    Description - Stems up to about 1.5 m. high, hispidulous, sometimes glabrate; stipules 10-15 mm. long, 2-3 mm. wide, the apical portion acuminate, slightly more than twice as long as the acute to obtuse, sometimes erose, basal auricle, the margin closely denticulate-ciliate ; leaves 4-6 cm. long, about 25-40-foliolate, the petiole and rachis hispidulous; leaflets 5-10 mm. long, 1.5-3 mm. wide, denticulate-ciliate, the lower surface somewhat glaucous; pedicels and peduncles hispidulous; bracts graduating from stipule-like to subcordate-ovate, about 3-4 mm. long and 2 mm. wide, acute, serrulate, sometimes laciniate, ciliate; bracteoles lanceolate-ovate, acute to obtuse, denticulate-ciliate, about 2-4 mm. long, 1-2 mm. wide; flowers 10-12 mm. long; calyx 7-8 mm. long; standard 10-12 mm. long, the claw 0.5-1 mm. long, the blade ovate-suborbiculate, about 9.5-11 mm. long, 7-10 mm. wide, ciliate; wings about 9-11 mm. long, the claw 1 mm. long, the blade 8-10 mm. long, 3.5-4 mm. wide, ciliate in part; keel about 10-11 mm. long, the claws about 1 mm. long, the blades 9-10 mm. long, 3-3.5 mm. wide; stamens 10-12 mm. long; fruit 10-14-articulate, the margins subentire, the stipe about 7-11 mm. long, the articles 3-4 mm. long, about 4 mm. wide, hispidulous, often verrucose or muricate at the center; seeds about 3 mm. long and 2 mm. wide.

  • Discussion

    This species somewhat resembles Ae. evenia and Ae. pluriarticulata in fruit characters, but the fruits are longer stipitate and slightly more glandular. The denticulate leaflets are larger, but otherwise resemble those of Ae. evenia var. serrulata. The flowers of Ae. denticulata are considerably larger than those of Ae. evenia and Ae. scabra.
