sweet flavour. The root yields a dark brown dye. The height 

 varies from 6 inches to 3 feet. Local name Urasu, or liquorice 

 plant."— W. Andrews. This plant seems to extend through a 

 jarge part of temperate South America. It is nowhere common, 



but is less rare on the eastern than on the western side of the 

 Andes.

 A small Vetch with blossoms of a deep brilliant blue with 

 white at the throat. Found in valleys, soil clay and moist. 

 Very widely distributed and abundant in mountain-ranges of 

 Central Patagonia."— W. Andrews. The vetches of South America 

 are very puzzling to the botanist. A considerable number of 

 closely allied forms extend through the continent from the 

 equator to the Straits of Magellan, if not also to Central America 

 and Mexico. The typical form of V. graminea is, I believe, con- 

 foed to the east side of the Andean chain, but closely allied 

 varieties or subspecies are found in Chili. 



103. Lathibus tomentosus, Lam. "Large blue blossom, 

 amongst sand-hills near coast."— IT. Andrews. This appears to 

 be a characteristic species of the east side of the continent, 

 extending from Port Desire (Puerto Deseado) in Patagonia 

 northward to Uruguay. Specimens labelled " Brasilia," collected 

 b y Sellow, were probably collected in Uruguay.

 Bolivia and Peru, and from Patagonia to Catamarca.
