Abstract

Chromosome counts from natural populations of Abrus pulchellus in Nigeria were carried out. 
Tetraploid (2n = 44) chromosome number was constant in all the samples investigated. The 44 
chromosomes fall into three cytomorphological categories: eight metacentric and eight sub
metacentric pairs, and six acrocentric pairs. The chromosomes are relatively small in length ranging 
from 0.5 to 1.4 m. The polyploid (tetraploid) cytotype is reported for the first time for this taxon.
