3. Brogniartieae. Erect shrubs. Pedicels paired in the axils or arranged 



in terminal racemes. Seeds with caruncle. Radicle of embryo 

 straight. Harpalyce, Brogniartia. 



4. Tephrosieae. Habit various. Inflorescences variable. Legume two- 



valved. Galega, Tephrosta, Millettia. 



5. Rohinieae. Habit various. Inflorescences axillary racemes or fasciculate 



at the older nodes. Posterior stamen often free. Legume two- 

 valved, usually flat. Robinia, Biserrula, Carmichaelia.

7. Astragaleae. Shrubs or herbs. Inflorescences all axillary. Flowers 



racemose or solitary. Standard petal erect, usually narrow. 

 Posterior stamen free. Style without beard. Legume usually 

 inflated, longitudinally septate. Astragalus, Oxytropis, Glycyr- 

 rhiza. 



VII. Hedysaroideae 



The stamens are ten in number and usually diadelphous. They are 

 characterized by the fruit, which is a lomentum and not a legume. 



1. Coronilleae. Shrubs or herbs. Leaves pinnate, rarely simple. 



Inflorescenes axillary, umbellate. Posterior stamen free. Stamen 

 filaments dilated upwards. Ortu'thopus, Coromlla, Hippocrepis. 



2. Euhedysareae. Herbs or sub-shrubs. Leaves pinnate, rarely with 



one leaflet. Stipules often dry and membranous. Inflorescences 

 axillary, racemose. Petals often withering but persistent. Wing 

 petal very short. Carina obliquely truncate at apex. Posterior 

 stamen usually free. Filaments not dilated. Hedysarum, 

 Onobrychis. 



3. Aeschynomeneae. Shrubs or herbs. Leaves pinnate, pinnae usually 



indefinite. Flowers in axillary racemes of few flowers. Alae 

 usually transversely folded. Stamens all united or united into 

 two groups. Posterior stamen rarely free. Aeschynomene, 

 Smithia. 



4. Adesmieae. Shrubs or herbs. Leaves pinnate, pinnae indefinite. 



Flowers in terminal racemes. Stamens all free. Patagonium,

5. Stylosantheae. Woody herbs, often gummy. Leaves with few 



pinnae. Flowers in capitate terminal spikes or axillary. Stamens 

 all united in a closed tube. Anthers alternately basifixed and 

 versatile. Stylosanthes, Arachis. 



6. Desmodieae. Herbs or woody climbers. Leaves pinnate, with three 



pinnae, terminal leaflet with two stipellae. Flowers usually in 

 pairs on rachis, racemes terminal or axillary. Standard petal 

 narrowed at the base, wing petals united to the keel near the
