Type

Original diagnosis/description

At least tripinnate fronds, with subperpendicularly inserted pinnae characterised by intercalary pinnules on penultimate rachises and imparinnate last order pinnae. Pinnules small, ovoid to subrectangular, commonly attached by a short, broad stalk. First anadromous and catadromous pinnules of last order pinnae of more reduced size, allowing space for intercalary pinnules on the penultimate rachis; anadromous pinnules orbicular; catadromous ovoid and similar to the standard laterals, but shorter, with half their length.

Etymology

Named after Robert H. Wagner, in recognition of his contribution to Carboniferous palaeobotany and stratigraphy, and Spanish Carboniferous geology in particular.
