Seed sample from: 2011
Average measurement: 0.7 x 1.5 x 1
Measurement range: L: 0.5 - 0.9, W: 1.3 x 1.7, D: 0.9 x 1.3
Color Seeds bright red with elliptical, white, large depression that is the hilium on a longer seed side.
Surface Seeds red, matte, and very slightly bumpy. Possibly smoother than COGR. Some seeds have seed coat ridges at the edge of the seed, giving it a somewhat winged look.
Seed slightly larger than Collinsia grandiflora.
Could be confused with: Collinsia grandiflora.
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.
