long ; floral bracts small ; pedicels 2 or 3 lines long : 

 sepals ovate, acute, 2 lines long or more : petals yellow, oblong-lanceolate, acute or 

 acuminate, 5 to 7 lines long : carpels ovate-oblong, 4 lines long. — Echeveria laxa, 

 Lindl. in Jour. Hort. Soc. iv. 292. Cotyledon Californica, Baker, 1. c, t. 70. 



Near Monterey {Hartwcg) ; Cajon Pass {Bigclow) ; on dry rocks in the Gavilan Range (Breicer) ; 

 Ft. Tejon {Xaritiis) ; rocky hills back of Santa Barbara, Bothrock. Some of the latter specimens 

 have reddish Jlowiis, and the mature carpels are linear-oblong. 



7. C. Nevadensis, Watson. Acaulescent, glaucous : rosulate leaves obovate to 

 oblanceolate, somewhat rhomboidal, acute or acuminate, the larger 2 to 4 inches 

 long : flowering branches 6 to 10 inches high, with scattered lanceolate to broadly 

 triangular acute leaves : inflorescence a rather close spreading compound cyme ; 

 bracts small ; pedicels 3 to 9 lines long : sej^als ovate, acute, 2 lines long or less : 

 petals lanceolate, acute, 5 lines long, yellow tinged with red : carpels very short, 

 ovate-oblong, 3 lines long in fruit. 



Hillsides and rocky places, Sonora {Bigclow) ; Yosemite Valley, Torrcy, Gray. 



Order XXXYI. DROSERACE^. 



Herbs, groAving in bogs, or rarely aquatic, most resembling Saxifragea; in habit 



and structure, and seemingly somewhat connected with that tribe through Parnassia, 



but with petals and stamens hypogynous or nearly so, anthers commonly extrorse, 



and the leaves provided with secreting glands of some kind, which appear to be in 



some way subservient to tlie capture of insects. 



A small order of five very small and local genera and one rather large and widely diffused one : 

 represented in N. America only by the wonderful Bionoia, or Veuus's Fly-trap, of Noith Caro- 

 lina, and by a few species of the principal genus, Drosern.
