The banner runs forward for 5 mm., its claw, as well 
as the claws of the other petals, being held by the calyx 
tube. To reach the nectar a tongue 4 or 5 mm. long is 
needed. The banner then bends upward, being con- 
cave in front and strongly reflexed on the sides. As it 
appears in front, it measures 7 mm. high and 4 mm. wide. 
The folds render it quite rigid, so that it resists upward 
pressure. 
The wings are free, lying close to the keel, their tips 
being bent to the right. This requires the bee to land 
on the right side and, as in 7. obcordatum, pollen contact 
is limited mainly to the left cheek. This slight disposi- 
tion of the wings makes the flower pleurotribe. A 
process in each wing fits in a pit in the keel, requiring 
the parts to move together. On the base of each wing is 
a hook-like process which clasps the stamen tube and pre- 
vents the wings and keel from being thrust aside. 
The keel petals are united. When the keel is de- 
pressed, all of the stamens are exposed. When freed, 
the keel again covers them. 
The stigma receives pollen from the bee before the 
anthers touch it. Self-pollination is hardly probable. 
Access to the nectar is on each side of the free stamen.

Trum Oscorpatum, Ma., R.—It grows flat on the 
ground, and bears short racemes of pale-bluish flowers, 
the tip of the keel being of a darker blue. The flower is 
10 mm. long, the banner 5 mm. wide. The banner runs 
forward for 6 mm., when it turns obliquely upward. At 
base the banner clasps the other petals and is itself
