Description
Hakea trineura is a multi-stemmed shrub that grows from 1 to 3 m tall, re-sprouting from the base; the branchlets and young leaves are covered in a mat of soft brown hairs that become hairless with age. The leaves are on stalks 1 to 2.5 cm long. The leaf blades are 7 to 19.5 cm long and 1.3 to 7 cm wide, they are broadest at or above the middle, gradually narrowing to an obtuse to acute apex with a sharp point that is 1 to 2 mm long. The leaves have three longitudinal veins, with the secondary veins forming a conspicuous network between them. The inflorescences are 40 to 70 mm long, and have 60 to 80 flowers. The perianth is 7 to 8.5 mm long and is deep yellow in colour, and the style is green. The fruit is dry and woody, splitting open along one or both sides and is 2.3 to 3.5 cm long and 1.7 to 2 cm wide.
A closely related species from north-eastern NSW has previously been confused with H. trineura and is included under this name by some authors (e.g. Wrigley and Fagg, 1991). This NSW species is now known as H. archaeoides and is distinguished from H. trineura by its green rather than yellow perianth, red rather than green styles and shorter (1-2 cm) fruit (Barker, 1999).

Distribution
Hakea trineura occurs in the Marlborough and Rockhampton area of central eastern Queensland (Barker et al., 1999). Locations include Marlborough, Mount Slopeaway, Mount Redcliffe, Princhester, Ramilles Block, Glenavon, and Glen Geddes (Queensland Herbarium, 2012).

Range derived from extent of the taxon's verified records
Habitat
Hakea trineura occurs on serpentinite-derived soil, often in broad-leaved ironbark (Eucalyptus fibrosa) and Corymbia xanthope woodland over hummock grassland on hills (Barker et al., 1999). The species has not been located within protected or conservation areas (Queensland Herbarium, 2012).
Reproduction
Flowering occurs from May to September and plants resprout from the base (Barker et al., 1999).
Threatening processes
The main identified threats to Hakea trineura include loss of habitat from mining; loss and/or removal of individuals as a result of inappropriate fire regimes; and loss of habitat as a result of vegetation clearing (Batianoff et al., 2000; DERM, 2010).
Status notes
Hakea trineura is listed as Vulnerable under the Queensland Nature Conservation Act 1992 and Vulnerable under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999
Management recommendations
Management plans and strategies include: to liaise with research institutes to encourage research into fire regimes and the ecological and biological requirements of Hakea trineura (DERM, 2010).
Regional and local priority actions to support the recovery of Hakea trineura are outlined by DSEWPC (2012). A summary of these include: avoiding habitat loss, disturbance and modification (e.g. monitor known populations to identify key threats, minimise adverse impacts from agriculture at known sites; identify populations of high conservation priority); increasing conservation information (raise awareness of Hakea trineura in the local community); and enabling recovery of additional sites and/or populations (e.g. undertake appropriate seed collection and storage; investigate options for linking, enhancing or establishing additional populations).
Notes
Occurs in the following Queensland pastoral district: Port Curtis. Records of H. trineura in north-east NSW (Harden, 1991; Wrigley and Fagg, 1991) are now recognised as a distinct species H. archaeoides (Barker 1999).
