Morphological and molecular variations in the epiphytic CAM fern Pyrrosia piloselloides

Abstract

Variation in shape and size of mature sterile fronds of the epiphytic fern, Pyrrosia piloselloides (L.) Price, was observed. These morphological differences were also linked to genotypic variations of the different fern populations studied. Genetic polymorphism in different populations of P. piloselloides was investigated using random amplified polymorphic DNA markers.
