Phyllitis Hill
Terrestrial ferns. Rhizomes short, bearing clathrate scales. Fronds entire or slightly lobed, scaly at least on stipes; veins free. Sori elongated along adjacent veins in pairs; sori of neighbouring veins close, parallel, and appearing at maturity like a single sorus. Indusia elongated, overlying sori, attached to lamina along one edge, those covering a pair of sori opening towards each other. Spores monolete.
8 spp., Europe, N. America, Asia. Naturalised sp. 1.
Phyllitis is closely related to Asplenium and nowadays often merged with it. The undivided fronds (Fig. 1) and paired sori are the most obvious distinguishing features, but the occurrence of intergeneric hybrids indicates the close relationship of the 2 genera and blurs the apparent morphological distinction between them.
