Distribution of Parthenium hysterophorus in the Peshawar Valley in Pakistan
Parthenium hysterophorus (Asteraceae, EPPO Alert List) is considered to have been introduced into Pakistan in the 1980s from India. The species has recently been reported in Islamabad, and is becoming a weed in the Peshawar Valley, in the Khyber Pakhtunkhwa and Punjab provinces of Pakistan. The species is spreading rapidly along roadsides, into agricultural fields and in wastelands.
