half a_cylinder, and it incloses the parts which lie 
under it. The border is deptessed on each side, but 
the sides next to the edge are turned upwards, where 
the half cylinder terminates. At the commencement 
of the border there are 2 concave impressions, promi- 
nent on the under side, and compressing the wings 
which lie beneath them. The : 
Wings are 2 equal petals ; 1 placed on each side of 
the flower‘under the standard. The borders incum- 
bent, parallel, rounded, and oblong, broadest outwards, 
the upper edge pretty straight, the lower extended and 
rounded. e base of each wing is cloven, the lower 
segment si ae a claw, fixed to the side of the 
receptacle, and about as long as the cup; the upper 
segment shorter, and bent inwards, e 
Keel is the lowermost petal, generally deeply divided, 
placed under the standard, and between the wings. It 
13 boat-shaped, concave, compressed at the sides, placed 
-in' the position of a boat upon the water. It is muti- 
ated at the base, the lower part extending into a claw 
as long as the cup, and fixed to the receptacle. The 
upper and lateral segments shorter, and enfolded with 
those parts of the wings which resemble them in 
shape. The sides of the keel are shaped like the wings, 
and have a similar situation, only lower and more in- 
- ward. The line that forms the keel, in this eal is 
y 
straight as far as the middle, and then gradually rises 
in an arch ; but the marginal line runs straight to the 
extremity, until it meets with, and is lost in that of 
the keel.
