96a. Daviesia intricata Crisp subsp. intricata

Reference: Crisp (1995: 1205).

Plants large (to 2 m high) and hummocky, very intricate due to the divaricate branching. Branchlets slightly to strongly flexuose, sometimes arching. Phyllodes terete or some slightly vertically compressed. Corolla : standard ca. 5.5 × 6.5–7 mm including the 0.75–1 mm claw; wings ca. 4.5 × 2.2–2.5 mm including the 1 mm claw. Pod 9–10 × 7.5–8 mm. ( Fig. 97A–C ).

Flowering period:— June to August. Fruiting period: September and October.

Distribution:— Western Australia, from the Charles Gardner Reserve (near Tammin) south to Dumbleyung and south-east to Ravensthorpe.

Habitat:— On yellow or brownish, sometimes clayey, sand, occasionally with outcropping laterite, gravelly laterite and gravelly sandy loam, on undulating to flat terrain, in eucalypt woodland or mallee, low, shrubby heathland, or tall shrubland, with a large variety of understorey species.

Affinity:— Subsp. xiphophylla differs in having a smaller stature (generally 0.5 m high), non-intertwining branchlets, phyllodes that are vertically compressed and never terete, smaller flowers (e.g. standard 4.5–5 × 5 mm), and smaller pods (7–8 × 6–7 mm).
