SOUTH AMERICAN PLANTS. 137 



dulam dilatatam crassam margine dense barbatam geniculatis, 

 3 limbo sequilongis^ 2 pauUo brevioribus ; bacca oblonga, calyce 

 suffulta. — Frayle Muerto, Prov, Buenos Ayres. — 1\ v. 



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 j they are from 4 lines to 1| 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 arc large and generally alternate : the 

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

 is 2 lines long ; the tube of the corolla is 2 lines, the lobes of its 

 border 3 lines long ; the tube is encircled in its constricted part 

 by a narrow densely pilose ring, and is bearded internally be- 

 tween the insertion of the stamens; the filaments are thick, 

 fleshy, and geniculated at their origin below the fleshy glands, 

 which form a fornix closing the mouth of the corolla : the berry 

 is crimson^ oval, supported by the cup-shaped calyx with its teeth 

 reflexed ; it is 3 lines long and 2 lines broad*.

This is a very distincTspecies, much resembling L. fi 

 in all probability is referable to the same section : the branchlets 

 are very flexuose and thick ; the strong axillary spines, which are 

 about I an inch apart, and 1 or 1^ inch long, bear fascicles of 

 leaves at intervals of every 2 or 3 lines ; the leaves are 4 to 7 

 lines long and 1 line broad; the peduncle is 2 lines long, the 

 calyx about 1^ line in length; the dark-coloured berry 3 lines 

 long and 2 lines in diameter : flowers are wanting in the only 

 snecimen I have seent.
