Weed Flora

The present study explains floristic composition and ecological attributes characteristics of weeds of maize crop in district Swabi during September-October, 2018. A total of 28 weeds species distributed in 27 genera and 15 families were reported from the selected maize fields of the study area. Out of 15 families, 12 were dicots having (17 genera and 18 species) and 3 were monocots having (10 genera and 10 species). Poaceae was dominant family contributed 8 species. Amaranthaceae (5 spp.) followed by Aizoaceae and Convolvulaceae (2 spp.) each. The rest of 11 families were represented by single species each. Annuals contributed 19 (67.8%) species while perennials shared 9 (32.2%) species. Life-form spectra indicated that therophytes were dominant and abundant life form with 17 (60.7%) species. Leaf size spectra revealed that microphylls were major leaf size class with 12 (42.8 %) species. There were 25 (89.3%) species with simple leaves, 2 (7.1 %) species with compound leaves while 1 (3.6 %) species was represented by dissected leaves.

Field surveys were carried out to evaluate the floristic diversity and biological spectrum of Lower Tanawal, District Abbottabad in different seasons during 2016-2018. This study area was divided into 80 stands on the basis of physiognomy of the vegetation. Life form classes and leaf spectra were classified following Raunkiers methodology. In total, 286 plant species belonging to 86 families were recorded, out of which herbaceous growth form dominated the study area with 187 species, followed by shrub with 54 species. Among all 86 families, Asteraceae was found to be the most dominant family with 25 species, followed by Fabaceae with 24 species and Rosaceae with 20 species. Based on life form classes, Therophytic life form was the leading class with 113 species (39.5104%), followed by Nanophanerophytes with 45 species (15.7342%). In leaf size spectra, Microphylls dominated the flora with 88 species (30.7692%), followed by Mesophyll with 81 species (28.3216%). This study shows the complete floristic composition that may be important as reference work for future ethnobotanical, ecological and conservational studies.

Field surveys were carried out to assess the phytodiversity, phenology, leaf size, leaf shape, life form and ethnobotany of weed flora of village Sufaid Sung, Peshawar from March 2017 to June 2019. Overall, 95 species have been reported associated with 31 families. Dominant families were Poaceae (22 species), Asteraceae (10 species) followed by Amaranthaceae and Papilionaceae (6 species each), Brassicaceae and Polygonaceae (5 species each), Euphorbiaceae and Solanaceae (4 species), Apiaceae, Caryophyllaceae, Cyperaceae, Malvaceae and Verbenaceae added 2 species, Chenopodiaceae and Convolvulaceae contributed 3 species, Apiaceae, Caryophyllaceae, Cyperaceae, Malvaceae and Verbenaceae added 2 species while the rest of 16 families contributed a single species each. The dominant life form was therophytes (76 species) followed by hemicryptophytes (11 species) and geophytes (8 species). Leaf size of the flora showed that the most dominant leaf size class was mesophyll (38 species) followed by macrophyll and microphyll (18 species each), nanopohyll (15 species) and leptophyll (5 species) while a single aphyllous. Simple leaf species were 68 while 26 species had dissected leaves. This study shows a detailed phytodiversical situation of weeds that may be important as reference work for future ethnobotanical, ecological, weed management and conservational studies.

Biological Spectrum

The plant species of Hazarnoe Forest of District Malakand, Khyber Pakhtunkhwa, were evaluated floristically from April 2016 to November 2017. Of the total 240 reported plant species, 38 were monocots, 196 dicots which belongs to 85 families and 188 genera respectively. Poaceae was the leading family contributed 20 species. Family Asteraceae contributed (14 spp.), Lamiaceae (13 spp.) while Papilionaceae and Solanaceae each with 10 species. Of the total plant taxa perennials were 161 species compared to annuals (73 spp.) and biennials (06 spp.). The dominant growth form was herbs that contributed (108 spp.) followed by trees (50spp.) and shrubs (45 spp.) respectively. Phanerophytes were the dominant life-form (92 spp.) whereas leaf size spectrum of microphyll was reported as abundant in the overall floristic. Phanerophytes and microphyll leaf size was the dominant life forms which show typical climate of subtropical region governing the area. Conclusion of study was that the vegetation of the area is under heavy biotic pressure and need proper conservation.

Ethnobotanical Uses

The present study was carried out to enlist the grass flora of Kalash valley, Pakistan theirecological characteristics and ethnobotanical uses. A total of 36 grass species belonging to 29 genera wereidentified. Poa was the dominant genus with 4 (11.11%) species followed by Avena, Bromus, Hordeumand Lolium represented by 2 (5.55%) species each. The remaining genera had one species each. Ecologicalcharacteristics revealed that 23 (63.89%) species were rarely occurring, 9 (25%) were common and 4(11.11%) species were abundantly occurring in the valley. Life form spectra showed that therophytes weredominant with 24 (66.67%) species followed by hemicryptophytes with 8 (22.22%) species, chamaephytes3 (8.33%) and geophytes had one (2.78%) species. Leaf size spectra revealed that 26 (72.22%) specieswere nanophylls, 4 (11.11%) were microphylls and 3 (8.33%) were mesophylls. 27 (75%) species weregrowing on dry places and 9 (25%) were growing on wet soils. Similarly, 33 (91.67%) were fodder species,3 (11.11%) were food species and 2 (5.55%) species were used for thatching purposes in the valley. Thepresent information will be useful for further ecological and biological researches on the grasses in thisdry temperate region of Pakistan.
