Name derivation:
Glycine from the Greek 'glykys' meaning sweet; referring to the sweet roots and leaves of some species of the Glycine (soybean) genus. Rubiginosa from the Latin 'rubiginosus' meaning rusty-red, alluding to the calyx hairs.
Distribution:
Found mainly in the central part of South Australia, with scattered occurrences in west, growing in grasslands and grassy woodlands. Also found in Western Australia, Northern Territory and New South Wales.
Status:
Native. Common in South Australia. Rare in the other states.
Plant description:
Perennial twining herb with non-stoloniferous stems covered in white to rusty hairs. Leaves digitately 3-foliolate, leaflets sessile or subsessile, commonly oblong-lanceolate, but occasionally elliptic to broadly elliptic or linear, to 40 mm long and 10 mm wide, apex acuminate, upper surface glaborous, lower surface with sparse, appressed white to rusty hairs. Inflorecence a raceme to 12cm long, with mauve to purple pea-flowers, calyx moderately to densely hairy with dark brown hairs. Flowering between July and November.
Fruit type:
Brown linear to short-oblong pod to 30 mm long and 4 mm wide, margins slightly thickened, covered in white or rusty hairs.
Seed type:
Smooth, olive-black with dark stripes to a dark brownish-red, ovoid to suborbicular seed to 2.5 mm and 1.5  mm wide.
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). Germination 100%, seed scarified (chipped with scalpel), on 1% w/v agar, 8/16 dark/light, 15C/30C. See http://data.kew.org/sid
