Phyllodes <10 mm long and up to 1.5 mm broad at base, often very small or apparently absent but can be felt as sharp spines. ( Fig. 91E, F ).

Distribution:— Western Australia, mainly inland of subsp. hakeoides , from Yuna south to Mount Barker and in the northern, central and southern wheatbelt.

Habitat:— Grows on drier sites than subsp. hakeoides , more commonly occurring in kwongan (heath) than in jarrah-marri forest.

Affinity:— Differs from subsp. hakeoides in having shorter phyllodes <10 mm long. Similar to D. debilior , D. gracilis and D. triflora , but all three of these species are quite leafless (running a finger down the branchlets of subsp. subnuda immediately reveals the presence of the pungent phyllodes), and D. triflora has a strictly 3- flowered inflorescence. Daviesia debilior susbp. sinuans is very similar to and overlaps in distribution with D. hakeoides subsp. subnuda but, in addition to the complete absence of phyllodes, may be distinguished by the pods, which have an evenly curved, obtuse lower suture (not indented near the apex) and by the calyx, in which the lower three lobes are neither flared outwards or incurved at the tips.
