Original protologue

Pinnules small, ovoid to subrectangular, commonly attached by a short, broad stalk; base cordate at both acroscopic and basiscopic sides in the larger pinnules; high in the pinnae of penultimate and ultimate orders, the pinnules become partially attached to the rachis. 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. Midrib prominent in the lower half of larger pinnules and less well marked in the smaller; lateral veins arise from the midvein at a narrow angle to reach the margins nearly perpendicularly and dichotomising up to three times

Etymology
