The chromosome numbers of eighteen species of Spiranthinae from Brazil and Mexico and two of Cranichidinae from Ecuador were analysed. Sixteen chromosome records are presented for the first time: Aulosepalum riodelayense (2n = 64), A. tenuiflorum (2n = 60), Cyclopogon luteoalbus (2n = 36), Dichromanthus aurantiacus (2n = 40), Eltroplectris calcarata (2n = 42), Pelexia funckiana (2n = 46), Sarcoglottis assurgens (2n = 46), S. richardiana (2n = 50), S. rosulata (2n = 33), S. sceptrodes (2n = 46), S. schaffneri (2n = 46), S. scintillans (2n = 46), Stenorrhynchos albidomaculatum (2n = 46), S. cf. speciosum (2n = 46), Ponthieva andicola (2n = 26) and P. pilosissima (2n = +/- 42). For Mesadenella cuspidata, a chromosomal number variation (2n = 38/42) was found. In addition, ideograms of five Brazilian species are presented. Chromosome data support phylogenetic relationships suggested by previous cytological and molecular studies. (AU) | |
