Census of South Australian plants (external link)     [genus Glycine]
Name derivation:
Glycine from the Greek 'glykys' meaning sweet; referring to the sweet roots and leaves of some species of the Glycine (soybean) genus. Canescens from the Latin 'canescens' meaning becoming hoary (white or greyish in colour), referring to the silky hairs giving the plant a hoary appearance.
Distribution:
Found across the northern part of South Australia, growing on sandy or stony soil. Also found in all mainland states.
Status:
Native. Common in South Australia. Very rare in South Australia. Common in the other states.
Plant description:
Twining perennial herb  with non-stoloniferous stems, covered in silky hairs, hoary. Leaves pinnately 3-foliolate, leaflets elliptic-linear to narrow oblong-lanceolate, to 80 mm long and 12 mm wide. Inflorescence a raceme with 6-12 pinkish purple or mauve, fading to blue pea-flowers, arranged loosely and distally on the rhachis. Flowering between July and August.
Fruit type:
Silky, slightly compressed, linear pod to 35 mm long and 4 mm wide with 5-7-seeded.
Seed type:
Black rectangular seed to 3 mm long and 1.5 mm wide, with a wrinkled surface.
Embryo type:
Bent.
Seed collecting:
The pods of this pea change colour from pale green to a dark brown when mature. The seed pods twist and burst apart expelling the seeds when fully ripe so timing of seed collections is important. Monitor fruits closely, bag maturing fruits or place groundsheets under plants to catch seeds . Alternatively, the pods can be harvested close to maturity (when they turn brown) and fully dried in a warm area.
Seed cleaning:
Place the pods in a tray and cover with paper to prevent seeds popping out and leave to dry for a week. Then rub the dried pods 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 germination:
This species has physical dormancy that needs to be overcome for the seed to germinate (e.g. nicking or softening the seed coat).
