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. Flavescens from the Latin 'flavus' meaning yellow and the suffix '-escens' meaning in the process of becoming, referring to its flowers, which are paler than other species.
Found on the north-eastern Eyre Peninsula, Flinders Ranges and northern Mount Lofty Ranges in South Australia growing on sandy or clay, often stony soils in rocky hillsides and plains. Also found in Western Australia.
Native. Common in South Australia. Common in Western Australia.

Robust perennial herb to 90 cm high with numerous thick pithy stems to 8 mm diameter. Leaves linear to narrow-lanceolate to 30 mm long and 3 mm wide, tapering gradually to the tip; often deciduous. Inflorescence of terminal clusters with 31 pale yellow to cream flowers. Flowering between August and December.
Fruit type:

Seed collecting:

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 95%.
