Aquatic and Semi-Aquatic Plants of the Lower Ganga-Delta. Its Taxonomy, Ecology and Economic Importance. 1990. 4 col. plates. XIV, 408 p. gr8vo.Cloth.

In the book the author discussed in brief the angiosperm flora of the fresh-water environment from the lower Ganga Delta regions of West Belgal. This individual flora should be familiar in terms of their correct nomenclature, identity, key notes, ecological set-up, phenology, physiognomy and economic importance as well. It is also pointed out how far these plants are weedy and how these can be controlled and/or utilized. There is a common belief that in the Universe each and every individual is correlated; without one the other cannot successfully complete their life cycle. So, for our own benefit and to avoid the pollution or to keep the nature in balance like others, these aquatic ecosystems should be conserved and scientific means and methods should be applied. Taking this view in mind, the flowering plants of the freshwater ecosystems (327 numbers) are discussed in relation to its taxonomy, ecology and economic importance or potentialities. All these plants were collected from the field by the author himself who studied the above subject at the field, the herbarium and laboratories. The experimental trials have also been made in the laboratories and in the agriculture and aquaculture ponds as well.
