Measurement Range: L: 1.3 - 1.75, W: 0.6 - 1, D: 0.1 - 0.3

Features

Shape: Seeds flat, somewhat winged, especially at hilum end and opposite. Accumbent cotyledons and sulcus present.

Color: Seed dark brown in center, darkening to black at the winged edges. Hilum inconspicuous.

Surface: Texture is bumpy, and seed is somewhat lustrous.

Latitudinal Cross Section: elliptical

Longitudinal Cross Section: elliptical

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.
