Seed

Seed sample from: 2010

'Average measurement: 0.7 x 1.5 x 1

Measurement range: L: 0.5 - 0.9, W: 1 -1.6, D: 0.7 – 1.1

Features

Color: Seed bright red with a large, white, elliptical shaped depression on the longer face of the seed that is the hilium.

Syrface: Seeds matte and bumpy, with some wrinkling around the hilium depression.

Could be confused with: Collinsia parviflora.

Latitudinal cross section: elliptical COGR lat.png

Longitudinal cross section: irregular

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.
