Mr. J. Miers on the genus Lyciuin. 343 



I'esembles L. scoparium, and might almost be considered as a 

 variety of that species, which is equally abundant in drier places ; 

 it differs however in having the stamens and style much shorter. 

 The leaves are 5 lines to 1 inch long, 1 to 1| line broad : the pe- 

 duncle measures 3 lines ; the calyx, 2| lines long, is divided nearly 

 half-way into five narrow acute erect teeth ; the corolla much 

 resembles that of L. Chilense in form, size, and colour, and is 

 equally pubescent externally, the tube being 1 \ line, and the seg- 

 ments of the border 2 lines in length ; the tube a little above its 

 base is much constricted, fleshy, and clothed by a densely barbate 

 ring : the stamens are inserted a little above the constricted 

 portion of the tube, where they are geniculated and glabrous ; 

 above this they are each furnished with an adnate fimbriated 

 linear gland, forming together a fornix, that closes the mouth of 

 the corolla over the ovary; the berry is nearly 4 lines long and 

 3 lines broad*.

Specimens of this very distinct species exist also in Sir Wm. 

 Hooker's herbarium, collected by Tweedie in Buenos Ayres, 

 Uruguay, Entre Rios, Banda Oriental, and the banks of the river 

 Parana. It is readily distinguished by its rather large alternate 

 leaves covered with minute white spots, with its margins always 

 unevenly jagged; they are from 4 lines to If inch long, inclu- 

 ding the short petiole, and from 3 to 6 lines broad; they are 

 sometimes small and more ovate ; the older leaves are glabrous, 

 those in the younger axils are large and generally alternate : the 

 peduncle is 2^ or 3 lines long ; the calyx including its segments
