Seed sample from: 2011
Average Measurement: 2.8 x 1.8 x 1.8
Shape: Narrow at hilum end, broadening out to a more rounded opposite end. CAQU slightly smaller than CALEI.
Color: Seeds black. Hilum more conspicuously contrasting seed color in CALEI than CAQU.
Surface: Seeds frequently pitted, glossy, and heavily wrinkled. CAQU tends to be more lustrous than CALEI. Seeds have a ridge that runs from hilum to opposite end.
Could be confused with: Camassia leichtlinii or Brodiaea coronaria
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.
