Tectariaceae

Tectaria rivalis

The Tectariaceae are a family of genuine ferns ( Polypodiopsida ).

Features

The rhizomes are usually short creeping or ascending. They have a Dictyostele and wear scales. The petiole is not falling down, and in cross -section, a ring of vascular bundles. The leaf blades are easy, simple or bipinnate. Axles and leaf nerves, sometimes called the spreading are hairy. The nerve end freely or abundantly anastomosing. The indusia are kidney-shaped or plate -like, in some ways also missing. The spores are brown, kidney-shaped, monolet (one scar ) and ornamented different.

The basic chromosome number is x = 40, rarely 39 or 41

Dissemination

The family is pantropical spreading and growing terrestrial.

System

The family is in the specified scope here probably monophyletic. It comprises 8 to 15 genera with about 230 species, most of them in Tectaria sl The genus boundaries are unclear.

The classes are according to Smith et al. 2006:

• Aenigmopteris Holttum, with about two to four species in Malaysia's
• Arthropteris J. Sm, with about 8-20 species that occur from tropical Africa and Asia to New Zealand
• Heterogonium C. Presl, with about 14-20 species in Mauritius, South East Asia and Malaysia's
• Hypoderris R. Br ex Hook, with probably only a kind of tropical America. : Hypoderris brownii J. Sm

• Psammiosorus paucivenius (C. AD) C. Chr
