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

MAP CONTROLS 1. You can change the display of the base map layer control box in the upper right-hand corner.
2. County and Jepson Region polygons can be turned off and on using the check boxes.
(Note: any qualifiers in the taxon distribution description, such as 'northern', 'southern', 'adjacent' etc., are not reflected in the map above, and in some cases indication of a taxon in a subdivision is based on a single collection or author-verified occurrence).
MAP LEGEND View all CCH records All markers link to CCH specimen records. The original determination is shown in the popup window.
Blue markers indicate specimens that map to one of the expected Jepson geographic subdivisions (see left map). Purple markers indicate specimens collected from a garden, greenhouse, or other non-wild location.
Yellow markers indicate records that may provide evidence for eFlora range revision or may have georeferencing or identification issues.
