Background and Aims:

In Mexico four hybrids in Pleopeltis are known so far. The presence of these natural hybrids of Polypodiaceae is part of the speciation processes and contributes to the higher taxonomic diversity in this country. In this paper we disclose two new hybrids collected in the Sierra Madre Oriental in Puebla, Mexico, whereas another hybrid is formally recognized.

Methods:

These new hybrids are defined by a comparative study of morphological characters in laminar architecture and indument type.

Key results:

We describe two new hybrids: Pleopeltis ×gracilis and P. ×pueblensis and validly publish P. ×arreguiniae.

Conclusions:

With these nothotaxa, Mexico has now seven hybrids of Pleopeltis. Additionally, to support correct identification, we present comparative tables and a key.
