Acmopyle glabra
Taxonomy
Acmopyle glabra was named by Hill and Carpenter (1991) [Type locality: Regatta Point, Tasmania.
Specimens examined: RPE-006, C-222.]. It is considered to be a form taxon. Its type specimen is RPE-006, housed in the Department of Plant Science, University of Tasmania., a sterile axis (Cuticle), and it is a compression fossil. Its type locality is Regatta Point Eocene, which is in an Eocene fluvial-deltaic mudstone/sandstone in Australia.

Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| R. S. Hill and R. J. Carpenter 1991 | Leaves distichous, bilaterally flattened, falcate, decurrent, strongly keeled with a single vein. Leaf length:width ratio 6:1-8:1. Short shoot up to 4 cm long, 1.6 cm wide. Leaf irregularly amphistomatic. On one leaf surface stomates in two orderly bands running from leaf base to apex, cuticle relatively thin. On the other surface stomates in two discontinuous bands, interrupted by many hypoplastic stomates, cuticle relatively thick. Cuticle on all subsidiary cells granular. Flange between guard and subsidiary cells well developed, smooth, relatively entire-margined. Polar extensions well developed, wide, continuous with flange between guard and subsidiary cells. Flange between guard cells well developed, with thin polar extensions. Leaf glabrous. |
