Popis:	Chromosome numbers for eight genera of Costa Rican ferns are reported here for the first time. These are: Neurocallis, n = 58; Marginariopsis, n = 35; Dicranoglossum, n = 36; Glyphotaenium, n = 37; Cochlidium, n = 33; Ormoloma, n = 42; Peltapteris, n = 40; and Loxsomopsis, n = 46. Chromosome observations involving several other genera are included: Solanopteris, n = 37; Xiphopteris, n = 32; Hemidictyum, n = 31; Pleuroderris, 2n = 80; Dictyoxiphium, 2n = 80; and Polystichum, n = 41. These numbers are compared to those of genera of presumed taxonomic affinity.
