Abstract

A new cupule generically comparable to Calathospermum scoticum Walton is described containing ovules identical in form to the seeds known as Salpingostoma dasu Gordon. The specimens of this new species illustrate some interesting morphological features new to the genus. The cupule is believed to be equivalent to a large part of a frond and its branching may be interpreted as a pinnate system.
