  Pollen fertility of seven different species, Launaea secunda, L. acualis, L. aspeliniifolia, L. capitata, L. procumbens, L. residifolia and L. secunda belonging to genus Launaea of family Asteraceae was studied from Pakistan. Morphology of pollen grains of each of the species is based on specimens selected at random. At species level, micro-morphological characters like pollen fertility differences and distribution of surface pattern, shape and size of pollen have been considered found to exist. Pollen fertility data shows that L. residifolia is having the highest value 98.84 while the least value was found in the Launaea acuais 78.41%. Further cytological studies are required in taxonomy to determine the fertility status in different species. This study demonstrates the potential of pollen studies in distinguishing some taxonomic groups in the Asterasceae.

  The present study was carried out to assess, record and report the ethnobotanical potential of the Kala Chitta Hills (salt range) of District Attock. Results of the present investigation were based on medicinally important 40 species (21 families). These plant species has other benefits too along with their major utilities like apiculture, sericulture, food and fruits. The Kala Chitta Hills of the Salt Range are very unique. Due to increase in population masses, demands of people increases, causing great pressure on the products of the area. This continuous pressure for last few decades has disastrously damaged the natural characteristic ecosystem of the area. The region is very rich in having medicinal plants. To understand the indigenous knowledge of the local people through ethnomedicinal study is very important for creating awareness among them regarding sustainable natural resource management. About 100 informants including local people, hakims and medicinal businessmen were interviewed for collection of ethnomedicinal data through the questionnaire. Results were compiled, issues were discussed, conclusion was made and recommendations are suggested for the future.

  An ethnobotanical project was carried out to investigate conservation status of the flora of Utror and Gabral. The twin valleys are located in the remote northwestern part of District Swat. The area is gifted with diverse and unique flora, as it is adjacent to the confluence point of Himalayas, Hindu-Kush and Karakorum. Over exploitation of plant resources combined with improper harvesting and post harvesting techniques have intensified pressure on ethnobotanically priced flora of the area. Present study revealed that 17.61% of the total utility plants of Utror and Gabral valleys are threatened, of which 4.54% are Endangered, 5.68% Vulnerable, 4.54% Rare and 2.84% Near Threatened. The study confirmed that the area possesses great potential for cultivation and sustainable harvesting of economically important plant resources. Species like Colchicum luteum, Dioscorea deltoidea, Bistorta amplexicaulis, Caltha alba, Valeriana jatamansii, Viola biflora, Viola canescens, Polygonatum verticilatum, Acorus calamus, Podophyllum emodi, Saussorea lappa, Paeonia emodi and Geranium wallichianum can be introduced as marginal crops in the area. Conservation status of Acorus calamus, Podophyllum emodi, Saussorea lappa, Polygonatum verticilatum, Paeonia emodi, Ephedra gerardiana, Bunium persicum and Berberis vulgaris indicate that these plant species need special attention before they are eroded genetically.

  Lactuca is an important genus of tribe Lactuceae in Asteraceae. In Lactuca serriola the chromosome number, various meiotic stages, formation of pollen grains and pollen morphology is taken into account. Meiotic studies indicated that basic number of chromosomes is nine, n=9, (2n=18). In this species the meiosis was regular and pairing of homologous chromosomes was normal. During anaphase all the chromosomes moved regularly to the opposite poles. The chromosome bivalents are pronounced in diakinesis. Tetrad developed into pollen grains, whose equatorial and polar views were observed. The pollen grain is trizonocolporate in polar view. The pollen grain is echinate or spinate. It is recommended that the techniques like karyological and palynological study in connection with morphology must be carried out in correlation with the taxonomy on larger scale to find the variation and evolution in native species of the genus.

  A study was conducted in Kahuta to enlist the medicinal plants. The inhabitants of the area have to use the medicinal plants for various purposes and have for a long time been dependent on surrounding plant resources for their food, shelter, fodder`s, health, care and other cultural purposes. However changes in their life styles are responsible for the decrease of practice in the local use of herbs for medicine. It is, therefore, felt worth while to record the native uses of these plants before the information is to be lost. In total 25 species of herbs belonging to 18 families were recorded, used medicinally by inhabitants of the area . Some of the most interesting and representative plants of the area are : Cyperus rotundas L. which is mainly used for cholera ,dyspepsia and fevers. Saussuoria heteromala D. Don is used as a tonic for animals . The oil of Pongamia pinnata (L.) Merrill is externally applied to cure herpes and eczema .Leaves of Euphorbia helioscopia L. are given to cure mad dogs . Boerhavia diffusa Linn.is useful for jaundice and liver complaints .

  The aqueous extracts from different plant parts showed variable results. Both the suppressing and the stimulatory effect of E.microtheca were noticed on radicle and plumule growth and seed germination of Pennisetum glaucum (L) R.Br. cv. BARI-Hairy. The toxicity and stimulation varied from part to part. Exudates from fresh roots were highly toxic while whole plant exudates were highly exhilarating for the radicle growth. For plumule growth, whole plant extract was highly toxic and stem extracts were highly enhancing. No extract, irespective of its origin, concentrations and incubation periods could produce a detrimental effect on seed germination of the test plant.

  This paper is based on the results of an ethno-botanical research conducted in Shogran valley (Hazara). Information on local names, traditional medicinal uses and occurrence of the herbs, shrubs and trees has been presented. A total of 77 species of herbs, 12 species of shrubs and 18 species of trees were recorded that are used medicinally and for other purposes. Among herbs Ajuga bracteosa Wall. ex Bth., Convolvulus arvensis L. , Geranium nepalense Sweet, Geranium wallichianum D. Don ex Sweet, Mentha longifolia (Hk.) Huds., Podophyllum hexandrum Royle, Potentilla nepalensis Hk., Tori/is nodosa (L.) Gaertn., Valerian a jatamansi Jones and Viola canescens Wall. ex Roxb. are the most common. Podophyllum hexandrum is vulnerable due to over exploitation. Five species of shrubs and 1 2 species of trees are collected for sale in the local market as well as in other parts of the country. Juglans regia L. is found vulnerable in this area due to utilization of its different parts for different purposes. Melia azedarach L. is found under pressure of being used as fuel wood. Wild fruits such as Ficus carica L., Diospyrus lotus L., Morus alba L., Pyrus communis L., Pyrus pashia Ham. ex D. Don. and Prunus persica (L.) Batsch. require in situ conservation in the area for future germplasm source.

  Abaxial and adaxial leaf epidermal anatomy of four related species having morphological resemblances have been studied. These taxa showed variation in short and long cells, silica bodies, macro and micro hair, presence or absence of stomata and shape of subsidiary cells. Most of these characters are diagnostic and have been used for making keys. Hence, on the basis of leaf epidermal anatomy we can distinguish among Cymbopogon citrates (DC.) Stapf, Cynodon dactylon (L.) Pars, Panicum summatrense Roeth ex Roem & Schult and Viteveria zizanoides (L.) Nash.
