Name derivation:
Correa named after Jose Francisco Correa de Serra (1751-1823), a Portuguese botanist. Glabra from Latin meaning smooth, without hairs. Leucoclada from the Greek 'leucos' meaning white and 'klados' meaning a branch; referring to a covering of white down which easily rubbed off on the young shoots.
Distribution:
Found in the southern Mount Lofty ranges in South Australia, growing in hilly situations along banks of streams. Also found in New South Wales.
Status:
Native. Rare in South Australia. Common in New South Wales.
Plant description:
Erect shrub to 3 m high with hairy to glabrous stems. Leaves narrow- to broad-elliptic or occasionally obovate, to 4 cm long and 17 mm wide, apex obtuse to rounded, base rounded to cuneate, upper surface smooth or sparsely hairy, lower surface densely hairy. Inflorescence solitary, terminal on short axillary shoots with tubular pale green flowers. This variety differ from Correa glabra var. turnbullii having pale green flowers rather than red and from C. glabra var. glabra by having tomentose leaves below and tomentose cup-shaped to shortly cylindrical calyx rather than glabrous or glabrescent leaves and glabrous or glabrescent, hemispherical calyx.
Fruit type:
White to green capsule to 8 mm long enclose by the sepals.
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 sepals.
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.
