Resumen:
Chromosome counts and some karyomorphological observations concerning 14 different orchid species of 9 genera are reported. The results include first counts for: Encyclia argentinensis (Spr.) Hoehne (2n=38), Laelia lundii Rchb. f. et Warm. (2n=40), Campylocentrum neglectum Cogn. (2n=38), Huntleya meleagris Lindl. (2n=46), Oeceoclades maculata (Lindl.) Lindl. (2n=56), Oncidium longicornu Mutel (2n=56) and O. bifolium Sims (2n=108). The chromosome numbers of seven additional species is also confirmed: Eltropectris triloba (Lindl.) Pabst. (2n=46), Pelexia bonariensis (Lindl.) Schltr. (2n=46), Catasetum fimbriatum Rchb. f. (2n=108), Oncidium jonesianum Rchb. f. (2n=30), O. morenoi Dodson et Luer (2n=30), O. pumilum Lindl. (2n=30) and O. longipes Lindl. (2n=56). The results are discussed in relation to previous chromosome studies for each taxa.
