136 Ml'. J. Miers on the genus Lycium. 



costate nervures descend to the base ; the teeth^ more especially, 

 are covered with whitish pubescence. The corolla is cylindrical, 

 slightly swollen below the mouth; the tube is 6 lines long, i^ 

 line diameter in the broader part, and quite smooth ; the lobes of 

 the border are erect, orbicular, very small, ^th the length of the 

 tube, and are fimbriated on the margin with numerous ciliated 

 white hairs : the stamens are enclosed ; two of them nearly reach 

 the mouth of the tube, the other three being little more than 

 half their length ; all are pilose for a short portion of their length, 

 above the point of their insertion in the middle of the tube : the 

 style is slender below, much thickened above the middle, slightly 

 curved, and the length of the longer stamens : the stigma is 

 clavate and sub-bilobed : the ovary is narrow, oblong, smooth, 

 somewhat shorter than the calyx, and is invested at its base by 

 the very short induvial cup of the corolla : Schlechtendal states 

 that the berries are globose, red_, and 3 lines in diameter. 



29. Lycium elongatum (n. sp.) ; — glaberrimum, ramosum, ramu- 

 lis elongatis, spinescentibus, nodoso-flexuosis, glauco-griseis ; 

 fohis 4-8, fasciculatis, lineari-subulatis, obtusiusculis, imo in 

 petiolum gracilem longe attenuatis, carnosulis; floribus in 

 fasciculis solitariis, pedunculo folio dimidio breviori, calyce 

 brevi, tubuloso, 5-costato, acutissime 5-partito, corolla longe 

 et anguste tubulosa, glabra, sicca rubescente, imo coarctata, 

 superne vix infundibuliformi, limbi laciniis 5 breviter ovatis, 

 staminibus brevissimis, inclusis, ultra medium insertis, glabris, 

 in nervis totidem hirsutulis tubi decurrentibus, 3 longioribus 

 faucem vix attingentibus, 2 alteris istis dimidio brevioribus ; 

 stylo corollse tubo sequilongo. — Prov. Argentinas. — v. s. in 

 herb. Hook.; in desertis salsuginosis intra Cordovam et Santiago 

 de Tucuman [Tweedie, n. 1212). 



This plant, although very different in its growth, has its flowers 

 very similar to those of the preceding species. Tweedie remarks 

 that this and similar species, all low-growing shrubs, abound here 

 and in Patagonia in endless varieties ; (by Patagonia he means 

 the southern portion of the province of Buenos Ayres.) The 

 leaves, including the petiole of one-half their length, are 4 to 6 

 lines long and ^ line broad : the slender peduncle is 1^ line long : 

 the narrow, glabrous, tubular calyx, marked with deep red lines, 

 is ] ^ line long, and is half cleft into five acute linear teeth, having 

 pubescent margins : the tube of the corolla is 4 lines long, its 

 ovate lobes are barely | line long, the three longer stamens are 

 1 line, the two shorter ones ^ line in length*.
