Name derivation:
Vallarsia named after Dominique Villars (1745-1814), a French botanist and physician. Umbricola from the Latin 'umbra' meaning shady and 'cola' meaning dwelling; referring to its habit in damp soils or shallow fresh water in semi-shaded and sheltered sites. Beaugleholei named after Alexander Clifford (Cliff) Beauglehole (1920–2002), an Australian farmer, botanist, plant collector and naturalist.
Distribution:
Found in the lower South-east in South Australia, growing on damp sandy or peaty soil or in shallow fresh water in semi-shaded sites of forest depressions, bogs and creek edges. Also found in Victoria.
Status:
Native. Very rare in South Australia. Common in Victoria.

Leaves erect, ovate to almost circular, to 12 cm long, entire, rounded to moderately cordate at the base. Inflorescence a a lax slender panicle occupying much of the flowering stem, with large yellow flowers. This variety differ from the other variety found in South Australia, Vallarsia umbricola var. umbricola which have smooth or slightly granular seeds. Flowering between November and April.
Fruit type:
Pale brown papery capsule to 11 mm long.
Seed type:
Orange ellipsoid seed to 1.3 mm long and 1 mm wide, with a strongly tuberculated surface.
Seed collecting:
Collect mature capsules, those that are turning a pale straw colour and contain hard seeds. Can collect individual capsules or break off the whole fruit spike.
Seed cleaning:
Place the capsules in a tray and leave to dry for two weeks. Then rub the capsules gently by hand 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 high, at 95%.
