Seed

Arctostaphylos uva-ursi

Abbreviation: ARUV

Seed sample from: 2009

Average Measurement: 3.9 x 2.3 x 1.8

Measurement Range: L: 3.75 - 4, W: 2.1 - 2.5, D: 1.5 - 2.25

Features

Shape: Fruits segmented with seeds like an orange. Individual seeds are orange segment shaped.

Color: Seeds brown. Hilum is a small brown dot on the ridge where the two flat planes of the segment come together.

Surface: Seed mostly smooth. Rounded surface of seed is ridged. It has a slight sheen on the flat planes.

Latitudinal Cross Section: triangular ARUV lat.png

Longitudinal Cross Section: elliptical ARUV long.png


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.
