Dianthus
See list of 5 species in this genus-
1a. Plants with scattered, solitary flowers borne on slender pedicels 10–40 mm long [Fig. 559]; bracts subtending the flowers up to ½ as long as calyx [Fig. 559]
-
2a. Basal leaf blades oblanceolate, 15–30 mm long; at least the lower internodes of the stem puberulent; blade of petals 5–10 mm long, the apex toothed [Fig. 559]; calyx equaling the length of the fruit; bracts ca. 50% as long as the calyx
-
2b. Basal leaf blades linear, 20–80 mm long; stems glabrous; blade of petals 12–18 mm long, fringed-cleft to near the middle; calyx shorter than the length of the fruit; bracts 25–36% as long as the calyx
-
-
1b. Plants with closely crowded, sessile or short-pedicellate flowers borne in terminal cymes [Fig. 558]; bracts subtending flowers nearly equaling to exceeding the length of the calyx [Fig. 558]
-
3a. Calyx, including the basal connate portion, pubescent [Fig. 558]; plants annual or biennial; stems usually strigose below the nodes
-
3b. Calyx completely glabrous or only the lobes pubescent [Fig. 558]; plants perennial; stems glabrous (sometimes scabrous)
-
4a. Stem leaf blades lanceolate to oblanceolate, (10–) 15–25 (–30) mm wide, sheathing the stem for less than 3 times the stem diameter; calyx lobes glabrous
-
4b. Stem leaf blades linear, up to 5 mm wide, sheathing the stem more than 3 times the stem diameter; calyx lobes pubescent
