Alsophila × boytelii

Alsophila × boytelii is a tree fern endemic to the Sierra Maestra range of southeastern Cuba. It is a natural interspecific hybrid between Alsophila balanocarpa and Alsophila woodwardioides. The spores of A. × boytelii are normal in appearance; Caluff and Serrano (2002) suggest that it might therefore be fertile. This theory is strengthened by the presence of a large population of A. × boytelii in the Gran Piedra area. Caluff and Serrano (2002) note that "a full range of intermediates linking this hybrid with its parent species suggests the occurrence of backcrossing".[2]
