Morphology and Anatomy of the Fern Genus Gymnogrammitis

Received: 13 April 1970   

The anatomy and morphology of Gymnogrammitis Griffith, the generic affinity of which has been in dispute, is described in detail for the first time. The diagnostic features are that the stem is protected by peltate scales with both marginal and superficial hairs. Its ground tissue is parenchymatous and is provided with numerous pits on the cell-walls. Scattered among the parenchyma are a large number of groups of tanniniferous cells. The vascular cylinder is dorsiventral and is dissected into many small subequal meristeles. The articulation pad, separating the petiole from the rhizome is homogeneous and is composed of thin-walled parenchymatous cells. Two large adaxial and two or more smaller abaxial bundles supply the petiole. The receptacles are seated on the vein and are without any indusia. Spores are bilateral and have no perine; the ektexine is thick and bears many clava- or bacula-like projections. It is argued that the genus is a well-defined taxon and that it shows affinities with the Davallioid ferns.
