Abstract
In the present study an account is given of an investigation based on the results of the Taxonomic research work conducted in Dera Ismail Khan (D.I. Khan) District, Khyber Pakhtunkhwa (KPK), Pakistan, during 2005-2007. The area was surveyed and collection of semi-aquatic and marshland angiosperms was made at least 2 times from 15 sites of various aquatic habitats. The collected materials were identified with the help of available literature and by comparing with voucher specimens at the herbarium of the Department of Plant Sciences, Quaid-i-Azam University, Islamabad (ISL). In total 40 semi aquatic plant species belonging to 26 genera of 15 families were identified. Cyperaceae was the largest family that contributed 16 species (40%), followed by Poaceae with 6 species (15%), Polygonaceae 4 species (10 %), Ranunculaceae and Typhaceae with 2 species (5% each); while 10 families contributed 1 species (2.5% each). Data inventory consists of botanical name, family, class, flowering period, availability, distribution and diagnostic characters. Detailed account of the semi aquatic and marshland angiosperms of Dera Ismail Khan is not available. Therefore, the present study is an attempt to highlight such angiospermic plant species.
