Seed
Abbreviation: ARHI
Seed sample from: 2011
Measurement: 1.6 x 0.9 x 0.2
Features: Seeds flat, somewhat winged, especially at hilium end and opposite. Accumbent cotyledons and sulcus present. Seed dark brown in center, darkening to black at the winged edges. Hilium inconspicuous.
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.
