Abstract

× Cyclobotrya telespirensis, a new hybrid and new hybrid fern genus, is described from the margin of the Teles Pires River in southern Brazilian Amazon. The new nothotaxon is derived from the cross between Polybotrya goyazensis and Cyclodium meniscioides var. meniscioides. This is the first report of hybridization between Cyclodium and Polybotrya. It represents a rare instance of an intergeneric hybrid in ferns. We present illustrations, a description, and taxonomic and ecologic comments of the new nothotaxon.

Resumo

× Cyclobotrya telespirensis, um novo híbrido e novo gênero híbrido são descritos, originário das margens do rio Teles Pires, no sudeste da Amazônia brasileira. O novo nototáxon é derivado do cruzamento entre Polybotrya goyazensis e Cyclodium meniscioides var. meniscioides. Este é o primeiro registro de hibridização entre os gêneros Cyclodium e Polybotrya e um raro caso de hibridização intergenérica em samambaias. São apresentados ilustrações, descrição e comentários taxonômicos e ecológicos a respeito do novo nototáxon.
