1) The karyotype analysis is carried out on nine species, one subspecies of
Cacalia and
Syneilesis.
2) There can be found that
Syneilesis palmata (or
Cacalia krameri) is karyologically different from the member of
Cacalia (Bucacalia) and shows to have a specific constitution of the karyotype.
3) All the members of the genus
Cacalia studied are classified into four types from the view point of the karyotype and Sect. Bucacalia is subdivided into three different subtypes.
4) Most of the genus
Cacalia studied have, in general, characteristic asymmetrical karyotypes which are derived from the higher polyploidization of a basic number of ten (or five).
5) A close phylogenic relationship between
C. hastata ssp.
farfaraefolia and
C. hastata ssp.
orientalis is suggested.
6) The relation between the genus
Cacalia and the genus
Syneilesis is discussed from the karyological stand point.
