Palomino, G.; Quero, H.J.
Cytologia 57(4): 485-489
Studies of S. yapa, S. mexicana and S. gretheriae revealed that all 3 species have chromosome counts of 2n = 36. The karyotypes of S. yapa and S. mexicana were similar, with metacentrics and submetacentrics and 4 pairs of chromosomes with satellites. S. gretheriae had 9 pairs of satellited chromosomes and a pair of heteromorphic chromosomes which were almost 3 times larger than the average of other chromosomes in its complement.
