QillaSaifullah Tehsil.

native to the warm temperate and tropical regions (Ashokkumar et al., 2013). It is found as a weed in cultivated
fields and moist and marshy grounds in QillaSaifullahTehsil (our research area).
Echinochloa colona
(Poaceae): It is considered to be one of the finest fodder grasses and is eagerly eaten by cattle
both before and after flowering (Cope, 1982). It frequently occurs in wet places and rice fields in Pakistan
(Marwatet al., 2013) and is also found in QillaSaifullahTehsil.

Baltistan and Kashmir areas of Pakistan (Ghazanfar, 1977). In our research area i.e., QillaSaifullah Tehsil it is also
found (Figure 5).
Mentha longifolia
(Lamiaceae) is a polymorphic aromatic (Hedge, 1990) and semi-aquatic herb (Ishaqet et al.,
2017). The correct nomenclatural citation of this species is, to some extent, a matter of opinion. In this paper

M. longifolia
has been favoured. In QillaSaifullah Tehsil, it is also found.
Nasturtium officinale

Paspalum paspaloides
(Michx.) Scribner (Poaceae) occurs as a weed in garden, along ditches and irrigation
channels, in rice-fields and in marshy places (Cope, 1982). It also grows in our research area i.e., QillaSaifullah
Tehsil.

(Poaceae) is one of the 2 native species of Pakistan (Cope, 1982). In QillaSaifullah Tehsil it is
found as a weed in cultivated grounds and moistplaces.
