Seed
Abbreviation: ACMI
Seed sample from: 2011
Average Measurement: 1.9 x 0.6 x 0.3
Measurement Range: L: 1.6 - 2.1, W: 0.5 - 1, D: 0.2 - 0.5
Features
Shape: Seed narrowly winged at margins, thicker in the middle. Seed face is narrower at hilum end, broadening at opposite side.
Color: Seed coat papery and white, becoming transparent at the center to reveal a red-brown inner seed.
Surface: Finely longitudinally ridged.
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: obovate 
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.
