Seed
_use.jpg)
Abbreviation: ANHO
Seed sample from: 2009
Average Measurement: 1.1 x 0.3 x 0.2
Measurement Range: L: 0.9 - 1.5, W: 0.2 - 0.4, D: 0.1 - 0.3
Features
Shape: Slightly larger than Anaphalis margaritacea and has lighter, glossier, and more dimpled hilum.
Color: Brown.
Additional Structures: At opposite end of hilum is pappus of white hairs that attach in a ring around the end of the seed. Pappus is significantly longer that seed.
Surface: Seed is slightly grooved, hairy, and covered with white globules.
Could be confused with: Anaphalis margaritacea
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.
