with many prominent ribs. Pedicels 0.5–1.5 mm long. Calyx including receptacle ca. 2.5 mm long. Corolla : standard ca. 5.5 × 5.5–6 mm including the 1.5 mm claw; wings 4 × 2.25 mm including the 1.5 mm claw; keel 3.5 × 1.5 mm including the 1 mm claw. ( Fig. 94 ).

Selected specimens (13 examined):— WESTERN AUSTRALIA. Roe: 20 km S of Lake King township and 8 km W of Lake King to Ravensthorpe road, 33°16’S, 119°41’E, P. G .

The flowers of subsp. redacta are generally larger (e.g. calyx ca. 3–3.5 mm long, standard ca. 6.5 mm broad).
