Keel, Stamens and Pistil
Fairy Hill, 35 km North of Regina on Highway #6
Note the keel has been manually pulled back from the stamens and pistil in this photo.
In most Saskatchewan legumes, nine of the ten stamens are united at least part-way by their filaments leaving the last stamen distinct. However, in this species all the stamens are distinct. Note the keel attaches to the receptacle by two thin, filament-like structures.
