Title

Subject
Starch grains viewed under 400x
Description
Shape: Lenticular - Circular/sub-circular in plan view, biconvex in side view.
Surface: smooth, sometimes with very faint dimples. Surface facets may be present, or a slight indentation at the hilum.
Outer wall: single
Hilum: centric & closed
Extinction cross: "very distinct and usually bilaterally symmetrical" (Henry et al. 2009: Table 2)
Lamellae: few lamellae visible, particularly with the larger grains.
Fissures: none
Plant part: grain
Notes: multiple beta granules (transitory starch - small grains) present. Bere granules appear potentially smaller on average than conventional Hordeum vulgare range (~20 microns).
