Plant Description

Biennial or short-lived perennial from growing from a simple crown, the stem usually single, simple or branched above, 3-15 dm. tall, The plant is pubescent with stiff, simple hairs at the base, becoming glabrous above. Leaves are mainly cauline: the basal ones oblanceolate, 3-14 cm. long, usually remotely toothed, the blade narrowed to a short, winged, greenish petiole. Leaves are pubescent with a mixture of simple and stellate hairs. The Inflorescence is a many-flowered raceme with slender pedicles. Flowers feature 4 sepals, with 4 cream colored petals. Fruits are glabrous, 1-nerved siliques, 6-10 cm. long and 1-1.5 mm. broad.

Basic Explanations and Assumptions:

The dimensions for the seeds are length x width x depth. The location of the hilum is used as the base of the seed, and the length is measured from hilum to the opposite apex. Where a style is present, the length is measured from the hilum to the bottom of the style. Width is measured at a right angle to the length at the widest part. Depth is measured at a right angle to the intersection of height and width lines.

Measurements included are the mean average for each measurement of ten separate seeds.

All measurements in millimeters unless otherwise noted.
