Daviesia incrassata Sm. subsp. reversifolia (F.Muell.) Crisp (1995: 1201)

108b. Daviesia incrassata Sm. subsp. reversifolia (F.Muell.) Crisp (1995: 1201) View in CoL . Daviesia reversifolia Mueller (1859: 145) , Bentham (1864: 83). Type : ‘ In monte ‘ Flat-top Hill’ juxta rivum Fitzgerald River. Mxw.’ Holotype: MEL 80382 View Materials ; isotypes: K,? MEL 80383 View Materials

Branchlets terete, strongly flexuose. Phyllodes reflexed or spreading at 90°, terete, mostly 5–15 mm long in the adult plant. Juvenile phyllodes not retrorse, gently incurved, vertically compressed but not lobed, up to 8 cm long. ( Fig. 110A–C View FIGURE 110 ).

Flowering period:— July to November. Fruiting period: October and November.

Distribution:— This subspecies extends along the south coast and adjacent hinterland of Western Australia from Bremer Bay to Esperance. A specimen from Kangaroo Island, South Australia ( Tate s.n., AD 968010180) definitely belongs to this taxon. However, the locality requires verification, given the lack of precise locality details and a large disjunction from the nearest occurrence in WA.

Habitat:— Grows in sand or rocky soil in mallee-heath or kwongan heath.

Affinity:— This subspecies is easily distinguished from the others by its very tangled, intricate habit, zigzag branchlets and patent to strongly reflexed phyllodes. Around the distributional limits of subsp. reversifolia , occasional intermediates with subsp. incrassata are found, e.g. Crisp 5095 ( Fig. 110D, E View FIGURE 110 ).
