See list of 6 species in this genusReference: Pennell (1929).
-
1a. Corolla pink, becoming pale in drying; calyx tube reticulate-veined [Fig. 747]; plants persistently yellow-green, even in drying
-
1b. Corolla purple to pink-purple (rarely white); calyx tube scarcely, if at all, veiny [Fig. 748]; plants generally dark green and often purple-tinged in life, darkening in drying
-
2a. Lobes of the calyx oblong or semiorbicular, obtuse to rounded at the apex [Fig. 748]; anther cells obtuse to subacute at the base; plants fleshy, of coastal saltmarshes
-
2b. Lobes of the calyx triangular to subulate, acute to acuminate at the apex; anther cells mucronate to caudate at the base; plants not fleshy, predominantly not of coastal saltmarshes (except sometimes in A. purpurea)
-
3a. Lobes of the calyx 1.8–5 mm long, 0.75–2 times as long as the basal, connate portion; pollen sacs ca. 1 mm long; style 4–5 mm long
-
3b. Lobes of the calyx 0.3–3.5 mm long, 0.2–1 times as long as the basal, connate portion; pollen sacs 1.4–2.2 mm long; style 8–14 mm long
-
4a. Pedicels 10–20 mm long at anthesis; corolla glabrous on the adaxial (i.e., inside) surface, the upper lip arched forward over the stamens
-
4b. Pedicels 1–8 mm long at anthesis; corolla pubescent on the adaxial surface (i.e., inside), the lobes of the upper lip reflexed-spreading
-
5a. Corolla 10–20 (–23) mm long; calyx lobes 2–3.5 mm long, 0.4–1 times as long as the basal, connate portion; style 6–10 mm long
-
5b. Corolla 20–38 mm long; calyx lobes 0.5–2 mm long, up to 0.5 times as long as the basal, connate portion; style 15–20 mm long
