SA Census:
Census of South Australian plants (external link)     [genus Enchylaena]
SA Flora:
Flora of South Australia Edition 5
Name derivation:
Enchylaena from the Greek 'egchlos' meaning fleshy, succulent and 'laina' meaning lined cloak, alluding to the succulent fruiting perianth. Tomentosa from the Latin 'tomentum' meaning wool, hair, referring to the hairs on the plant.
Distribution:
A widespread species found across South Australia in a variety of habitats. Occurs principally in slightly saline soil.
Status:
Common.
Plant description:
Shrubby perennial to 1m high, branches decumbent to erect, tomentose. Leaves semiterete, succulent to approximately 15mm long, villous. Inconspicous small flowers, solitary, emerging from the axis of the leaf and stem. Flowering May-November.
Fruit type:
Fruiting perianth depressed-globular, flat to deeply sunken in the centre; wing absent or crown-like and incurved; lobes glabrous (but ciliolate) to pubescent. Approximately 5mm in diameter, green, yellow or red (drying brown to black).
Seed type:
Seeds are black/brown and disc shaped, up to 1.5 mm diameter with overlapping embryo tip sometimes forming a small beak.
Embryo type:
Peripheral.
Seed collecting:
Collect the fruits by running gloved fingers through branches to remove mature or drying fruits. Collect when fruit is red and seed inside is brown and firm.
Seed cleaning:
Soak the fruit in 1% pectinase and water solution for at least 4 hours. Then gently rub the soaked fruits through a sieve to remove the fleshy and leave the remaining seeds to dry. Store the dried fruit heads with a desiccant such as dried silica beads or dry rice, in an air tight container in a cool and dry place.
Seed germination:
Germination 100%, seed scarified (covering structure removed) on 1% w/v agar, 12/12 dark/light, 23°C/9°C. See http://data.kew.org/sid
