Leaves

overlapping proximally, perfoliate proximally, with ± loose, scarious to herbaceous sheath 0.5–1 mm;

blade green, flat, 1-veined, oblanceolate to cuneate (proximal) to oblong-lanceolate to ovate (remaining cauline), 5–30(–35) × 2–4 mm, flexuous, margins not thickened, ± scarious, smooth, apex green to purple, obtuse to abruptly pointed, dull, glabrous;

axillary leaves absent.

sometimes overlapping proximally, connate proximally, with ± loose, herbaceous sheath 0.2–0.4 mm;

blade widely spreading to erect, green, 1-veined abaxially, flat, narrowly elliptic (proximal petiolate blades) to linear (remaining cauline blades), 8–30 × 0.5–3 mm, flexuous, margins not thickened, scarious, occasionally stipitate-glandular, apex green, acute to acuminate, shiny, glabrous;

axillary leaves absent.

Inflorescences

7–12-flowered, open cymes, or rarely solitary, terminal;

bracts ± lanceolate, herbaceous, sometimes scarious-margined proximally.

3–5(–7)-flowered, open, leafy cymes;

bracts linear to lanceolate, herbaceous.

Pedicels

reflexed in fruit, 0.5–2.5 cm, stipitate-glandular.

1–5 cm, sparsely glandular.

Flowers

hypanthium disc-shaped;

sepals obscurely veined, ovate to broadly elliptic (herbaceous portion ovate to broadly elliptic), 3–6 mm, to 7 mm in fruit, apex green or purple, acute to acuminate, not hooded, stipitate-glandular;

petals obovate to oblanceolate, 2–2.5 times as long as sepals, apex rounded, broadly notched.

hypanthium disc-shaped;

sepals 3-veined, lanceolate (herbaceous portion linear-lanceolate to lanceolate), 3.5–5 mm, not enlarging in fruit, apex often purple, acute, not hooded, stipitate-glandular;

petals oblong-spatulate, 2.5–3 times as long as sepals, apex rounded, shallowly notched.

Discussion

Minuartia drummondii is easily recognized by the proportionally large corollas (petals to three times as long as sepals) and pedicels reflexing in fruit.

Of conservation concern.

Minuartia godfreyi is known from few, very widely scattered populations; it may be most closely related to M. patula and M. muscorum, sharing prominently ribbed sepals with both taxa and black, muriculate-papillate seeds with the latter (R. Kral 1983).
