Forensic palynology is the application of pollen and spores in solving legal issues, either civil or criminal. Palynology is also invaluable to evolutionary and taxonomic research and can help to delineate phylogenetic relationships between fossilized and extant plants.

The exine pattern has been useful in recognizing different species of Bauhinia. The two families, Araceae and Lemnaceae under the same order Arales of Hutchinson are characterized by stenopalynous, 1-2-4-colpate, 3-porate or inaperturate and Arecaceae exine sculptured pollen in the former, while the latter is characterized by eupalynous, 1- porate and spinose pollen. Pollen size is helpful in distinguishing two species of Malva, M. rotundifolia (pollen 74- 84 µm) and M. sylvestris (pollen 105-126 µm).

This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. TOS4. Amongst the eurypalynous taxa some may be natural and others quite heterogeneous. Meaning of Taxonomy: The term taxonomy is derived from the Greek words (‘taxis’ means arrangement and ‘nomos’ means law). (c) The embryo and endosperm in the new sporophyte. What is a trophic hormone? In the family Betulaceae, the thickening of exine around the pores make a distinguishing character for different genera, which is knob-like in Betula, club-shaped in Corylis, unexpanded in Caprinus, and an arcus is present between adjacent pores in Alnus. /Parent 2 0 R View Academics in Taxonomy, Palynology, Spores and Pollen on Academia.edu.

Sharma (1987) investigated the pollen morphology of 16 Indian species of Cyperus, and prepared a key to differentiate all of them on the basis of pollen characters. Following are a few examples: Pollen morphology does not support sharp demarcation between the dicotyledons and the monocotyledons as suggested by most systems of classification, because dicotyledonous pollen characters occur in some monocotyledons and vice versa.

The phases of palynology that deal exclusively with fossils are outgrowths and extensions of techniques and principles developed in the study of peat deposits of northern Europe during the early 1900s. However, as the role of palynological taxonomy is more or less confined to the general anatomy and morphology of the pollen grain or spore, as viewed in the surface, facilitates the identification of these structures becomes a prime object of the palynologist involved.
