Original diagnosis/description

The fossil is a fragment of a fertile leaf approximately 3 cm in width and 7 cm in length. The fragment is at least twice pinnate and the margins entire. Pinnules are deltoid and taper slightly toward the apex of the fragment. The adaxial surface of the rachis is grooved. Sori are oblong and marginal,
attached to a single prominent vein and with an indusium composed partially of laminar tissue. The sori are located exclusively one per pinnule lobe. Sporangia have an oblique, complete annulus composed of approximately 34 cells. Spores are trilete and unornamented and are approximately 30 μm in width.


We name this species after the discoverer of the fossil, William C. Rember, who has worked extensively on the Clarkia Beds since their initial discovery.
