In present study we have made an attempt to trace possible lines in the evolution of A. bonaccordensis separating from A. hohenackeri, where translocations at the chromosomal level could have resulted in a shift of the habitat during evolution of A. bonaccordensis. This species is occurring as an endemic taxon at a higher altitude than it may have been the case with its ancestor that occupied lower altitudes and possibly a broader ecological niche. Morphological and physiological differences between the recent two closely related taxa, in spadix and appendix characters, corm flesh colour, pollen morphology and oxalate content, may be A new translocation between chromosomes 6 and 9 helps to establish diagnosis of renal oncocytoma
