Convolvulus pluricaulis Chois. is a prostrate, spreading, perennial, wild herb commonly found on sandy or rocky ground under xerophytic conditions in northern India. The species is marked by great morphological variability especially in size of the flower. Our cytological studies indicated the existence of intraspecific polyploidy in the species. The present investigation was, therefore, undertaken to study the possible relationship between cytological and morphological forms of the species.
