Solitary golden pea flowers with blackish back and reddish purple keel on erect long stalks.
Pod flattened, 1.5 cm long.  Flowering spring and summer. 
Propagation from scarified seed or cuttings.
May reach 20 cm high but is a neat, reasonably open ground cover for a well-drained, sunny site.
Frost hardy.

Muehlenbeckia axillaris
A prostrate, wiry plant, rooting at the nodes.  Insignificant greenish flowers and 5mm rounded leaves. A useful screening plant and adaptable and is found in naturally "benign" habitats or very cold, frosty and damp places. Prefers heavy soils.
Tas, NSW, Vic, ACT and New Zealand.



CLEMATIS ARISTATA                            Ranunculaceae                                                        Clematis
                                             
(Male Flowers)
Clematis aristata
Woody climber scrambling to 15m or higher over shrubs and trees. Leaves opposite,simple or compound, with 3 large leaflets to 9cm long, 5cm wide, stalks of leaves and leaflets often acting as tendrils.  Flowers about 4.5cm, creamy white, starry, with 4-7 long narrow segments.   Male and female flowers on separate plants. Male flowers more showy, with numerous pointed stamens; female flowers with many carpels with leathery styles persisting in the fruit. 
Flowering September-January.
Widespread, especially in lower montane forests and gullies, sometimes in drier light forest. Easily germinated from seed.

One other Tasmanian species is a climbing plant, C. microphylla, which is restricted to sand dunes near the north coast. This has leaves divided into three parts which are themselves divided into three leaflets.  The non-climbing C. gentianoides has similar flowers and is restricted to dry sites near Hobart and Launceston and near the east coast.  The introduced old man's beard, C.vitalba, is common in settled areas of the State.
