Sabulina rossii (R. Brown ex Richardson) Dillenberger & Kadereit Materials examined. CANADA – Nunavut • Ellesmere Island, CFS Alert; 82°27′34″N, 062°44′57″W; 118 m a.s.l.; 16 Aug. 2019; habitat: xeric, with polygonal patterned ground made of till and rocks, and sparse dominance of Juncus biglumis Linnaeus and moss; QFA0635571. Identification. Plants 1–3 cm high; herbaceous; caespitose. Taproots present. Stems 0.5–1.5 cm long; prostrate, decumbent, or ascending; glabrous. Leaves cauline; opposite; sessile. Leaf blades 2–3 mm long, 0.3–1.0 mm wide; elliptic or linear; upwardly curved; appearing single-veined or veins inconspicuous; green, dark purple, or dark red; abaxial and adaxial surfaces both glabrous; margins glabrous; apices obtuse. Inflorescence a solitary flower. Pedicels glabrous. Sepals 5; 1.0– 2.8 mm long, 0.5–1.3 mm wide; ovate; purple; surface glabrous; margins glabrous; apices obtuse or acute. Petals 5; 2–3 mm long, 0.7–1.2 mm wide; oblong or obovate; unlobed; white. Androecium with 10 stamens and 0.4–0.5 mm long, yellow anthers. Gynoecium with 3 styles and 1 stigma per style. The only two Sabulina Reichenbach species present on Ellesmere have been found in our survey (Aiken et al. 2007; GBIF 2020). They differ in a few characters: S. rossii has glabrous stems, whereas S. rubella has pubescent stems with glandular hairs (Blondeau et al. 2015b; Saarela et al. 2020), and S. rossii has single-veined (if vein apparent) leaf blades,whereas S. rubella has threeveined leaf blades (Aiken et al. 2007). : Published as part of Desjardins, Émilie, Lai, Sandra, Payette, Serge, Dubé, Martin, Sokoloff, Paul C., St-Louis, Annie, Poulin, Marie-Pier, Legros, Jade, Sirois, Luc, Vézina, François, Tam, Andrew & Berteaux, Dominique, 2021, Survey of the vascular plants of Alert (Ellesmere Island, Canada), a polar desert at the northern tip of the Americas, pp. 181-225 in Check List 17 (1) on page 196, DOI: 10.15560/17.1.181 : {"references": ["Aiken SG, Dallwitz MJ, Consaul LL, McJannet CL, Boles RL, Argus GW, Gillett JM, Scott PJ, Elven R, LeBlanc MC, Gillespie LJ, Brysting AK, Solstad H, Harris JG (2007) Flora of the Canadian Arctic Archipelago: descriptions, illustrations, identification, and information retrieval.
