A karyomorphological study on Selenipedium aequinoctiale Garay, Orchidaceae
Karyomorphological observation was carried out in Selenipedium aequinoctiale, and the chromosome number of 2n=20 was reported here for the first time in the genus.
The karyomorphological characteristics of this species, i.e. karyotype
of resting chromosome, length of metaphase chromosomes and position of
the secondary constriction, were clearly different from other three genera
in subfamily Cypripedioideae.
