THE DICOTYLEDONES 1667 



large size the classification of the Papilionaceae is necessarily somewhat 

 complicated. The following therefore is an outline of the main points. 



I. Sophoroideae 



The flowers have ten stamens which are all free, the leaves are compound 

 and are pinnately arranged. Sophora, Myroxylon. 



II. Podalyrioideae 



The flowers have ten stamens all of which are free. The leaves however 

 are either simple or palmate. Podalyria, Anagyris, Baptisia. 



III. Genistoideae 



The stamens are ten in number and generally monadelphous. The 

 plants are usually shrubs or occasionally herbs with simple or pinnate 

 compound leaves and entire leaflets. 



1. Liparieae. Leaves simple exstipulate, posterior stamen free, or 



rarely (in uniovulate genera) connate with the others. Seeds 

 with a caruncle (p. 1670). Priestleya, Liparia. 



2. Bossiaeae. Leaves simple, often stipulate. Stamens united into 



a tube which is split above. Seeds with a caruncle. Bossiaea, 

 Hovea. 



3. Crotalarieae. All stamens united into a tube which is split above. 



Seeds without a caruncle. Ciotalaiia, Lotononis, Aspalanthiis. 



4. Spartieae. All stamens united into a closed tube. Seeds without 



a caruncle. Lupimis, Spartium, Genista, Laburnum. 



5. Cytisieae. All stamens united into a closed tube. Seeds with a 



caruncle. Ulex, Cytisiis, Hypocalyptiis. 



IV. Trifolioideae 



The stamens are ten in number and either diadelphous or more rarely 

 monadelphous. The plants are herbs or rarely shrubs, with pinnately or 

 occasionally palmately trifoliate leaves, the veins generally ending in teeth 

 at the leaf margin. Ononis, Trigonella, Medicago, Melilotus, Trifolium. 



V. Lotoideae 



The stamens are ten in number and either diadelphous or monadelphous. 

 The plants are herbs or undershrubs with pinnately trifoliate or multifoliate 

 leaves with entire leaflets. Lotus, AnthyUis, Hosackia. 



VI. Galegoideae 



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

 are herbs, erect shrubs or, more rarely, trees or climbing shrubs with 

 pinnate leaves, and generally entire leaflets. 



1. Psoralieae. Shrubs or herbs with leaves glandular-punctate. 



Inflorescences racemes or spikes, terminal or axillary. Legume 

 small, indehiscent, usually one-seeded. Amorpha, Dalea. 



2. Indigofereae. Shrubs or herbs, often hairy. Inflorescences axillary 



racemes or spikes. Anther connectives with apical appendages. 

 Legume two-valved. Cyanopsis, Indigofera.
