Meiotic chromosome behavior in four intergeneric hybrids of Neofinetia falcata Hu was investigated. N. falcata×Vanda lamellata Ldl., N. falcata×Ascocentrum miniatum Schltr., and N. falcata×Ascocentrum ampullaceum Schltr. showed 19-17 bivalent chromosomes with means of about 18.6 at metaphase I, indicating a strong homology of the parental genomes, whereas N. falcata×Aerides jarckianum Schltr. exhibited 10-2 bivalents with a mean of 6.1, indicating a relatively poor homology of the parental genomes. On the basis of chromosomal affinity, Neofinetia is very closely related to Ascocentrum and strap-leaved Vanda and more distantly related to Aerides.
