Karyotype analysis of a new cytotype of Callisia fragrans (Lindl.) Woodson (Commelinaceae)

Callisia is a tortuous genus reported to show a wide range of chromosome counts. Present paper reports an unusual chromosome number 2n = 18 for C. fragrans, a number that is so far not known, not only in C. fragrans but also for the entire genus Callisia. The variable chromosome number and varied karyotype architecture is indicative of the fact that the genome of the genus Callisia may be still unstable and in constant evolution.
