Acacia flocktoniae

Flockton Wattle

Family: Fabaceae subfamily Mimosoideae

Acacia flocktoniae is a shrub growing to 3 metres high.

It has with a restricted distribution, found only in the Southern Blue Mountains (at Mt Victoria, Megalong Valley and Yerranderie, south to Picton) in New South Wales.

It grows on sandstone, in dry sclerophyll forest and woodland.

It is a listed threatened species in NSW.

Australian Wattles at least, can be broadly placed into 1 of 3 recognisable groups:

  • Group 1: Those that produce juvenile compound-bipinnate leaves and then change to producing adult-phyllodes which are modified-flattened petioles which form the foliage. This is combined with flowers produced in globular balls or heads (or ovoid heads). The heads can be singular in leaf/phyllode axils or arranged in groups.
  • Group 2: As for Group 1 but flowers are produced in longer rod-like spikes.
  • Group 3: Those that never produce phyllodes and retain the juvenile compound-bipinnate foliage into adulthood. These always produce flowers in globular balls (which are secondarily arranged into panicle or raceme-like groups in many cases).

This wattle belongs to Group 1.

The phyllodes are straight, to 10 cm long and to 0.5 cm wide.

Flowers are produced in globular heads, to 5 mm in diameter. Each head can have up to 30 very small, staminate flowers. Heads are produced on racemes in leaf axils with up to 10 heads per raceme, between August and September.

Pods straight to slightly curved or flat, to 11cm long, and only 0.7 mm wide.

In the garden

A rare plant in the wild. Cultivation potential is currently unknown. This is likely due to it being threatened with extinction. It may be more readily cultivated in the future.

Acacias can suffer from a number of pests, including borers, scale, galls and leaf miners. Growing plants suitable to your local environment minimises these occurring.

Propagation

Propagation is easy from scarified seed by covering with boiling water for 24 hours and discarding any seeds still floating on the surface.

Other information

Most wattles will die in a fire and regenerate from seed. Some species exhibit suckering from basal parts and roots.

Acacia is a highly diverse genus, with over 1500 recognised species (placing it in the top-10 most-diverse plant genera) occurring in most continents except for Europe. Australia has about 970 spp., most of which are endemic. There are also about 10 exotic species. NSW has about 235 recognised species. Some species have become weeds in other states outside of their natural range (e.g., wattles from Western Australia into NSW and vice versa).

Acacia – from Greek Akakia – which refers to an Ancient Greek preparation made from one of the many species; the name of which derives from akis, meaning “thorn” – referring to the thorns of species in Africa.

flocktoniae – named in honour of the botanical artist Margaret Flockton (1861-1953), who was the first botanical illustrator at the Royal Botanic Gardens in Sydney. There are some 1000 of her illustrations in The Botanic Gardens Trust Archive.

This plant is listed under both NSW and Commonwealth legislation as threatened with a category of vulnerable.
