Mr. J. Miei's on the geims Lycium. 19 



19. Lycium tetrandrwn, Thunb. Linn. Trans, ix. 154-. tab. 15; 

 Dunal in DC. Prodr. xiii. 516. Lycium horridum, Thunb. 

 loc.cit. 152. tab. 17; Dunal, loc.cit. 516; — intricato-ramosis- 

 simuni, spinosum, ramulis patentibus, nodulosis, foliis e nodis 

 fasciculatis, obovativS, vel elliptico-oblongis, basi in petiolum 

 brevissimum attenuatis, crassiusculis, glabris ; floribus 4-meris 

 in fasciculis solitariis, pedunculo brevissimo, calyce poculi- 

 formi, glabro, 4-costato, 4-dentato, dentibus brevibus ciliatis, 

 corolla glabra, infundibuliformi, liinbi laciniis rotundatis, 

 margine ciliatis, tnbo 4to brevioribus; staminibus 2 longi- 

 oribus exsertis, 2 alternis faucem attingentibus, filamentis 

 longe supra medium insertis, hinc geniculatis, nudis, et cum 

 fasciculis totidem pilorum tubo adnatis alternis/ mox globula 

 pilorum donatis, superne glabris. — C.B. S — v. s. in herb. Hook. 

 [Drege, 7872). — Uitenhage [Harvey, no. 865). — Inherb. meo, 

 Uitenhage [Harvey, no. 1034, sub nomine Lycium horridum). 



Upon the same sheet in Sir Wm. Hooker^s herbarium I find 

 four specimens of Drege's collection, all fragments and very bare 

 of leaves ; two of these agree with the figure of Thunberg's 

 L. tetrandrum, the others, evidently younger branchlets, answer 

 to his L. horridum ; the structure of the flowers being exactly 

 alike in both. I cannot perceive, in the copious descriptions of 

 these two species by M. Dunal above quoted, anything that can 

 constitute valid differential characters; we may therefore con- 

 sider them as identical, as Sprengel long ago determined (Syst. 

 i. 700). The older leaves are fleshy, 3 lines long and ^ line 

 broad ; the younger leaves are obovate, 2 lines long : in Dr. Har- 

 vey's specimen the leaves are obovate, spathulate, 7 lines long, 

 2i lines broad; the peduncle is 1^ line, the calyx 1 line, the 

 tube of the corolla 3 lines, the segments of its border |^ or | line 

 long*.

 infra medium tubi insertis, 2 longioribus multo exsertis, 1 me- 

 diano faucem attingente, 2 brevioribus inclusis ; filamentis imo 

 glabris et geniculatis,. mox fasciculo globoso pilorum barbatis, 

 inde glabris. — C. B. S. — v. s. in herb. Hook. [Drege, sub nomine 

 L. tenue.)
