4, LUPINUS. 
A large genus of very ornamental annual or perennial 
plants, rarely frutescent. Leaves 5- to many-folielate, 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, anda 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. polyphgllus (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. mutdbilis.—A rather tender herbaceous species, from 
the Andes of Bogota. A strong-growing plant about a yard 
high. Leaflets 7 to 9, linear-lanceolate. lowers very fragrant 
like the Sweet Pea, variable and changeable in colour, when
