Name derivation:
Glischrocaryon from the Greek 'glischros' meaning gluey, clammy, slippery and 'caryon' meaning a nut; referring erroneously to the genus having succulent fruit when it was thought to belong to the Family Santalaceae, several species of which do have succulent fruits. Angustifolium from the Latin 'agustus' meaning narrow and 'folium' meaning leaf.
Distribution:
Found on the Eyre Peninsula and in the north-western corner in South Australia, growing on sandplains, sandy rises and dunefields. Also found in Western Australia and the Northern Territory.
Status:
Native. Common in South Australia. Uncommon in the Northern Territory. Common in Western Australia.
Plant description:
Multi-stemmed perennial herb to 65 cm high, with glabrous and often grey- or bluish-green stems and leaves. Juvenile leaves terete, to 7 mm long and 0.5 mm wide, crowded, channelled above. Adult leaves alternate, sometimes much reduced and scale-like, sessile, linear to linear-lanceolate, flat, to 40 mm long and 1.5 mm wide, with entire margins. Inflorescence terminal clusters with 7-31 yellow to yellow-green flowers. Flowering between August and December.
Fruit type:
Yellow or reddish-tinged pear-shaped papery fruit to 11.5 mm long, glabrous with 4 longitudinal wings.
Seed type:
Brown ovoid seed to 4 mm long and 2 mm wide with a tuberculate surface texture.
Seed collecting:
Collect fruit that have developed wings and the seed in the middle is hard.
Seed cleaning:
Place the fruit in a tray and leave to dry for a week or two. Seeds can be stored with the wings or you can rub the dried fruit with a rubber bung to dislodge the seeds. Use a sieve to separate any 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 viability:
From one collection, the seed viability was high, at 85%.
