232 SOLANACE^. Oryctes. 



eels solitary or sometimes 2 or 3 together, soon deflexed : calyx hirsute (a line and a half 

 becoming in fruit 2 or 3 lines long), divided to the base ; the divisions lanceolate : corolla 

 oblong and hardly longer than the calyx, naked within : dry berry globose, 4 lines in 

 diameter : seeds flat, rugose, oval, with excised hilum. — Arizona on the Sonoita, Wright 

 (no. 1692), with mature fruit and some undeveloped flower-buds; from the habit, calyx, 

 seeds, and high insertion of the stamens referred to the present genus. 



5. OIl"^CTES, S. Watson. {'Oyvxri^g, a digger, name given to this dubious 

 plant because it groves in the country of the Digger Indians.) — A single species, 

 known only from incomplete materials. 



O. Nevadensis, 'Watson. A low and insignificant winter-annual, 2 to 4 inches high, 

 when young somewhat scurfy or pruinose-pubescent, rather viscid : leaves oblong-ovate or 

 lanceolate, undulate, tapering at base into a petiole : pedicels 3 or 4 in a lateral fascicle, 

 shorter than the flower : calyx-lobes lanceolate, obtuse, rather shorter than the corolla, 

 about the length of the globose berry, loose : corolla 3 lines long, narrow, apparently 

 cylindraceous, blue or purplish ; the sinuses deeply induplicate in the bud : filaments 

 somewhat hairy, inclined to be unequal in length ; the longer ones and the filiform style 

 nearly equalling the corolla : seeds orbicular, flattened, f oveolate-reticulated. — Bot. King, 

 274, t. 28, fig. 9, 10 ; Benth. & Hook. Gen. ii. 893 ; Gray, Bot. Calif, i. 542. — W Nevada, 

 at the eastern base of the Virginia mountains, near the Big Bend of the Truckee, under 

 Artemisia bushes, in spring, WMson. ^ 



6. CHAKL^SAIIACHA, Gray. {Saracha is a tropical American genus, 

 dedicated by Ruiz & Pavon to Isidore Saracha, a Spanish Benedictine : the prefix 

 ^ufiai, on the ground, makes the meaning low Saracha.) — Texano-Californian 

 depressed perennials ; with mostly narrow leaves, either entire or pinnatifid, and 

 tapering into margined petioles, filiform naked pedicels, and either white, ochroleu- 

 cous, or violet-tinged corolla ; the close-fitting calyx in fruit obscurely if at all 

 veiny. — Benth. & Hook. Gen. ii. 891. Saracha § Chameesaracha, Gray, Proc. 

 Am. Acad. x. 62. 



* Stems branching, diffuse or at length depressed-procumbent: fruiting calyx almost globose: 

 seeds thickish, riigosely favosa. 

 - C. Coronopus, Gray. Green, almost glabrous, or beset with some short and roughish 

 hairs, diffusely very much branched : leaves lanceolate or linear with cuneate-attenuate 

 base, varying from nearly entire to laciniate-pinnatifid : peduncles elongated : calyx more 

 or less hirsute (the hairs often 2-forked at tip). — Bot. Calif, i. 540. Solanum Coronopus, 

 Dunal in DC. Prodr. 1. c. 64. Withania ? Coronopus, Torr. Bot. Mex. Bound. 155. Saracha 

 (Chameesaracha) Coronopus, Gray, Proc. Am. Acad. x. 62. —Clayey soil, Texas to southern 

 parts of Colorado and west to Arizona. (Adjacent Mex.) Corolla (yellowish), berry 

 (nearly white), and fruiting calyx nearly as in the next species, with which some speci- 

 mens seem to connect. To this probably belongs Saracha acutifolia, Miers in Ann. & Mag. 

 Nat. Hist. 1849, & 111. S. Am. PI. ii. 19, described from an incomplete specimen in Coulter's 

 collection, from California, or probably Arizona. 

 C. sordida, Gray, 1. c. Much branched from the root or base, somewhat cinereous with 

 short viscid or glandular pubescence, which occasionally becomes furfuraceous, also more 

 or less villous with longer hairs : leaves from obovate-spatulate or cuneate-oblong to 

 oblanceolate, and from repand to incisely pinnatifid (or even with the lobes sinuate-in- 

 cised) ; calyx when young viscid-villous. — Wilhanin? sordida, Dunal in DC. 1. i;. 450, 

 Torr. 1. c. Solanum coniodes, Moricand ex Dunal, 1. c. 64. S. Linsecumii, Buckley in Proc. 

 Acad. Philad. Saracha { Charnwsaracha) sordida, Gray, Proc. Am. Acad. 1. c. — Dry or 

 clayey soil, Texas and South-western Kansas to Arizona. (Adjacent Mex.) Corolla 

 dull pale yellow or sometimes violot-purple, about half inch in diameter. Berry the size 

 of a pea, all but the summit closely invested by tlie herbaceous calyx. Dunal's two 

 plants are the same, both being rather hoary and less hairy forms of a very variable 

 species.
