The pedicels are again twisted, so that the keel is turned 
upwards and the vexillum downwards. The calyx tube is 
5™" long, and its teeth extend 11™" beyond the tube. The 
vexillum is large and orbicular. The wings almost equal the 
keel in size, the latter being about one-half to four-sevenths 
the length of the standard. The wings are appressed to the 
sides of the keel, following its curvature, and are pasted to 
the latter by a mucilaginous substance. . The two petals of 
the keel are grown together along their (structuraily) lower, 
inner sides, and, excepting at the base, also along their up- 
per sides, which do not overlap, but meet along their edges. 
Perhaps the microscope might show that they were here held 
together along their thin edge by mucilage, but under an or- 
dinary lens they seem to have actually grown together, 
though so weakly as to permit of separation with any moder- 
ately pointed instrument. At the apex of the keel the petals 
owever remain free for a length of 4 or 5", and through this 
slit both the upper part of the style and the stamens are pro- 
truded when the flower is visited by bees. This being the 
case there is no need of hairs along the flattened style to serve 
as a pollen brush and these are absent. The stigma however 
is hairy, the largest hairs being along the upper margin.

the Sides are a little grown together or held together by peers 
mucilaginous substance. The terminal bud on the axis of the
