13 December 2002 Cuban novelties in the genus Alsophila (Cyatheaceae)

Three new interspecific hybrids of Alsophila have been detected in Cuba: A. ×boytelii in the Sierra Maestra range, E Cuba; A. ×medinae in the Trinidad Mountains, Central Cuba; and A. ×fagildei in the Guantánamo province, E Cuba. They have spores of normal appearance and might therefore well be fertile, as suggested by the presence, in the Gran Piedra area, of a large population of A. ×boytelii; a full range of intermediates linking this hybrid with its parent species suggests the occurrence of backcrossing.
