SPRINGTIME IN TASMANIA - PART 6




Yellow flowers on a plant with narrow linear leaves which are usually shiny. The reverse of the leaf is marked with two narrow indentations from the base to the apex. One of a large number of heathland shrubs which have narrow linear leaves about 1 cm long. In some dry areas the leaves have a grey appearance caused by dense minute hairs.
The yellow flowers have a group of up to 10 stamens clustered at the centre.
Flowering period - mostly late spring and early summer but also at other times. May be propagated from cuttings, but may form an untidy shrub if not pruned carefully.
Abundant in the eastern part of Tasmania.  Also in WA, SA, Vic, NSW, Qld.

Flowers:  Bright yellow, 5 deeply notched petals to 2cm  across, singly or in groups of 2-3 at the end of side branches and crowded among leaves at the end of the main stems. Stamens grouped to one side of the carpels.
Flowering: Spring.
Fruit: A follicle.
Habitat/Distribution:    Widespread and locally common in coastal heaths and in north and north-west.
Also SA, Vic, NSW, Qld.
