Abstract

Tectaria brauniana is unusual in its genus by having creeping rhizomes, two-ranked leaves, and free veins. These characters are typical of Triplophyllum and suggest that T. brauniana might belong to that genus instead of Tectaria. To determine the phylogenetic relationships of T. brauniana, we used sequence evidence from four chloroplast DNA markers (rbcL, rps4-trnS, trnG-trnR, and trnL-trnF) to generate a phylogenetic hypothesis for the Tectariaceae. The analysis included the tectarioid genera Arthropteris, Hypoderris, Psammiosorus, Pteridrys, Tectaria, and Triplophyllum. Tectaria brauniana was recovered sister to a clade formed by Hypoderris brownii and Tectaria nicotianifolia, and these three species were sister to Triplophyllum. These two clades were in turn sister to the rest of Tectaria. Thus, to preserve the monophylly of Tectaria, T. brauniana and T. nicotianifolia should be classified in Hypoderris, a genus previously considered monotypic. Accordingly, we make the following new combinations: Hypoderris brauniana and H. nicotianifolia. In this expanded sense, creeping rhizomes, two-ranked leaves, and spiny perispores characterize Hypoderris morphologically. Hypoderris, with its three species, occurs in the Caribbean region, Central America, and the Andes from northern Venezuela to Bolivia
