Habit: [Annual] perennial herb, hairs +- many-branched, tree-like. Leaf: basal simple, entire or dentate to deeply lobed; distal cauline sessile, base wedge-shaped to truncate (lobed). Inflorescence: elongated or not. Flower: sepals erect, base not sac-like; petals oblanceolate to spoon-shaped, not clawed, white. Fruit: silique [silicle], dehiscent, unsegmented, linear [ovate to oblong], flat parallel or perpendicular to septum, hairy, hairs small +- sessile, some long-stalked; stigma entire. Seed: 16--110, in 1[2] rows, oblong, wingless. Etymology: (Greek: sea pod, from resemblance of fruit hair cover to salt) eFlora Treatment Author: Ihsan A.

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.
