Hakea collina is a shrub in the Proteaceae native to eastern Australia. A small many branched shrub with gnarled branches with attractive cream-yellowish flowers.
Hakea collina is an intricately branched often gnarled shrub growing to 1to high. Smaller branches and leaves have fine flattened silky hairs that remain until flowering. Straight needle-like leaves are crowded at the branch ends 1.5to long and 1.2to wide, sometimes grooved on the lower side. The inflorescence has two to twelve flowers with a white perianth 2.7to long and the style is about 9sigfig=1NaNsigfig=1 long. The pedicel is NaNsigfig=1NaNsigfig=1 long and covered with soft white hairs extending onto the lower part of the flower. The egg-shaped fruit are finely wrinkled, narrower at the stem 14to long and 6.5to wide. Fruit taper to a short pointed tip NaNsigfig=1NaNsigfig=1 long with no beak. The seeds are 11to long with a wing that is on one side. Flowers in the colder months from May to July.[1]
Hakea collina was first formally described by the botanist Cyril Tenison White in 1944 as part of the work Contributions to the Queensland Flora as published in the Proceedings of the Royal Society of Queensland.[2] The specific epithet (collina) is derived from the Latin word collinus meaning "of a hill" or "hilly",[3] referring to the habitat where the shrub occurs.[1]
It is endemic to an area in the south west of Queensland on lateritic tableland on hills and plains as a part of open Acacia woodland and shrubland communities.[4]
Hakea collina was classified as 'Poorly Known' in J.D.Briggs & J.H.Leigh, "Rare or Threatened Australian Plants" (1995).[1]
