Seed

Agoseris grandiflora

Abbreviation: AGGR

Seed sample from: 2010

Average Measurement: 5.2 x 0.7 x 0.7

Measurement Range: L: 4.6 - 6, W: 0.5 - 0.9, D: 0.5 - 0.9

Features

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.

Latitudinal Cross Section: elliptical Latitudinal AGGR.png

Longitudinal Cross Section: obovate Longitudinal AGGR.png



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.
