S. DKiiii.r,, Wiilson, Mot. King Kxp. 102. Steins weak, 2 to 4 imlies liigli, lioni very slender 

 running rootstocks : ieuvcs rounded or ohovate, 1 to 3 lines long : Uowers on rather long nedii:els, 

 in small cynics, '6 lines long, yellow : jietiils lanceolate, acuniinato, twice longer than ihe acute 

 sepals ami little exceeding ihe stamens and styles. —In the mountains of Northern Nevada and 

 Utah {irulson, llaydcn), and probably ot Northeastern Calil'ornia ; Urst collected by Tulinie. 



+- -t- Leaves broadest at base, acute. 



5. S. Stenopetalum, Pursh. Stems erect or ascending from a branched pcr- 

 eunial ruotstock, 3 to (i inches high, simple or sometimes branclied : leaves narrowly 

 lanceolate, sessile, 2 to A lines long or more : flowers bright yellow, nearly sessile, 3 

 to 5 lines long : petals lanceolate, acuminate, twice longer than the acumiiiato se- 

 pals, and etiualling or exceeding the ytamens and elongated styles. — Torr. & (Jray, 

 Fl. i. 5G0; Watson, liot. King Exp. 101. 



Frequent from Oregon and Nevada to the Rocky Mountains, and doubtless to lie found in North- 

 eastern California. 



6. S. variegatum, Watson. Probably perennial with a subterranean rootstock, 

 dwarf, the slender simple stems only 2 inches high : leaves purplish, ovate-obh.ng, 

 2 lines long or less : Uowers 3 to G, in a contracted cyme, nearly sessile : petals 

 broadly lanceolate, acute, 2 lines long, yellow veined with purple, twice longer than 

 the, purple ovate ac\ite si'[)als ami a Httle exceeding the stamens and styli's. — Vvoc. 

 Am. Acad. xi. 137. 



Near San Diego, IJ. Cleveland, 1875. 



7. S. Douglasii, Hook. Branching at base, from a stout proliferous rootstock, 

 the rather stout stems 3 or 4 inches high : leaves lanceolate or the lowermost linear- 

 subulate, acute, membranaceous when dry, 3 to G lines long : (lowers somethues 

 polygamous, yellow, sessile, in an open cyme : petals 2 or 3 lines long, lanceolatts 

 acuminate, twice longer than the acuminate sepals and exceeding the stamens : ioUi- 

 cles at length divaricately sj)readiug from their united bases. — Fl. i. 228 ; Torr. S:, 

 (J ray, Fl. i. 5riD. 



Mendocino Co. (Jiulander) ; among limestone rocks on Gavilan Peak (Brewer) ; and northward 

 to Oregon. Remarkable for its divergent follicles. It is described as an annual, but may i.er- 

 haps be more jiersistent. 



8. S. pumilum, Benth. Annual, slender, branching or simple, 1 to 3 inches 

 high : leaves ovate-oblong, a line or two long : flowers sessile in sparingly branched 

 cymes, yellow : (;alyx-lobes very small, triangular, acute : petals linear, acute, 1^ lines 

 long, exceeding the stamens and styles : follicles short, 1-seedeil ; the seed enict, 

 filling the cavity. —PI. Hartw. 310. 



On gravelly soil in the Sacramento Valley (Hartwcg) ; at Placerville {Italian) ; Table Moun- 

 tain (Mrs. Ames) ; Oregon, Nuttall. It was also collected by Freviont. Peculiar \\\ its minute 

 calyx and solitary seeds. 



3. COTYLEDON, binn. 

 Calyx 5-parted. Petals united into a 5-lobed pitcher-shai)ed or cylindrical corolla. 

 Stamens 10, inserted on the corolla-tube. Carpels tlistinct, or rarely united at base, 

 many-seeded, beaked by the subulate styles. — Herbs, or soft-woody at base, ours 

 stout perennials ; leaves very thick and fleshy, entire, the lower rosulato ; flowers 

 often large and showy, mostly scarlet and yellow, in our species scorpioid-cymose 

 or in long racemes. — lienth. & Hook. Gen. PI. i. 659 ; Baker, Kefug. Bot. i. 

 (February, 18G9). Echeveriu, DC. Prodr. iii. 401. 



About 60 species, belonging to the dry or hot regions of the Old World and North America. 

 The Mexican species nuuiiier 2.5 or 30, and there is also another in New Mexico near the boundary.
