Spergularia tasmanica (Kindb.) L.G.Adams

Australian Systematic Botany 21: 258, 259 APNI

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Annual to perennial; rootstock thick, woody; stems robust, more or less erect, 10–40 cm, flattened above. Leaves linear, flattened, mucronate to shortly awned, hardly fasciculate, fleshy, 10–60(–80)mm long, 1–2 mm wide, sparsely glandular-ciliate; stipules scarcely acuminate, (3–)4–6(–7)mm long, shortly connate in inflorescence, not silvery. Inflorescence lax, monochasial above; pedicels often reflexed in fruit, much longer than sepals, glandular-hairy. Flowers 7–10 mm diam.; sepals 4–7 mm long, with dense glandular hairs 0.l–0.25(–0.5) mm long; petals 1–2 mm shorter than sepals, pink; stamens 5–10. Capsules ovoid, 1–2 mm longer than sepals; seeds 0.7–1.1 mm long, prominently blunt-tuberculate, pitch-black, scariously winged or rarely some unwinged in same capsule, the wing-margin entire to erose-denticulate. Flowers mostly Oct.–Dec.

This species has a similar habit and favours a similar habitat to the adventive Spergularia media, but is readily distinguished by its black, tuberculate seeds (as opposed to the red-brown, smooth seeds of S. media). The taxon is so widespread in natural marine and inland saline wetlands, especially of south-eastern Australia and New Zealand, that it must be seriously considered native to Australasia.
