Seed
Abbreviation: ACMI
Seed sample from: 2011
Measurement: 1.9 x 0.6 x 0.3
Features: Seed narrowly winged at margins, thicker in the middle. Seed face is narrower at hilium end, broadening at opposite side Seed coat papery and white, becoming transparent at the center to reveal a red-brown inner seed.
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.
