Pseudoctenis is a genus of fossil foliage attributable to the Cycadales. It is one of the most common genera of cycad fossil foliage in the Mesozoic.

Taxonomy[]

The genus was erected by Albert Seward based on material from the Jurassic of Sutherland. Although he did not publish a diagnosis for the genus, he noticed the similarity with the genus Ctenis, stating that the main difference between the two is the absence of anastomoses in Pseudoctenis.
