Name derivation:
Utricularia from the Latin 'utriculus' meaning a small bottle or bladder; referring to a small insect trapping sac attached to the underground leaves. Barkeri named after Dr William (Bill) R. Barker, former Chief Botanist of the State Herbarium of South Australia, who has made significant contributions to Australian botany with studies of Australasian Scrophulariaceae and various other families.
Distribution:
Found on Kangaroo Island and the South-east in South Australia, growing lowland swampy heaths. Also found in Victoria and Tasmania.
Status:
Native. Rare in South Australia. Uncommon in the other states. Possible more common due to confusion with Utricularia dichotoma.
Plant description:
Tiny terrestrial herb. Leaves few, basal to flowering stem and on stolons, linear to narrowly obovate to ovate or spathulate, to 12 mm long and 0.6 mm wide. Inflorescence solitary, erect, to 28 cm long, with 1 to 3 light mauve flowers, upper lip oblong, distinctly constricted about the middle, lower lip much larger, fan-shaped. Flowering between October and January.

This species differs from Utricularia dichotoma with presence of basiolute bracts with upper and lower lobes

of equal length and corolla upper lip light mauve with purple flecks.

Fruit type:
Reddish brown globular capsule to 3.5 mm diameter.
Seed collecting:
Collect mature capsules, those turning reddish brown colour, fat and containing brown seeds. Can collect individual capsules or break off the whole stem.
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.
