AI Article Synopsis
- The fern genus Aenigmopteris has faced ongoing debate regarding its phylogenetic relationships, lacking prior molecular data.
- Through analysis of three chloroplast DNA regions, researchers found that Aenigmopteris dubia and A. elegans are closely related to and embedded within the Tectaria group.
- As a result of the findings, all five species of Aenigmopteris are reclassified into the Tectaria genus, as their morphological features fit within Tectaria's variation range.
Article Abstract
The phylogenetic affinities of the fern genus Aenigmopteris have been the subject of considerable disagreement, but until now, no molecular data were available from the genus. Based on the analysis of three chloroplast DNA regions (rbcL, rps16-matK, and trnL-F) we demonstrate that Aenigmopteris dubia (the type species of the genus) and A. elegans are closely related and deeply imbedded in Tectaria. The other three species of genus are morphologically very similar; we therefore transfer all five known species into Tectaria. Detailed morphological comparison further shows that previously proposed diagnostic characters of Aenigmopteris fall within the range of variation of a broadly circumscribed Tectaria.
