Descriptions
Perennial; stems us. several to many, margined, stout, trailing or prostrate, us. much-branched; branches very lfy, ± 20-45 cm. long, ascending to suberect at tips. Basal lvs coriac., fleshy, shining; lamina obovate- to spathulate-oblong to linear-spathulate, (12)-20-40 × 8-10 mm., with 3 evident nerves, narrowed to broad flat petiole. Cauline lvs similar, 6-36 mm. long, on very short petioles. Fls several together, approximate, near ends of branches, 8-16 mm. long, sts laxly corymbose, subsessile or on very short slender pedicels. Calyx < or - corolla, cut 3/4 way or more into oblong or spathulate, obtuse, often recurved lobes. Corolla white or ± streaked with red or purple veins, broadly rotate-campanulate with oblong obtuse lobes c. 7 mm. wide.
Stems up to c. 45 cm. long, slender, decumbent at base, then suberect. Lvs spathulate-oblong, us. petiolate; cauline more remote. Fls us. in rather lax corymbose cymes. Calyx-lobes broad-oblong.
Gentianella cerina (Hook.f.) T.N.Ho & S.W.Liu
Plants polycarpic, height in flower 90–170 mm. Caudex unbranched or branched, 110–200 mm long. Flowering stems terminal only or terminal and lateral, 3–12 per plant, 1.1–3.1 mm diam. when dry, lateral flowering stems decumbent, flowering stem leaves 3–4 pairs per stem (not applicable in cases where no rosette is present on multi-branched plants), lowest pedicels from halfway up flowering stem to near apex of flowering stem. Rosette of leaves absent, not very distinct, or distinct from flowering plants leaves; leaves narrowly elliptic, 36.6–53.1 mm long, 8.4–12.6 mm wide, flat, not recurved, margins thickened, apex rounded and retuse; petiole distinct, 11–13 mm long, 4.7–6.3 mm wide at leaf base. Flowering stem leaves the same but smaller. Pedicels 1 or 2 per leaf axil, 6.2–17.8 mm long, 1.2–1.3 mm diam., 0.7– 1.0 mm diam. when dry. Flowers 15 to more than 100 per plant, 9.9–14.1 mm long. Calyx 9.3– 12.2 mm long, hairs at calyx–corolla fusion line present; lobes 7.5–10.3 mm long, 2.4–3.4 mm wide at base, plane, apices obtuse (widest near the apex), margins smooth, sinus hairs absent. Corolla 8.4– 11.8 mm long, white or tinted red to purple, veins colourless or purple; tube 2.1–4.4 mm long; lobes 6.3–8.8 mm long, 3.8–5.0 mm wide, hairs below sinus absent or present; nectary 1.2–1.5 mm from corolla base. Filaments 4.9–6.9 mm long from corolla base, 0.70–0.85 mm wide. Anthers 0.9– 1.7 mm long, extrorse at anthesis; pollen yellow. Stigma purple or colourless. Ovules 13–37 per ovary. Capsule 6.5–12 mm long. FL (Dec–)Jan– Mar(–Apr).
