Triglochin nana F.Muell.

Defin. Austral. Pl. 53 (1855)

Taxonomic status:Accepted

Occurrence status:Present

Establishment means:Native

Slender annual herb, (2–)4–12 cm high. Leaves flat and thread-like, 1–6 cm long, shorter than to almost as long as the infructescence. Scape at fruiting erect or ascending, (1–)1.5–5.5 cm long; infructescence (0.5–)1–3(–5) cm long, with (3–)5–16(–24) fruits. Fruits narrowly pyramidal, (2.2–)3–4.5 mm long, 0.5–1.2 mm wide just above base; pedicel 0.5–2.5(–3) mm long; carpels 6, 3 fertile carpels alternating with 3 undeveloped sterile ones; fertile carpels flat to keeled or slightly convex dorsally when dry, at base with 2 lateral acute or obtuse points 0.1–0.5 mm long. Fruits Aug.–Nov.

Triglochin nana is a widespread and variable species, and it its extremes may easily be confused with T. isingiana, T. longicarpa and T. minutissima. From the latter two, T. nana is generally distinguished by the presence of spurs on fruits, and from T. isigniana it may be distinguished by the shorter carpel spurs and flattened fruits. However, plants appear to grade from spurs that are near-absent to long-spurred, and boundaries of these four species may prove to be unsatisfactory.
