27. POITEA Vent. Choix pi. 36. 1807. 



Vilmorina DC. Prodr. 2: 239. 1825. 



Shrubs, with distichous odd-pinnate leaves, without stipels, the stipules subulate from a 

 broader base, united with each other inside the petioles. Flowers in axillary racemes, with 

 small bracts and no bractlets. Calyx cylindro-turbinate, acute at the base, more or less 

 distinctly articulate, 5-lobed, the teeth short and the upper two close together. Corolla 

 reddish-purple co white. Banner obovate, usually retuse, narrowed at the base, but scarcely 

 clawed, enclosing the bases of the other petals, not reflexed. Wings narrow, straight, linear 

 or linear-oblanceolate. Keel-petals narrow, straight, longer than the banner, oblanceolate, 

 obtuse, only slightly united, but with free tips. Stamens diadelphous, often exserted, the 

 sheath long and dilated above. Ovary stipitate, many-ovuled; style straight or slightly 

 curved upward, glabrous; stigma minute, terminal. Pod flat, linear, stipitate, 2-valved. 

 Seeds compressed, orbicular or obovate.
