Abstract

This paper describes and illustrates a new hybrid, Jamesonia 3intermedia, from Serra dos Órgãos, Rio de Janeiro State, Brazil. The hybrid, most of whose spores are aborted, shows intermediate morphology between its putative parents (J. biardii and J. insignis) in lamina dissection, shape of the ultimate segments, and pubescence of the adaxial surface of the pinnae and rachises.
