Hakea trineura is a flowering plant in the family Proteaceae and is endemic to Queensland. The branches and leaves are covered with rusty hairs and the pendulous flowers are greenish-yellow.
Hakea trineura is a multi-stemmed shrub growing to NaNsigfig=1NaNsigfig=1 high and forms a lignotuber. The branchlets and new leaf growth have flattened, brown, short soft silky hairs, or are smooth. The leaves grow on a petiole about long. They are narrowly elliptic to egg-shaped NaNsigfig=1NaNsigfig=1 long by NaNsigfig=1NaNsigfig=1 wide with three distinct longitudinal veins. The leaves narrow gradually to the apex ending either with a sharp point or rounded. The inflorescence consists of 60-80 greenish-yellow flowers on a smooth or with sparsely flattened soft hairs on a rachis up to NaNsigfig=1NaNsigfig=1 long. The mid-green pedicel NaNsigfig=1NaNsigfig=1 long and smooth. The deep yellow perianths are NaNsigfig=1NaNsigfig=1 long and are smooth or with a few hairs when in bud. The styles are mid-green and the pistil long.Flowering occurs from May to September and the fruit are smooth, obliquely egg-shaped NaNsigfig=1NaNsigfig=1 long by NaNsigfig=1NaNsigfig=1 wide and slightly curved.[1] [2] [3]
Hakea trineura was first formally described in 1868 by Ferdinand von Mueller who gave it the name Grevillea trineura and published the description in Fragmenta Phytographiae Australiae.[4] [5] In 1868 Mueller changed the name to Hakea trineura.[6] It is said to be named from the Greek trineura referring to the three-veined leaves.[1] Trineura is however not attested in ancient Greek.[7]
Hakea trineura is restricted to the Maryborough to Rockhampton area of Queensland. It grows in hilly eucalyptus woodland over hummock grasslands. It is a quick growing shrub in tropical areas.[1] [2]
Hakea trineura is listed as "vulnerable" by the Australian Department of the Environment Protection and Biodiversity Conservation Act.[2]
