Family:

Fabaceae

Daviesia mimosoides

Slender Bitter-pea

Other Names: Leafy Bitter-pea, Bitter-pea

Name Origin:

Daviesia — after botanist the Rev. Hugh Davies (1739-1821).

mimosoides — mimosa-like, referring to similarity of ‘leaves’ to those of Acacia species.

Regional Subspecies:

D. m. subsp. mimosoides; D. m. subsp. acris (rare to east of Riv.)

Similar Species:

Narrow-leaf Bitter-pea has wider ‘leaves’ and flowers slightly earlier than Slender Bitter-pea (D. leptophylla).

Occurrence:

Regional:

Quite widespread in most catchments and districts. Less common in the drier areas to the west.

Australia:

Qld, NSW, Vic.

Habitat:

Sclerophyll communities, mostly on acidic soils, 0-1500 m altitude (often dominant understorey shrub).

Habit:

Multi-stemmed, open- branched erect shrub, 1-2 m high with narrow ‘leaves’ 2-20 cm long.

Site Preference:

Well-drained soils. Tolerates frost.

Flowering:

Yellow and red-brown, Sep-Nov.

Seed Collection:

Early Dec to late Jan. Monitor very closely as seeds released immediately or within 1-2 days of maturity. To ensure collection, cover fruiting branches with nylon stockings or paper bags after flowering. Ripe pods light-brown and brittle and rattle when shaken, with dark-coloured seed. May be difficult to obtain seed in useful quantities. Long storage life.

Propagation:

From scarified seed. Soak in near-boiling water for about 30 seconds, before cooling rapidly under flowing cold water. Alternatively soak in cold water for several hours. Dry to prevent rotting, before sowing. Germination takes 3-8 weeks. Suitable for direct seeding in pots (2-3 seeds per pot).

Regeneration:

From seed or suckers, particularly after fire.

VALUES:

Shade & Shelter:

Useful low-level cover in windbreaks.

Land Protection:

Useful understorey in recharge plantings. Legume — improves soil fertility through ‘fixing’ nitrogen.

Wildlife:

Good habitat. Flowers are a pollen and excellent nectar source for various native insects and birds.

Ornamental:

Very decorative. Interesting foliage and attractive perfumed flowers. Plant in clumps to form dense thickets for best effect. Pruning encourages dense growth.
