Queensland Native Seeds

Acacia disparrima subsp. disparrima

Scientific NameAcacia disparrima subsp. disparrima
CategoriesNitrogen FixerTreeWattle
Common Name(s)Southern Salwood
FamilyFabaceae, Subfamily Mimosoideae

Description

Forms a tree to 12m high. Phyllodes to 14cm long with many, parallel, non-anastomosing nerves are an identifying feature. Produces yellow flower spikes to 7cm long.

Notes

"The subspecies is commonly associated with open forests, woodlands, the margins of sub-tropical, closed forest types and along disturbed roadsides. Flowers Jan.-May." (WorldWideWattle, Ver. 2)

Along the Queensland coast, Acacia disparrima subsp.disparrima blends in with other large Acacias. These may include Acacia maidenii, Acacia melanoxylon, Acacia concurrens, Acacia aulococarpa and even Acacia leiocalyx. Attention to presentation of nerves in phyllodes (when fruit not present), the physical appearance of pods and aril colour is necessary to begin seperating these taxa.

In subcoastal southern Queensland we often encounter Acacia disparrima subsp. disparrima around dry rainforest on undulating, lateritic country. On the coastal range it grows on metamorphics in eucalypt tall open forest besides more fertile basaltic soils and on the coastal plain its found on including deep sandy loams along beaches in very close proximity to salt water, even where tidal inundation affects the root zone.

The seed collector will find this species difficult to deal with in the cleaning process because it does not so readily let go of seed; pods tend to dehisce very little once collected. There is variation and room for method improvement. However, the species is certainly relevant to a large number of potential rehabilitation sites and is worth persisting with and promoting.

Historical Notes

Distribution

"Subspecies disparrima occurs predominantly in coastal and near-coastal areas with some extension into the adjoining tablelands, from Mackay in Qld S to Mylestrom (S of Coffs Harbour)in N.S.W. It is present on a number of continental islands in Qld between Rockhampton and Brisbane, e.g. Curtis, Hummocky, Facing, Fraser and South Stradbroke Islands." (WorldWideWattle, Ver. 2)
