TRIBE II.-GEN1STEJB. 



Shrubs or herbs. Leaves simple or digitately compound;

4. LUPINUS. 



A large genus of very ornamental annual or perennial 

 plants, rarely frutescent. Leaves 5- to many-foli&late, rarely 

 trifoliolate ; stipules adnate to the base of the long petiole. 

 Flowers variable in colour, blue lilac yellow or white, in terminal 

 racemes. Calyx 2-lipped. Wing petals connate at the tips ; 

 keel terminating in a curved beak. Pod flat, coriaceous or 

 fleshy. Upwards of eighty species have been described, chiefly 

 from temperate North America, a few tropical, and a few species 

 from the Mediterranean region. From lupus, a wolf or destroyer, 

 though the application is not clear. Very few of the species 

 are in general cultivation, but a great many handsome varieties 

 have resulted from intercrossing. 



Perennial Species. 



1. L. polyphyllus (fig. 66). Herbaceous, about 5 or 6 feet 

 high, leaflets very numerous, with immense racemes of usually 

 dark blue flowers, though variable in this respect, and often 

 with a mixture of white. This is the commonest and at the 

 same time one of the best species in cultivation. Native of 

 North-western America. 



2. L. mutcibilis. A rather tender herbaceous species, from 

 the Andes of Bogota. A strong-growing plant about a yard 

 high. Leaflets 7 to 9, linear-lanceolate. Flowers very fragrant 

 like the Sweet Pea, variable and changeable in colour, when 

 first open nearly white, and at length with tinges of yellow and 

 purple.
