These included Abrus precatorius Linn. and A. pulchellus Thw, two circumtropical species from India and A. canensis Welw. ex Bak. and A. fruticulosus W. & A., two species from continental Africa. The fifth species was also A. precatorius but with white seeds. Pairing affinity values of this species was highest with A. precatorius having red black seeds but varied considerably in their protein profile. A. precatorius was also found to be more related to the other Indian species A. pulchellus . On the other hand A. pulchellus which has been placed as a separate species by Verdcourt but considered to be a subspecies of A. fruticulosus by Breteler, were found to be two separate species. A. precatorius and A. fruticulosus are the most distantly related species.

Our result shows that butterflies of Howrah district, West Bengal, India comprises of 106 species including 75 genera and 6 families. Out of these 6 families Lycaenidae and Nymphalidae were to found to be the most dominant in nature. During our studies, we found Grass Jewel, the smallest butterfly in India and The Blue Mormon, the largest butterfly of South West Bengal as well as second largest in India. Common Shot Silverline, Angle Sunbeam, Bengal Plains Blue Royal and Indian Oak Blue recorded the first time from the district. Rapid urbanization and building of industries are the serious threats to butterfly diversity in this district. So, preparation of a list of butterfly species is necessary for further references to understand the changes of their diversity.

Khejuri-II and Nandigram-I block were damaged remarkably. In those two blocks, most old trees were broken, uprooted, or both. Significant loss of plant diversity was occurred by this severe super cyclone. Still, the most predicted point for the landfall of Amphan Digha under Ramnagar-I block was affected in minimum level. It was noted that throughout the Midnapore coastline, manmade vegetation was damaged maximum. Mainly Casuarina and Eucalyptus trees were affected very much. Trees were more damaged rather than shrubs and herbs. Mangrove plants just in front of the sea line were destroyed less than backside manmade terrestrial vegetation.

This family characterized by unique features that contributes to extreme floral complexity and diversity. In this paper, we used preliminary phylogenetic hypothesis for the family Asclepiadaceae to explore the mode of diversification in pollinarium and coronal structure. The occurance, size, shape, position, orientation of pollinia, mode of pollination and the presence of form of coralline corona and gynostegial corona were studied for similarity indices between two subfamilies Periplocoideae and Asclepiadoideae.

The flower is a primary reproductive character considered to be more important than any vegetative characters. The mass of pollen grains is basically called pollinia. Like pollen, the pollinium is also the key character for the identification of specific plant species belonging to the family Asclepiadaceae (Dicotyledons) and Orchidaceae (Monocotyledons). Pollinial characters are now being used as important taxonomical tool for reassessing the different types of plant groups. The morphological nature of pollinia is specific in each genus. The morphological diversifications of pollinium of different genera of Asclepiadaceae were studied with the help of light microscope and phase contrast microscope (Leica-DM1000). The shape, size, position, orientation of pollinia, translator attachment, furrow position, etc are important criterion for the studies of pollinial morphology. This study analyzed the pollinial morphology of some selected plant taxa like Calotropis gigantea (L.) Ait., Daemia extensa R.Br., Dregea volubilis Benth, Gymnema sylvestre R.Br, Hoya globulosa Hook.f. and Tylophora indica (Burm.f.) Merr. collected from different parts of West Bengal.

Spreng, S. chrysocoulos Spreng, S. kraussiana A. Br., S. monospora Spreng] by Thin layer chromatography with a view to understand the biochemical and physiological nature and homology among the different parts of the plant. A comparison of the free amino acid composition indicates that amino-n-butyric acid, arginine, aspartic acid, glutamic acid, glycine, hydroxyproline, leucine, ornithine, proline, serine and tryptophan, which were present in rhizophores, were also detected in the stem and roots. However alanine was found only in the rhizophores and stem but not detected in roots while phenylalanine was detected only in the rhizophores and root but was not detected in the stem. Simultaneously considerable homology was observed in the amino acid composition between the stem, roots and rhizophores of different species.

A comparative micro -morphological study of stomata of 45 genera belonging to 3 families viz. Fabaceae (19 genera and 24 species), Caesalpniaceae (6 genera and 11 species) and Mimosaceae 8 genera and 10 species) under the order Leguminales was done. The selected species showed diversity in the habits and habitats also. Among the 45 selected species the 19 species are terrestrial and trees, 5 species are shrubs, 12 species are herbs, 7 species are climbers and 2 species are fully i n marshy habit. Leaf clearings and cuticular preparations were examined with light microscopy. Out of the 45 selected species, 31 species showed amphistomatic and 14 species showed hypostomatic and on the other hand the most diversified stomata were obse rved tree species. The maximum numbers of tree species have hypostomatic which reflects that the habits and stomata appearance on foliar epidermis might be greatly co -related. The size and shapes of stomata are also varied in the tree species which bear la rger size of stomata in respect of other habits and habitats. Three types of stomata were observed viz. paracytic (64.1%), anisocytic (46.6%) and anomocytic (33.3%). Among these 3 types of stomata the paracytic type of stomata are very common and than othe r. The structure, shape and size of stomata varied among the different families and even within the family in between the various genus and species also.

Alternanthera philoxeroides, alligator weed is an invasive species. A. philoxeroides have been allelochemicals. Chemicals released from plants and imposing allelopathic influences are allelochemicals or allelochemics. Allelochemicals produced in the tissues of such plants may enter soils as leaf leachates or root exudates or during tissue decomposition [1]. Chemicals with allelopathic potential are present in almost all plants and in many tissues such as leaves, stems, inflorescence, fruits, seeds, roots that these chemicals under specific conditions are released in to the environment and can positively or negatively affect on growth and development of vegetation [2]. Allelopathic compounds influence physiological processes such as cellular expansion, cell wall constraction, phytohormonal balance, activity of specific enzymes like indolacetic acid oxidase, pollens, spores and seeds germination, mineral uptake, stomatal movement, pigment synthesis, photosynthesis, respiration, protein synthesis, leghemoglobin biosynthesis, N 2-fixation, plant water relations, DNA and RNA modification and activation of cellular antioxidative [3,4]. An aqueous leachates from inflorescence, stem, root and leaves of Alternanthera philoxeroides Grisebach were found to inhibit the germination and seedling growth of Ampelopteris prolifera (Ketz.). Allelopathic inhibition is complex and can involve the interaction of different classes of chemicals like phenolic compounds, flavanoids, terpenoids, alkaloids, steroids, carbohydrates and amino acids with mixtures of different compounds sometimes having a greater allelopathic effect than individual compounds alone. Allelochemicals may be more biodegradable than traditional herbicides but may also have undesirable effects on non-target species, necessiating ecological studies before widespread use. Although, seedling must be done in a suitable moisture and temperature. Reports indicate that some allelochemicals to inhibit the germination. Therefore, in the present study, the effects of some
