released, return to their former position. The keel is 
saccate at base, turns abruptly upward and ends in a 
slender beak. 
The stamens are monadelphous, a round opening in the 
tube at base above allowing access to the nectar. When 
the flower opens five oblong anthers have discharged 
their pollen and five rounded anthers are still indehiscent. 
In the bud the long anthers surpass the others. The five 
stamens with long anthers rise to the tip of the keel, 
shed their pollen, and then withdraw. The five stamens 
with round anthers then lengthen, their indehiscent an- 
thers serving to push the pollen up into the apex of the 
keel. Then they shed their own pollen where it will be 
easily carried out by the style-brush. 
The style bends abruptly upward, and has a fringe of 
hairs above and a circle of hairs about the tip. When 
the keel is depressed, the style pushes out a ribbon of 
pollen. If the keel be further depressed, the style itself 
appears carrying out more pollen upon its brush. Ja. 21-
