Although a number of varieties have been recorded, most of these are of rather indefinite or erratic character, the best being— Imbricatum (Fig. 34), in which the fronds are congested, and the pinnae over- lapping. Plumosum.—A very beautiful, robust, bipinnate form, barren and rare. Ramosum.—A very marked variety, with branching fronds, found in Dorsetshire by Mr. G. B.
