Name derivation:
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 the original description of the species, but may refer to the trigonous leaves of this species.
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.
Plant description:
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, pink with age flowers. Flowering between September and October.
Fruit type:
Greyish-brown woody ovoid fruit to 26 mm long and 11 mm wide, with a long pointy end. Fruit split into two to reveal two seeds.
Seed type:
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 extend narrowly down both sides of seed).
Embryo type:
Seed collecting:
Collect mature woody fruit that are greyish-brown and not split. These will contain seeds.
Seed cleaning:
Place the woody fruit in a tray and leave to dry until it split 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.
Seed viability:
From one collection, the seed viability was high, at 90%.
Seed germination:
Seeds are non-dormant, viable seed should germinate readily without pre-treatment.
