Mitotic metaphases and interphase nuclei were analyzed in five ornamental species of Liliales order. Lilium longiflorum (2n = 2x = 24), Hemerocallis flava (2n = 2x = 22) and Hemerocallis fulva var. Kwanso (2n = 3x = 33) are Liliaceae. Crinum crispum (2n = 2x = 22) and Hipeastrum parodii (2n=4x=44) are Amaryllidaceae. The differences observed among the species were: metacentric, submetacentric, subtelocentric and telocentric chromose numbers; number and position of secondary constrictions; chromosome size; total length of chromosomes; maximum number of nucleolus by interphasic nucleus and percentage of fusioned nucleolus.
