Palynotaxonomy of Monocots and Dicots

In this article we will discuss about the palynotaxonomy of monocots and dicots. Palynotaxonomy of Monocots: Monocotyledoneae: Pandanales: The pollen grains are monoporate to monosulcate. Typha latifolia (Typhaceae) grains are in tetragonal tetrads, other species of Typha show monads, monoporate; exine granulate to reticulate. In Pandanaceae the grains are monoporate to monosulcate; exine psilate to echinate. In Sparganiaceae, grains are [...]

Evolutionary Trends among Pollen Grains

In this article we will discuss about the evolutionary trends among pollen grains based on palynotaxonomical works. Primarily the aperture is proximal in position in all the taxa of plants, and a change from proximal to distal has been conditioned by physiological and ecological needs that arose in the wake of the origin of new plant taxa. The bryophytes and [...]
