TL;DR: Karyotype analyses were made using root tip mitosis in 21 species of South Indian Apiaceae as mentioned in this paper, and the first record of chromosome numbers have been made in Hydro-cotyle conferta (2n=18), H. candolleana (2 n=18).

TL;DR: Karyotypes in the family show differences in absolute chromosome size indicating changes in nuclear DNA in evolution, and the number 8 is suggested as the ancestral basic number of the family.

TL;DR: Fifteen species of Ranunculaceae under eight genera have been studied, mostly collected from different regions of Ooty and Kodaikanal of Western Ghats, and a wide range of chromosome numbers, chromosome sizes and total chromosome lengths of various species studied is shown.

TL;DR: Karyotypes in the Scrophulariaceae family show differences in absolute chromosome size indicating changes in nuclear DNA in evolution, and the meiotic chromosome number studied in 17 species is in confirmation with the mitotic chromosomes.

TL;DR: Karyotypes in the family show differences in absolute chromosome size indicating changes in nuclear DNA in evolution, and the primary basic number of the family may be n=8 and from this other basic numbers should have originated by means of aneuploidy and euploidsy.
