Seed

Brodiaea coronaria

Abbreviation: BRCO

Seed sample from: 2009

Average Measurement: 1.9 x 1.1 x 1

Measurement Range: L: 1.4 - 2.75, W: 0.75 - 1.8, D: 0.8 - 1.2

Features

Shape: Seed taking a variety of shapes, mostly wide at the hilium and tapering to a point at the opposite end.

Color: Hilium reddish brown to dark brown. Seed black.

Surface: Seed longitudinally grooved very finely, and glossy. Seed body puckered around hilium.

Could be confused with: Camassia quamash or Camassia leichtlinii

Latitudinal Cross Section: elliptical BRCO-lat-cross.png

Longitudinal Cross Section: obovate BRCO-long-cross.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.
