Common Name: CENTAURY
Habit: Annual, glabrous. Stem: erect, generally branched. Leaf: cauline, opposite (sometimes also basal). Inflorescence: cyme. Flower: parts in 4s or generally 5s; calyx lobes >> tube (discounting thin membrane between lobes in Zeltnera davyi), appressed to corolla tube, generally not keeled; corolla salverform, white or generally pink, lobes <= tube, +- entire, scales 0, nectaries pits 0 (nectaries elsewhere 0); stamens often initially curved to 1 side, dehisced anthers spirally twisted; ovary sessile, style generally thread-like, deciduous, entire or cleft < 1 mm, stigmas 1, 2-lobed, or 2, stigmas or lobes wedge- to fan-shaped.

Zeltner, Swiss botanists, b. 1938, 1934) Note: Variable, difficult; further study needed, especially of chromosome numbers, hybridization. Zeltnera calycosa (Buckley) G. Mans.
