| Distribution: |
South-west of Western Australia in shrubland or heathland. |
| Common Name: |
No generally accepted common name. |
| Derivation of Name: |
Dryandra...after Jonas Dryander, a swedish botanist.
ferruginea... From Latin ferrugineus, rust coloured, referring to the colour of the hairs on the undersurface of the leaves. |
| Conservation Status: |
Not considered to be at risk in the wild at the species level although several subspecies are poorly known and listed as Priority Species under the WA Wildlife Conservation Act. |
General Description:
Dryandra is a large genus of 135 species in the Protea family. Their nearest relative is the genus Banksia but, unlike the banksias, Dryandra occurs naturally only in Western Australia (Banksia can be found in all states and one species one even extends its range to islands to Australia's north).

| Dryandra ferruginea subsp. pumila |
Dryandra ferruginea is a small, variable shrub ranging from completely prostrate to a rounded form 1-1.5 metres in height. Generally the leaves are narrow and long (up to 450 mm) with triangular lobes and having sharp points. The individual small flowers occur in inflorescences on the ends of short branches but they are often held within the plant and may be partly hidden by the foliage. Flower colour may be cream, yellow, orange or brown. The inflorescences are surrounded by brown bracts, giving a Protea-like appearance.
The variability in habit has led to seven subspecies being recognised. The following brief descriptions of the subspecies is based on ninformation in Florabase:
- ferruginea - Erect to sprawling, bushy, non-lignotuberous shrub, 0.4-0.8 m high. Flowers cream, yellow, brown. Flowering from August to October.
- chelomacarpa - Prostrate shrub, to 0.45 m high. Flowers yellow. Flowering from July to October.
- flavescens - Prostrate, possibly lignotuberous shrub, to 0.45 m high. Flowers cream, yellow. Flowering July/August.
- magna - Very pooly known and no details available.
- obliquiloba - Ascending, lignotuberous shrub, to 1 m high. Flowers yellow. Flowering September/October.
- pumila - Erect, non-lignotuberous shrub, 0.2-0.5 m high. Flowers yellow. Flowering from August to October.
- tutanningensis - Bushy, erect, non-lignotuberous shrub, 0.5-1.5 m high. Flowers yellow, orange. Flowering September/October.
D.falcata has been grown by enthusiasts for some years but is not widely cultivated. It can be expected to be difficult to maintain in humid temperate and tropical areas. Excellent drainage and a sunny location are preferred. It is reported to be slow growing.
Propagation from seed is relatively easy and cuttings may be successful but slow to strike.
| Transfer of Dryandra to Banksia |
A paper published in February 2007 (see below) has proposed that the genus Dryandra be subsumed into Banksia. The paper publishes new names in Banksia for all currently recognised Dryandra species. At this stage ASGAP is retaining Dryandra as a separate genus until it becomes clear whether the published change will be generally accepted by Australia herbaria.
