Seed sample from: 2010
Average Measurement: 5.2 x 0.7 x 0.7
Shape: Seeds tapering to a beak 2-3 times as long as the body of the seed.
Color: Seeds pale brown with white, glossy hilum.
Additional Structures: Pappus white, and downy.
Surface: Seed body deeply longitudinally grooved. Ridges are finely toothed. Seed slightly glossy.
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.
