This is an extremely polymorphous species, under which I 

 have united many forms which I formerly considered as distinct 

 species, but as there is little apparent difference in their floral 

 structure they must be regarded as mere varieties. They are all 

 widely spread over the extensive desert plains that skirt the 

 eastern side of the Andes ; many even reach the Atlantic ■ they 

 vary greatly m the shape and size of the leaves even in the' same 

 plant, m their more glabrous or pubescent habit, or in a greater 

 abundance or paucity of leaves and flowers. This species is 

 closely assimilated to L. salsum and L. Chilense, but still more 

 approaching L. Grevilkamm. In that variety which I have 

 taken as the type of the species, the whole plant is more pubes- 

 cent, the leaves linear, somewhat acute, 2 to 5 lines long, 4 to ^ 

 line broad, tapering into a short slender petiole : the peduncle is 

 f line long ; the tube of the pubescent calyx is l fine long its 

 pomted linear teeth 1 line in length ; the tube of the corolla is 

 pubescent externally, 1^ line long, the lobes of the border 2^ 

 hues long and 1^ line broad; the nearly equal stamens 3 lines 

 m length, attam the ends of the segments : the ovaiy and style 

 are 4^ Imes long. I found this plant on the Alto del Yeso a
