Seed

Abbreviation: ARMA

Seed sample from: 2011

Average Measurement: 4.9 x 1.2 x 1.2

Measurement Range: L: 4.3 – 5.5, W: 1 – 1.5, D: 1.1 – 1.4

Features

Shape: Seeds narrow at hilum, widening at opposite apex to form a tube shaped opening with five ribs flaring out from the end of the seed. Inside tube structure is five lobed star shaped structure.

Color: Ribs brown, connected with a white transparent membrane. Star shaped structure is tan.

Surface: Seed is longitudinally ribbed, and has a slight sheen.

Latitudinal Cross Section: elliptical ARMA lat.png

Longitudinal Cross Section: obovate ARMA long.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.
