    Pollen and Spore Morphology/ Plant Taxonomy by Erdtman, G. and a great selection of related books, art and collectibles available now at The pollen morphology of 12 Brazilian native species of Malpighiaceae from forest fragments was investigated in search to expand the morphological knowledge of the species analyzed thus contributing to its palynology, taxonomy, and conservation. The pollen grains were acetolysed, measured, photographed using light microscopy and scanning electron microscopy, and described qualitatively.

    In an earlier paper, which includes pollen descriptions for 93 genera and approximately species of the large tropical family Annonaceae, the auth We use cookies to enhance your experience on our continuing to use our website, you are agreeing to our use of cookies.   Pollen evidence from our study supports this hypothesis, as the pollen morphology of the species from the Himalayas and Hengduan Mountains contain all of the pollen types in the genus Lilium. It should be emphasized that the Formosanum type of pollen can be found in the genus Nomocharis, which is restricted to the Himalayas and Hengduan.

    The unique pollen morphology may be related to mechanical processes to accommodate the increase in volume after early formation of the pollen wall and may indicate a relationship to an. In part, the pollen data reinforce the traditional view of closely related pairs or small groups of genera. In Berberis and Mahonia the pollen morphology would support separate family status as well as congeneric treatment. The unusual exine structure in Nandina would reinforce its treatment as a monotypic family, Nandinaceae.

The main aims of this study are to contribute to our understanding the pollen morphology of aquatic plants naturally growing in four northern Mediterranean lakes of Egypt namely: Mariut, Idku, Burullus and Manzala by light microscopy and to be used as additional tool for plant taxonomy.

Materials and methods Study area. The pollen morphology data support taxonomic arrangements at different levels: the separation of the family into two subfamilies, Eriocauloideae and Paepalanthoideae, the separation from Syngonanthus of sect. Eulepis by its 2-zonasulcate pollen grains and the segregation of Tonina fluviatilis, due to its grooved spines, into its own genus.

From the student's point of view the pollen material for detailed pollen morphological study is easily accessible. The pollen of this family vary from monads to polyads.

pollen morphology by early Botanists has demonstrated the potential value of palynology in phylogeny and plant taxonomy. The contribution of Woodehouse, () through the publication of the book “pollen grains” marked the beginning of purposeful studies on pollen morphology in angiosperms.

Palynology is the scientific study of pollen and spores, those virtually indestructible, microscopic, but easily identifiable plant parts found in archaeological sites and adjacent soils and water tiny organic materials are most commonly used to identify past environmental climates (called paleoenvironmental reconstruction), and track changes in climate over a period of time.
