542 SOLAN ACE^E. Oryctes. 



Stamens somewhat unequal in length : filaments slender, included : anthers very 

 short. Seeds, habit, &c., of Physalis and the related genera. A single species. 



1. O. Nevadensis, Watson. Annual herb, a span high, with some rather 

 scurfy viscid pubescence : leaves ovate, oblong, or lanceolate, with undulate margins, 

 the base tapering into a petiole : pedicels 2 to 4 in an axillary sessile umbel : corolla 

 blue or purplish, 3 lines long. Bot. King Exp. 274, t. 18, tig. 5-10. 



Eastern foot-hills of the Virginia Mountains, Nevada, in stony barren soil under Artemisia 

 bushes, near the Big Bend of the Truckee, Watson. Not again met with as yet. Mature fruit 

 is desired. Evidently the seed figured was immature and the embryo not fully grown. 



7. LYCIUM, Linn. 



Calyx 4-5-toothed or more deeply cleft, persistent at the base of the berry. 

 Corolla varying from short-funnelform to tubular, the 4 or 5 lobes commonly im- 

 bricated in the bud, the sinuses often plaited. Filaments filiform, included or 

 exserted : anthers short, fixed by the middle ; the cells opening lengthwise. Ovary 

 2-celled, slightly stalked in the calyx : style filiform : stigma capitate. Berry many- 

 seeded. Seeds roundish : embryo coiled or curved, slender. Shrubs, mostly 

 spiny, diffusely much branched ; with entire alternate leaves, commonly fascicled in 

 the axils or on short axillary spurs, in our species small and spatulate or somewhat 

 linear, nearly veinless. Pedicels solitary or fascicled, mostly from the leafy fas- 

 cicles. Flowers white or purplish. Berries small, usually red, sometimes white. 



A large genus, dispersed over the warm-temperate and subtropical zones, one species, native 

 of the Levant, &c., commonly planted for ornament in the Atlantic United States (under the 

 name of Matrimony Vine), but it is by no means showy ; several are indigenous to the Mexican 

 frontier and its vicinity. Of these L. PALLIDUM, Miers, the largest flowered of all, with corolla 

 nearly an inch long, L. PALMEIU, Gray, from W. Sonora, Mexico, with long calyx-lobes, L. 

 PARVIFLORUM, Gray, from S. Arizona, with corolla only one sixth of an inch long, and two little- 

 known species of Lower California, viz. L. BREVIPES, Benth., with 5-merous slender flowers and 

 acicular spines, and L. RICHII, Gray, may hereafter be found within the State. But the follow- 

 ing are all that are now known within or near its borders. For an account of the North American 

 species, see Proc. Am. Acad. vi. 45, vii. 388, & viii. 292. 



* Lobes of the calyx foliaceous, as long as the tube. 



1. L. Cooperi, Gray. Minutely pubescent, with stout branches and some very 

 short spines : leaves spatulate, apparently somewhat viscid, half an inch or more 

 long : pedicels about the length of the cylindraceous or when old campanulate 

 calyx, both somewhat hirsute ; lobes of the latter oblong and not longer than the 

 tube : corolla apparently white, narrow-funnelform, half an inch long, its ovate 

 lobes short : filaments hairy at base: anthers oval, mucronulate. Proc. Am. Acad. 

 vii. 388. 



San Bernardino Co., on the eastern slope of Providence Mountains, Cooper. 



2. L. macrodon, Gray. Puberulent, becoming glabrate : leaves spatulate -ob- 

 lauceolate, only 2 to 4 lines long : pedicels very short : calyx minutely viscid ; its 

 lobes narrowly linear and twice the length of the short campanulate tube, half 

 the length of the narrow corolla : filaments slightly hairy at base : anthers oval- 

 oblong. Proc. 1. c. vi. 46. 



California or Nevada, Fremont (coll. 1849 ; not otherwise known). 



* * Calyx with 4 or 5 short teeth, or sometimes irregularly 2 3-cleft. 

 +- Corolla very small and short. 



3. L. Calif ornicum, Nutt. in herb. Glabrous, very much branched, 2 to 4 

 feet high : branchlets spinescent : leaves thick and fleshy, very small, in the fascicles
