Endemic. New Zealand: South Island (south Canterbury (Kirkliston Range, Hawkdun Range) and Otago (Dunstan Range)
Alpine in bogs and flushes in alpine grasslands and herbfields on low relief ridge tops
Plants annual, monocarpic, annual, 6-25 mm tall in flower. Caudex unbranched. Taproot slender. Flowering stems terminal only or terminal and lateral, 1–4 per plant, stem colour yellow, lateral flowering stems erect or decumbent, c.0.7-0.6 mm diameter; flowering stem leaves 1–2 pairs per stem, lowest pedicels from near apex of flowering stem. Rosette of leaves absent from flowering plants, leaves linear or narrowly elliptic, 1.5–13 × 0.5–2.0 mm, flat, not recurved, petiole indistinct, 2–7 mm long, 0.4–0.6 mm wide at leaf base. Flowering stem leaves narrower than leaves. Pedicels 0.7–1.7 mm long, c. 0.5 mm diameter. Flowers 1–4 per plant, 3.7–5.0 mm long. Calyx 4–5-lobed, 2.4–6.2 mm long, green tinted purple-black, hairs at calyx–corolla fusion line absent; lobes 1.0–3.3 mm long, 0.95–2.1 mm wide at base, plane, apices acute, margins smooth, sinus hairs absent. Corolla 3.4–4.3 mm long, white, veins uncoloured; tube 1.4–3.2 mm long; 4–5-lobed, lobes 2.0–3.6 mm long, 1.3–2.3 mm wide, hairs below sinus absent; nectary 0.6–1.0 mm from corolla base. Filaments 1.9–4.1 mm long from corolla base, 0.2–0.3 mm wide. Anthers 0.4–0.7 mm long, introrse at anthesis. Ovules 2–13 per ovary. Capsule 4.0–6.0 mm long.
Easily distinguished from other Gentianella by its annual growth habit; very small size; and usually by the presence of a single terminal, mostly 4-merous flower (though on occasion there may be up to four flowers present). It most closely resembles G. filipes which is endemic to north-west Nelson in size. In Otago cushion bogs it could be confused with G. amabilis. From which it differs by being an annual, rather than a perennial, by its parts being very much smaller and by the flat rather than V-shaped leaves.
