Prunella vulgaris

Abbreviation: PRVU

Seed sample from: 2010

Average Measurement: 2.1 x 1.6 x 1.1

Measurement Range: L: 1.8 - 2.3, W: 1.3 - 1.9, D: 0.75 - 1.2


Shape: Seeds narrow at hilum end and broadening at opposite apex. Hilum protruding in a “v” or “u” shape.

Color: Seeds dark brown with black ribbing. Hilum white.

Surface: Seeds longitudinally striated with darker lines. Entire seed is very glossy, especially hilum.

Latitudinal Cross Section: elliptical PRVU lat elliptical.png

Longitudinal Cross Section: elliptical PRVU long elliptical.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.
