PEA FAMILY. Fabaceae. 
There are so many western kinds of Lupinus that it is — 
hopeless for the amateur to distinguish them; herbs, 
sometimes shrubs; leaves palmately-compound, stipules 
adhering to the base of the leaf-stalk, leaflets, more than 
three in number, usually closing at mid-day; flowers showy, 
in terminal racemes; calyx deeply toothed, two-lipped; 
standard broad, the edges rolling back, wings lightly ad- 
hering above, enclosing the incurved, pointed keel, some- 
times beaked; style incurved, stigma bearded; stamens 
united by their filaments, alternate anthers shorter; pod 
two-valved, leathery, flat, oblong; seeds two to twelve. 
Lupines always have palmately-divided leaves, and are 
never trailing, twining, or tendril-bearing and thus may be 
superficially distinguished from Vetches and Peas, and 
from Thermopsis, by the united stamens. 
: A stately perennial, about three feet 
so high, with stout, branching reddish, 
Lupinus : : 
es slightly downy stems, bearing several tall 
Blue and white spires of flowers. The handsome leaves 
and purple are bright green, smooth on the upper 
Sears side, slightly downy, but not silvery, on 
Northwest : : 
the under, with from seven to thirteen 
leaflets, and the flower-cluster is very erect and compact, 
eight or ten inches long, beautifully shaded in color, from 
the pale, silky buds at the tip, to the blue and purple of 
the open flowers, which are about five-eighths of an inch 
long, with a lilac standard, tipped with purple. The upper 
flowers have white wings, veined with blue, and a green 
calyx, with reddish teeth, and the lower flowers have bright 
blue wings, veined with purple, and a reddish-purple calyx. 
This grows in wet places. 
Tree Lupiné A conspicuous shrub, four to eight feet 
Lupinus arboreus igh, with a thick trunk, gnarled and 
Yellow twisted below, with purplish, downy 
Spring branches, silvery twigs and dull bluish- 
Caltcats green leaves, downy on the under side, 
with about nine leaflets. The fine flower clusters are 
sometimes a foot long, composed of beautiful canary- 
yellow flowers, deliciously sweet-scented. This is easily 
recognized by its size and fragrance and is common in 
sandy soil near the sea, where it has been found very useful, 
as its very long roots keep the sand dunes from shifting.
