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

7. LYCIUM, Linn. 

 Calyx 4-5-toothed or more deeply clelX, persistent ut the haso of the herry. 

 Corolla varying from short-funnelform to tubidar, the 4 or 5 lobos commonly im- 

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

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

 2-celled, slightly stalked in the calyx : style liliform : stigma cajjitate. Berry many- 

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

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

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

 linear, nearly veinless. l^etlicels 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 wami-temperate and subtropical zones, one species, native 

 of the Levant, &c., conuiionly planted for ornament in the Atlantic Uniteti 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. I'AI.mdum, Miers, the laigest flowered of all, with corolla 

 nearly an incli long, L. Pai,mei;i, Gniy, from W. Sonora, Mexico, with long calyx-lobes, L. 

 I'AKViFLOKUM, Only, from S. Arizona, with corolla only one sixth of an inch long, and two little- 

 known species of Lower ralifornia, viz. L. iikkvii'KS, Benth., with 5-mcrous slender flowers and 

 ucicular sitincs, and L. Kiciiii, (iray, may licnMifler lie found within the State. But the follow- 

 ing are all that aie now known within or ncai- its borders. l'\ii' an account of the North Anieiican
