Name derivation:
Viola from Latin for violet, referring to the violet genus. Cleistogamoides means having a cleistogamous (from the Greek Greek 'kleistos' meaning closed) mode of pollination; having small, unopened, self-pollinating flowers, usually in addition to the showier flowers.
Distribution:
Found in the Mount Lofty Ranges and the lower South-east in South Australia, ground on sand or skeletal soils in west heathland and woodland. Also found in New South Wales, Victoria and Tasmania.
Status:
Native. Rare in South Australia. Rare in New South Wales. Common in the other states.
Plant description:
Perennial stoloniferous herb, glabrous or weakly pubescent withshort erect stems. Leaves tufted, glabrous or weakly pubescent, leaf-blade broadly ovate to ovate-rhomboid, margins with a few coarse teeth, tapering to the petiole. Flowers cream, often with a purplish tinge towards the centre on a short stalk. Flowering between October and January.
Fruit type:
Brown ovoid capsule to 4 mm long.
Seed type:
Black ovoid seed to 2 mm long and 1.3 mm wide.
Embryo type:
Spatulate fully developed.
Seed collecting:
Collect capsules that are maturing, drying and turning pale brown with brown seeds inside. Keep an eye on the capsules as they can ripen and split open quickly.
Seed cleaning:
Place the capsules in a tray and cover with paper to prevent seeds popping out and leave to dry for a week. Then rub the capsules gently  with your hands to dislodge the seeds. Use a sieve to separate the 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 average, at 55%.
Seed germination:
This species has physiological dormancy that need to be overcome for the seed to germinate.
