B-chromosomes are reported in five species of Crotalaria, namely C. brownei, C. juncea, C. medicaginea, C. retusa and C. sericea. While B-chromosomes were found in root tip cells of all the five species, in pollen mother cells, these were found only in two of these five species, viz. C. brownei and C. retusa. These results have been discussed.
