Hakea named after Baron Christian Ludwig von Hake (1745-1818), a German horticulturalist and patron of botany. Carinata presumably from the Latin ' carina' meaning keel, however, it is not clear what is keeled in the original description of the species, but may refer to the trigonous leaves of this species, or the base of the fruit.
Distribution and status
Endemic to South Australia and found in the southern Flinders Ranges, Mount Lofty Ranges and the upper South-east growing in the dry sclerophyll forest and in scrub-heath, in sandy to loamy soil. Native. Common in South Australia.
Herbarium regions: Flinders Ranges, Northern Lofty, Murray, Southern Lofty, South Eastern

Erect untidy shrub to 3 m tall. Leaves broadly to narrowly linear, flat, concave or trigonous to 240 mm long and 12 mm wide; glabrous, marginal veins prominent; midvein only, or sometimes 3 longitudinal veins prominent below. Inflorescence a solitary axillary umbel with 8–24 cream-white flowers becoming pink with age. Flowering between September and October. Fruits are greyish-brown woody ovoid fruit to 26 mm long and 11 mm wide, with a long pointed tip. After fire or when warm enough, the fruit splits into two to reveal two seeds. Seeds are dark-brown to black ovoid seed to 5 mm long and 3 mm wide (12 mm long and 5 mm wide including the wing that extends narrowly down both sides of seed). Seed embryo type is investing.
Seed collection and propagation
Collect seeds between January and December. Collect mature woody fruit that are greyish-brown and not split. These will contain 2 seeds. Place the woody fruit in a tray and leave to dry until it splits open. Fruits can be placed in the oven at low temperatures to achieve the same result. Place the dried fruit in a bucket and shake to dislodge the seeds from the valves. Separate the seeds from the fruit and store the seeds with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place. From one collection, the seed viability was high, at 90%. Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
