Seed
Abbreviation: ARUV
Seed sample from: 2009
Measurement: 3.9 x 2.3 x 1.8
Features: Fruits segmented with seeds like an orange. Individual seeds are orange segment shaped. Hilium is a small brown dot on the ridge where the two planes of the segment come together. Seeds brown.
Seed mostly smooth. Rounded surface of seed is ridged. It has a slight sheen on the flat planes.
Latitudinal Cross Section: triangular
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.
