Leaves shortly petiolate, rarely subsessile; lamina 3–26 × 2–17 mm., variable in shape and size, ovate, or elliptic to oblong or linear-oblong or obovate, rounded at the apex, cuneate or rounded at the base, with numerous translucent glandular dots sometimes varying in size and ± prominent and yellowish, and dark glandular dots round the margin and occasionally elsewhere.
A herb that keeps growing from year to year. The stems often lie along the ground. It forms tufts. The stems arise from corms or roots that lie parallel to the ground. It grows 10-60 cm high. The leaf blade is 3-26 mm long by 2-17 mm wide. They vary in shape. The flowers are at the end of the stems. The petals are bright yellow or red. The fruit is fleshy and round.
Stems prostrate to procumbent or ascending, rarely ± erect, tufted, usually ± slender, ± branched, arising from an underground crown or sometimes from adventitious buds on the horizontal roots, (5) 10–60 (90) cm. long (usually less than 30 cm. in our area), terete or sometimes slightly 2-lined above, spotted with dark glands (or eglandular outside our area).
Sepals elliptic obovate or oblong, obtuse, unequal or very unequal, the inner ones usually much narrower, with a varying number of translucent glandular dots and dark glandular dots which are usually submarginal only but may also occur elsewhere.
Petals (5) 7–8 (14) mm. long, 11/2–2 times as long as the sepals, primrose to bright yellow, often red-tinged, with dark glandular dots usually confined to the margin (very rarely also dispersed over part of the lamina).
Stamens c. 20–10 (60), irregularly arranged or in 3, 4 or 5 indistinct groups, with filaments ± united at the base; anthers with a dark gland at the end of the connective.
Flowers terminal in few-flowered cymes or solitary, often apparently axillary; pedicels 5–40 mm. long, ± reflexed in fruit.
Ovary 4–5-locular; styles 5, less frequently 4, free, 1–4 mm. long.
Fruit fleshy, usually subglobose or broadly ovoid, indehiscent.
Herb of mountain grasslands, often in moist places
