Seed
Abbreviation: ARHI
Seed sample from: 2011
Average Measurement: 1.6 x 0.9 x 0.2
Features
Shape: Seeds flat, somewhat winged, especially at hilum end and opposite. Accumbent cotyledons and sulcus present.
Color: Seed dark brown in center, darkening to black at the winged edges. Hilum inconspicuous.
Surface: Texture is bumpy, and seed is somewhat lustrous.
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: elliptical 
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.
