The mitotic metaphases of five Andean species of genus are described for the first time. The evolutionary and interspecific genetic relationships within three Neotropical species groups are analyzed. The diploid chromosome number for each species is as follows: Céspedes et Rafael, 2012 2n = 6 (2V, 1J) (X = J, Y = R), Vela et Rafael, 2004 2n = 10 (3R, 2V) (X = V, Y = R), Vela et Rafael, 2005 2n = 10 (3R, 1V, 1D) (X = V, Y = R), Vela et Rafael, 2005 2n = 12 (4R, 2V) (X = V, Y = R), Llangarí-Arizo et Rafael, 2018 2n = 8 (3R, 1J) (X = J, Y = R).
首次描述了该属五个安第斯物种的有丝分裂中期。分析了三个新热带物种组内的进化和种间遗传关系。每个物种的二倍体染色体数如下:塞斯佩德斯和拉斐尔,2012年 2n = 6(2V,1J)(X = J,Y = R),贝拉和拉斐尔,2004年 2n = 10(3R,2V)(X = V,Y = R),贝拉和拉斐尔,2005年 2n = 10(3R,1V,1D)(X = V,Y = R),贝拉和拉斐尔,2005年 2n = 12(4R,2V)(X = V,Y = R),兰加里 - 阿里佐和拉斐尔,2018年 2n = 8(3R,1J)(X = J,Y = R)。
