beneath, coriaceous, dark-green above, brownish beneath, reticulate; flowers in fascicles on

 tube 2.5 mm. long, 2 mm. wide, the lobes lanceolate, 2 mm. long; corolla purple; banner 

 orbicular, spreading, 8 mm. long; blades of the wings oblong, with a rounded basal auricle; 

 keel-petals lunate, free at the tip, obtuse or acutish, 1 cm. long; style as in the preceding

16. NOTODON Urban, Symb. Ant. 1: 324. 1899. 



Shrubs, with or without infra-petiolar curved prickles. Leaves abruptly pinnate; stipules 

 lanceolate, with a subulate stiff apex, deciduous; petiole and rachis more or less winged, the 

 wings discontinuous at the insertion of the leaflets, the rachis produced into a short point; 

 leaflets entire, coriaceous, veinless; stipels minute. Flowers in small fascicles in the axils of 

 old leaves, appearing before the new ones. Calyx short-campanulate, remotely and minutely 

 5-lobed, the upper two lobes close together. Banner suborbicular, reflexed, with a very short 

 claw. Wings oblong, straight, with a curved claw. Keel-petals united by their upper half, 

 lunate, with the base truncate on one side, obtuse, much longer than the banner and less so 

 than the wings. Stamens diadelphous, the upper filament free, the rest united into a linear 

 sheath, nearly equal in length. Ovary short-stipitate, linear, several-ovuled. Style arcuate, 

 glabrous. Stigma minute, terminal. Pod linear-oblanceolate, acute at both ends.
