  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.

  Pollen morphology of two different species, Tragopogon dubius and Tragopogon gracilis, belonging to genus Tragopogon of family Asteraceae was studied from Pakistan. Morphology of pollen grains of each of the species is based on specimens selected at random. Proposed characters i.e. grain, shape of pollen grain, equatorial view, polar view, equatorial diameter (E), polar diameter (P), P / E ratio, length of colpus, exine surface, exine thickness, inter poral distance, inter spinal distance, inter spinal outline, length of spines, number of spines between colpi in each species were recorded for comparison. At species level, micromorphological differences and distribution of surface pattern, shape and size of pollen have been found to exist. The pollen grains are consistently echinate, trizonocolporate but in Tragopogon dubius pollen grains are tetrazonocolporate. Maximum, equatorial view, polar view, equatorial diameter (E), polar diameter (P), P/ E ratio, length of colpus, exine surface, exine thickness, inter poral distance, inter spinal distance, inter spinal outline was observed in and Tragopogon gracilis and length of spines is maximum in Tragopogon dubius. This study demonstrates the potential of pollen studies in distinguishing some taxonomic groups in the Asteraceae.

  Pollen morphology of four different species, Crepis flexuosa, Crepis multicaulis, Crepis sancta and Crepis thomsonii, belonging to genus Crepis of family Asteraceae were studied from Pakistan. Morphology of pollen grains of each of the species is based on 20 specimens selected at random. Proposed characters i.e., grain, shape of pollen grain, equatorial view, polar view, equatorial diameter (E), polar diameter (P), P / E ratio, length of colpus, exine surface, exine thickness, inter poral distance, inter spinal distance, inter spinal outline, length of spines and number of spines between colpi in each species were recorded for comparison. At species level, micromorphological differences and distribution of surface pattern, shape and size of pollen have been found to exist. The pollen grains are consistently echinate and trizonocolporate. Maximum equatorial diameter, polar diameter and colpus length was observed in Crepis multicaulis while in Crepis flexuosa spine length and exine thickness is found top be maximum. Inter poral distance is minimum in Crepis flexuosa. Inter spinal distance & P/E ratio is higher in Crepis thomsonii. This study demonstrates the potential of pollen studies in distinguishing some taxonomic groups in the Asteraceae.

  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.

  The genus Sonchus L. belongs to the tribe Lactuceae in family Asteraceae/Compositae whose taxonomic study has been carried out from Pakistan. Its seven species were studied namely Sonchus asper, S. oleraceous, S. tennerrimus, S. uliginosus, S. palustris, S. arvensis and S. maritimus. In Sonchus arvensis radical and cauline leaves are runcinate, pinnatifid, spinate, margin toothed, caudate and glabrous. In S. arvensis the achenes oblanceolate,+ 7 ribs on each face and in S. asper achenes compressed, + 3 ribs on each face. In S. maritimus lateral lobes of leaves are incised and glabrous. Sonchus palustris has glandular hairs on stem, achenes has + 3 ribs on each face and neck absent. In S. tenerrimus achenes compressed thick margined, 5-ribbed appearing 1-ribbed and 2-grooved on each face while in S. uliginosus achenes lanceolate + 4 ribs on each face, pappus 0.7 cm long, neck absent. It is concluded that in plant taxonomy morphological characters have given great weightage in identification and classification of plants. In this research project the species Sonchus palustris has been reported first time from Pakistan

  The genus Launaea L. belongs to the tribe Lactuceae in family Asteraceae/Compositae whose taxonomic study has been carried out from Pakistan. The genus Launaea belongs to the tribe Lactuceae of Asteraceae. In this genus eight species were considered for morphological study i.e. Launaea intybacea, L. aspelinifolia, L. capitata, L. procumbens, L. microcephala, L. spinosa, L. massauensis and L. residifolia. Material for taxonomic studies was obtained from naturally occurring population and from herbarium of Quaid-i-Azam University (ISL). In Launaea asplinifolia the achenes are elliptical, + 5-ribs are present on each face and neck absent. In L. capitata the leaves are mostly basal while L. intybacea leaves ½ amplexicaul, auriculate, auricles rounded with long fine points. Launaea microcephala differs from Launaea procumbens in being annual, sparsely pubescent to villous herb and in possessing terminal heads on the dichotomously branched flowering stem, involucral bracts many-seriate, and the achenes are of one type.
