Johannesburg, in fulfilment of the requirements for the degree of Master of ScienceThere are a number of recorded difficulties in classing lithop species according to their

of sequence similarity between any two genomic DNA's, is the method of choice for establishing
phylogenetic relationships between species. (Abbreviation abstract}Andrew Chakane 201
