Seed

Ranunculus occidentalis

Abbreviation: RAOC

Seed sample from: 2011

Average Measurement: 3.5 x 2.6 x 1

Features

Shape: Seed surface is rounded, tapering off to a style that is opposite hilum, but off centered from it.

Additional structures: Style generally 1 – 2 mm long.

Color: Seeds are brown, tending toward a lighter brown or tan at edges of seed surface.

Surface: Seeds are papillose with some small ridges around the surface edges.

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.
