  The study was confined to the 3 medicinally important species of the genus Artemisia Linn. The morphological features, such as, plant size, leaf-shape and size, petiole length, the inflorescence type and the details of capitulum, i.e., the disc and ray florets were studied from the herbarium specimens preserved in the Quaid-I-Azam University Herbarium. Many properties and the uses of these species were determined. The studies on morphological characters revealed that the characters like, heads either homogamous or heterogamous and the receptacle either glabrous or hairy, number of the florets per head were taxonomically most important to differentiate these species. Among these species it was observed that A. absinthium Linn. was mostly used against liver diseases.

  Tehsil Gujar Khan is a typical example of Potohar region characterized by the natural beauty and specific cultural heritage. Only one family represented Pteridophytes, Gymnosperms by three families and Angiosperms by 66 families (10 monocots and 56 dicots). About 271 plants were enlisted from the study area in which 206 species of plants (76.01%) are herbs, species are trees (16.60%) and about 20 species are shrubs (07.38%). As for as conservation status of plants species is concerned 8.12% are abundant, 4.65% common, 2.14% uncommon, .71 rare and 7.38% of species are very rare. The results of utilization of plants showed that some plants have multiple uses. Based on utility, there were 197 medicinal plants (72.69%), whereas 76 species (28.04%) served as fodder and forage for animals, 2 species (15.49%) were used as fuel wood, species (17.34%) served for attracting honey bees, 2 species (11.81%) were used as vegetables and pot herbs, species (12.91%) used for thatching, sheltering and roofing, 1 species (11.43%) were planted as ornamental, species (9.96%) used for making various agricultural appliances and ropes, 1 species (07.74%) were timber yielding, 0 species (7.38%) were used for fencing and hedges whereas 22 species (08.11%) each were serving for the Category of fruit yielding plants. Lastly 7 species (02.58%) were serving as a source of spices and condiments. The species within a stand were arranged on the basis of importance values and named after the three leading species with the highest importance value as dominant; the closely approaching species were considered as co-dominant and followed by associated and rare species on the basis of I.V. So following four communities were found namely, Acacia-Aristida -Gnaphalium community, Poa-Acacia-Cymbopogon Community, Inula-Tamarix-Chenopodium community and Acacia-Prosopis-Imperata Community.

  Parthenium hysterophorus is a new entry and successfully growing on all types of soils in fields and waste lands. Parthenium is drought resistant highly resistant weed which sustain its survival in highly unfavorable conditions where other delicate flora can not grow. Due to its allelopathic nature, no other plant can grow near it successfully and the chemical nature of the soil also changes which further accelerate the unfavourness for the other species. Because of the weedy characteristics and production of large number of seeds, it grew on an alarming rate and presently it has occupied the large areas in NWFP and Punjab with increasing tendency. It has been found that this weed can grow in association of many other plants of which Cannabis sativa is more important but further studies indicated that even Cannabis is replaced by this weed which means it is highly tolerant and hardy in its nature and due to absence of some natural enemy (Predate) it tends to grow on unprecented rate. During the present study it has been observed that Parthenium can grow in variety of soil types with different pH values. Mostly sandy loam and sandy clay loam are found highly conductive for its growth. It is nature of its wide adaptability of various soil types due to which it is found replacing the Cannabis and other natural flora. However, well grown Cannabis plants compete for survival with this weed.

  Pakistan has very significant mountain ranges; the Hindukush, Karakurm and Himalaya. Hindukush mountain ranges further extend from the northeast to the southeast to the southwest upto Koh-Safed. These mountain ranges contain some of the highest peaks of the world i.e., K2 (9861 m), NangaParbat (8126 m), Rakaposhi (7788 m), Trich Mir (7690 m) and Deosai Plateau (4333-5333 m). The most of the flora of Pakistan (About 70%) occur in the mountains, in diverse ecological zone or habitats. The following important areas with natural vegetation have been surveyed during rainy season: North Chitral, North Swat, Kaghan Valley, Gilgit and Skardu including Deosai Plateau. The natural lakes of the same areas were also surveyed such as Saif ul Maluk, Lulusar, Sadpapra, Kachura, Shoezal. Their natural vegetation/forests were mostly consists of Pinus wallichiana, P. roxburghi, Abies pindrow, Quercus incana, Juglan regia, Juniper, Betula utillis, shrubs, herb and grasses. They were growing at various altitudes and ecozones: Sub-tropical pine zone 12 species; Temperate zone 24 species, Sub- alpine 20 species; Alpine zone 10 species. There are number of medicinal mushrooms, common genera were: Agaricus, Clitocybe, Calvatia, Coprinus, Coriolus, Fomes, Ganoderma, Morchella and Podaxis. The terrestrial environment under these forests was rich in organic matter, which was derived by the activity of a number of organisms: fungi, bacteria and invertebrate etc. More than fifty species of medicinally important Mushrooms belonging to 40 genera have been recorded. They may be Mycorrhizal, parasitic, saprophytic, terrestrial/coprophillous in their habitat.
