Abstract Thinopyrum distichum is indigenous to the southern and south western coastal shores of South Africa. Like many of the Thinopyrum species it can be hybridized with wheat. The resulting progeny treated with colchicine produce fertile amphiploids. The need to distinguish the Th. Distichum chromosomes from one another and from those of wheat prompted the investigation of the C-band distribution. The chromosome pairs of Th. distichum were distiguishable from each other and from those of wheat using C-band patterns, morphology and size as identification criteria. The chromosomes ranged from heterobrachial to metacentric with interstitial and telomeric C-bands. The C-band patterns of Th. distichum were similar, but not identical, to those of other Thinopyrum species.
