Abstract :
The study of morphology and anatomy of seven most common weed species infesting agricultural and non-agricultural lands of rainfed area of Bannu region were investigated during 2012. The study included Datura metel L., Euphorbia hirta L., Fagonia cretica L., Heliotropium europaeum L., Parthenium hysterophorus L., Solanum surattense Burm f. and Withania somnifera (L.) Dunal. It was found that most of the investigated species had well developed vascular bundles both in root and stem systems which clarified their adaptation in the severe rain-fed conditions of Bannu, Khyber Pakhtunkhwa Pakistan. Due to the special morphological and anatomical features, the capacity of rapid absorption of water along with minerals from the soil may be facilitated to compensate the rapid water loss, and thus can also be regarded as common xerophytes. So far as the interaction of these species is concerned within the prevailing environment of Bannu region, their morphological, anatomical and histological characteristics are suitable for their successful growth in rain-fed condition of the region.
