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.
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.
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.
