This species I found abundantly along the Desert track all the 

 way from Mendoza to San Luiz. It varies in having the leaves 

 more or less crowded^ more or less attenuated; they are from 3 

 to 6 lines long^ ^ line broad ; the peduncle is 1~ or 3 lines long ; 

 the calycine tube is cylindrical, | line long, with narrow, linear, 

 acute segments 1^ line long : the tube of the corolla is 4 or 5 

 lines long, the segments of its border are f line long, the larger 

 stamens are 2 lines in length : the oval berry is 3 lines long*.

This is evidently very near L, Berlandieri, and may possibly 

 be only a tetramerous variety of it. It appears to be more barren 

 of leaves, which are smaller and fewer in each fascicle : the leaves 

 are 2|-3 lines long, ^ line broad; the pedicels are 2-2| lines 

 long, the calyx is nearly a line long, the tube of the corolla 

 2 lines, the segment of the border If line in length; the con- 

 tracted portion of the tube is narrow, and a little longer than 

 the calyx, when it is suddenly enlarged into a bell-shaped form ; 

 the style is the length of the longer stamens, and the lower part 

 of the ovarium is encircled by the cupular remains of the corolla, 

 which here breaks away by a circumscissile line : this same pro- 

 cess is described as existing in L. Berlandieri ; but it partakes in 

 no de«:ree of the nature of a disk, as stated bv M. Dunalt.
