Bulbine from the Latin 'bulbous' meaning a bulb, referring to the bulb-shaped tuber of many members of this genus. Semibarbata from the Latin 'semi' meaning half and 'barbata' meaning bearded, referring to half of the filaments being bearded.
Distribution and status
Found scattered across South Australia but more common in the central part, especially on Eyre Peninsula, growing on sand, sandy clay, or loam in areas that are wet in winter, such as granite outcrops, creek lines, the margins of salt lakes and along the coast. Also found in Western Australia, Queensland, New South Wales, Victoria and Tasmania. Native. Common in South Australia. Common in the other States.

Erect annual herb to 20 cm tall with cylindrical fleshy basal leaves. Inflorescence a long erect spike with yellow flowers, with the 3 longer inner perianth filaments bearded and 3 other filaments short and glabrous. Flowering between September and November. Distinguished from the other Bulbine species by not having a tuber, no wing around the seeds and half of perianth filaments bearded. Fruits are round capsules less than 5 mm long, containing numerous seeds. Seeds are brown pyramid-shaped seeds to 3mm long with a bumpy surface. Seed embryo type is linear fully developed.
Seed collection and propagation
Collect seeds between October and December. Collect mature capsules, those that are turning a pale straw colour and contain brown seeds. Can collect individual capsules or break off the whole fruit spike. 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 is usually high.
