In remaining five plants,i.e., Ruta graveolens, Murraya paniculata, andM. Koenigii, Citrus medica var.limomum andAegle marmelos, condition intermediate between and types. conclusion may be said family shows a general trend for attaining placentation from allied taxa like Meliaceae, Rhamnaceae, Vitaceae Zygophyllaceae.
