This present study covered 8 species (7genera) belonging to the subfamily Maloideae (Rosaceae). These plant samples were collected from 5 different Egyptian sites. The study includes morphological and anatomical studies for all the plant organs both vegetative or reproductive. The 68 recorded characters put in data matrix and these results were analyzed numerically using the (MVSP) program to determine the similarity between these studied species. The program classified the studied plant samples into two clusters, the first cluster includes 3 species (No.1-3), the highest similarity was 72.956 between Cydonia sp. and Crataegus sp., while the lowest similarity was 64.052 between Cydonia sp. and Cotoneaster sp. The second cluster includes the remainder 5 species; from (No. 4 to 8), The highest similarity was 73.054 between species Pyrus calleryana and P. communis, while the lowest similarity was 59.740 between Rhiphiolepis sp. and the other 4 samples in the same cluster (Eriobotrya sp., Malus sp., Pyrus calleryana and P. communis.). Also, the results used in the constructing of an indented key to identified and to easily the distinguish the eight studied samples.
