Chromosomes of Some Species of Agapanthus

Abstract

Chromosomes were studied from five species and two unnamed plants of the genus Agapanthus. Karyotypes and ideograms were prepared, the chromosomes were grouped into classes of different size, and formulae were prepared for all the plants. The 2n number was found to be 32 in A. praecox and A. orientalis, 30 in A. campanulata, A. inapertus, A. minimus, and one of the unnamed plants, and 29 in the other unnamed plant. A. orientalis and one of the unnamed plants had two supernumerary chromosomes. The chromosomes of A. praecox and A. orientalis are not inconsistent with the position that these species are synonyms.
