Seed
Abbreviation: ANMA
Seed sample from 2010
Average Measurement: 0.6 x 0.2 x 0.2
Measurement Range: L: 0.4 - 0.75, W: 0.1 - 0.3, D: 0.1 - 0.3
Features
Shape: Seeds somewhat ribbed. Right above hilum, seed narrows considerably before flaring out again.
Color: Seed is brown. Hilum is glossy and puckered, lighter colored that rest of seed.
Additional Features: Pappus of downy white hairs significantly longer that seed itself.
Surface: Seed covered in clear globules and is slightly lustrous.
Could be confused with: Antennaria howellii
Latitudinal Cross Section: elliptical 
Longitudinal Cross Section: elliptical 
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.
