Hakea loranthifolia is an upright, open shrub typically growing to a height of 2 to 3 metres (7 to 10 ft). It is a sparingly branched shrub with smooth branchlets by flowering. The green leaves have an elliptic to egg-shape that is rarely undulate, 4.2 to 8.5 centimetres (1.7 to 3.3 in) long and 13 to 23 millimetres (0.51 to 0.91 in) wide. The leaves have one to three longitudinal veins on the top and three to five underneath, tapering at the base, smooth edges and gradually tapering at the apex. The inflorescence consists of 10-16 white flowers in a cluster of 1-3 per leaf axil. Flowering occurs from July to September. The pedicel are smooth, the perianth white and pistil 5–6.3 mm (0.20–0.25 in) long. The fruit are smooth, egg-shaped and taper to an upward curving beak, 1.6–2.5 cm (0.63–0.98 in) long and 0.9–1.8 cm (0.35–0.71 in) wide.^[2][3]

The species was first formally described by the botanist Carl Meissner in 1845 as part of Johann Georg Christian Lehmann's work Proteaceae. Plantae Preissianae.^[4][5] The specific epithet means "Loranthus-leaved".^[6]

It is endemic to an area in the Wheatbelt region of Western Australia between Northam in the north down to Narrogin in the south. It is found in sandy gravelly soils often around laterite.^[2] It is often found on and around breakaways and is a part of the understorey in open Eucalyptus wandoo and Eucalyptus accedens woodland communities.^[3]
