Name derivation:
Correa named after Jose Francisco Correa de Serra (1751-1823), a Portuguese botanist. Eburnea from the Latin 'eburneus' meaning ivory-white; referring to the colour of the lower leaf surface.
Endemic to South Australia and found on the southern Fleurieu Peninsula, growing on banks of damp creeks.
Native. Very rare in South Australia.
Plant description:
Shrub to 4 m high with slender and rusty-coloured hairy branches, sometimes flexuose towards apex. Leaves elliptic to ovate, entire, mostly to 5 cm long, papery, flat, smooth, sparsely pubescent above when young, glabrous at maturity, minutely hairy beneath, obtuse, rounded to slightly cordate at base. Flowers axillary, with 1-5 nodding, tubular, green flowers. Flowering between October and January.
Fruit type:
Brown capsule enclose by the sepals.
Seed type:
Mottled brown ovoid seed to 8 mm long and 3 mm wide, smooth surface. 
Embryo type:
Linear fully developed.
Seed collecting:
Collect mature capsules, those that are turning a pale straw colour and contain hard seeds, either by hands or place small breathable bags over immature capsules to collect seed. Capsules maybe hard to see as it is enclose by the green sepals.

Seeds for this endemic Correa species are being collected and banked in 2017, supported by Natural Resources Adelaide & Mount Lofty Ranges

Seed cleaning:
Place the capsules in a tray and leave to dry for a weeks. Then rub the capsules gently by hand to dislodge the seeds. Be very careful as the seed coat is thin and easily damaged. Use a sieve to separate the unwanted material. 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 germination:
This species has morphophysiological dormancy and can be difficult to germinate.
