Description
Summary:Sabulina rubella (Wahlenberg) Dillenberger & Kadereit Figure 6D Materials examined. CANADA – Nunavut • Ellesmere Island, CFS Alert; 82°26′22″N, 062°50′39″W; 201 m a.s.l.; 7 Aug. 2019; habitat: barren ground in a slope, with till and rocks as substrates; QFA0635573. Identification. Plants 1.5–3.5 cm high; herbaceous; caespitose. Taproots present. Stems 0.8–2.5 cm long; prostrate, decumbent, or ascending; hairy, with glandular hairs. Leaves cauline; opposite; sessile. Leaf blades 3.0– 5.7 mm long, 0.5–1.0 mm wide; lanceolate or linear; straight or acending; veins 3; green; abaxial and adaxial surfaces both glabrous; margins ciliate, with glandular hairs; apices acute or apiculate. Inflorescence a solitary flower. Pedicels hairy. Sepals 5; 2–3 mm long, 0.5–1.4 mm wide; lanceolate; purple or green, with hyaline margins; surface glabrous or hairy, with glandular hairs; margins glabrous; apices acute. Petals 5; 2–3 mm long, 1.0– 1.5 mm wide; oblanceolate or obovate; unlobed; white. Androecium with 10 stamens and 0.2–0.3 mm long, yellow anthers. Gynoecium with 3 styles and 1 stigma per style. Fruit a capsule; 2.8–3.0 mm long, 1.4– 1.6 mm wide; ovoid or conical; straw-colored; glabrous. Characteristics allowing to distinguish S. rubella from the other Sabulina species present on Ellesmere Island can be found under S. rossii.
