 Aim and Background . Heliotropium chorassanicum is an endemic species to Iran which has not been carefully investigated . It is widespread in Kopetdagh area in Khorasan province . In this study anatomical & cytological structure of root , shoot , leaf , flower and its meristem and fruit of above mentioned species has been investigated .

Materials and Methods . The samples was collected from Kharasan - e Razavi province and after fixation by FAA fixator , stained by methylgreen & karmen hematoxyline . To understand its structure , pictures have been taken by light microscope .

Results . The results show that leaf blade has epiderm with frequent trichomes cuticule very narrow and thin mesophyll with chlorophyll , isobillateral in both surfaces , bundle sheath is lanceolate and phloem with 2-6 cell layer stomata mostly concentrated at hypoderm .

Conclusions . With pay attention to identification key and comparition of leaves and trichomes in this species it is conclude that the trichomes are simple with cupshape end and clear cell base . The root has secondary growth .
