Common Name: JEWELFLOWER Habit: Annual to perennial herb, generally +- glaucous; hairs simple or 0. Leaf: basal rosetted or not, petioled, entire or dentate to pinnately lobed or divided; cauline sessile, occasionally petioled, base generally lobed or clasping. Inflorescence: open, elongated, bracts 0 or bracted below proximal 1--2 flowers, sometimes with sterile flower cluster. Flower: radial or bilateral; calyx urn- or occasionally bell-shaped, sepals erect, base +- sac-like, keeled or not; petal blade narrower to wider than proximal 1/2, generally channeled, margins +- crinkled or not; stamens in 3 pairs of unequal length, or 4 long and 2 short, longest filaments fused or free. Fruit: silique, dehiscent, linear, flat parallel to septum, unsegmented; stigma entire or 2-lobed. Seed: 10--120, in 1 row, generally winged.

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.
