See list of 4 species in this genusReference: Pringle (2005).
-
1a. Pedicels and sepals glandular-puberulent; leaf blades clasping at the base; apical portion of stem glandular-puberulent
-
1b. Pedicels and sepals not glandular-puberulent [Fig. 560]; leaf blades not clasping (basal leaves clasping in G. elegans); apical portion of stems glabrous (sometimes the stems pubescent with eglandular or glandular hairs, but then the hairs usually confined to the basal half)
-
2a. Slender annuals with green stems 0.4–3 (–4) dm tall; leaf blades linear, 0.2–2 (–3) mm wide; capsule oblong
-
2b. Stout annuals or perennials with glaucous stems 2–10 dm tall; leaves lanceolate, (1–) 2–16 mm wide; capsule spherical
-
3a. Plants perennial; petals 1–4 mm long; calyx 1–3 mm long, slightly shorter to nearly as long as the petals; longer pedicels 0.5–12 mm long
-
3b. Plants usually annual; petals 6–15 mm long; calyx 2.5–5 mm long, ca. 36–50% as long as the petals; longer pedicels 10–35 mm long
