Measurement detail of root, stem and bract anatomical characteristics of Cyperus laevigatus. a. Haroonabad Root TS: Vascular region much reduced, cortical region comprising large regularly arranged aerenchyma. Outer cortex 3–4 layered thick. b. Haroonabad Stem TS: Average sized vascular bundles, large aerenchyma, densely packed chlorenchyma inside epidermis. c. Smaller vascular region with 6 narrow vessels, larger aerenchyma, outer cotex 4–6 layered thick, inner cortex much reduced. d. Khushab Stem TS: Small vascular bundles, average sized aerenchyma, higher sclerification inside epidermis. e. Jhalar lake Root TS: Vascular region with four broader vessels, average sized aerenchyma, cells of outer and inner cortex regularly arranged. f. Jhalar lake Stem TS: Smaller vascular bundles, regularly arranged aerenchyma and cortical cells, reduced chlorenchyma. g. Pakka anna Root TS: Vascular region with 3 broader and one narrow vessel, rare aerenchyma, smaller cortical cells. h. Pakka anna Stem TS: Larger vascular bundles, reduced aerenchyma, regularly arranged cortical cells, dense chlorenchyma. i. Kalar Kahar lake Root TS: Vascular region with 4 broadest vessels, very large aerenchyma, small sized cortical cells. j. Kalar Kahar lake Stem TS: Larger vascular bundles, irregular aerenchyma, chlorenchyma arranged inner side of epidermis sparsely. k. Sahianwala Root TS: Vascular region with 3 broader and one narrow vessel, smaller sized cortical cells near vascular region that become larger in mid and small cells inside epidermis. l. Sahianwala Stem TS: Medium to large vascular bundles, very large aerenchyma.
