The present study deals with the pollen morphological diversity and taxonomic importance among the Phyllanthus species belonging to the Phyllanthaceae family from combined Andhra Pradesh. Sixteen species belonging to genus Phyllanthus analyzed the pollen morphology using SEM. The size, shape, symmetry, aperture and ornamentation were recorded in all test species, among them ten were tricolporate, three tetracolporate while the remaining indicates the pantosyncolpate. The reticulate ornamentation is common and predominant in all taxa. The evaluation of taxonomic diversity among Phyllanthus species hitherto not known from Andhra Pradesh, hence the present study is the first report and gains importance. It is clear that the pollen characteristic features are significant in the identification of endemic species (P.scabrifolius and P.narayanaswamii) and confirmation of potential medicinal plants (P. amarus and its allied species) with the help of micromorphological pollen studies.

Angiosperms (flowering plants) are strikingly diverse. This is clearly expressed in the morphology of their pollen grains, which are characterized by enormous variety in their shape and patterning. In this paper, I approach angiosperm pollen morphology from the perspective of enumerative combinatorics. This involves generating angiosperm pollen morphotypes by algorithmically combining character states and enumerating the results of these combinations. I use this approach to generate 3 643 200 pollen morphotypes, which I visualize using a parallel-coordinates plot. This represents a raw morphospace. To compare real-world and theoretical morphologies, I map the pollen of 1008 species of Neotropical angiosperms growing on Barro Colorado Island (BCI), Panama, onto this raw morphospace. This highlights that, in addition to their well-documented taxonomic diversity, Neotropical rainforests also represent an enormous reservoir of morphological diversity. Angiosperm pollen morphospace at BCI has been filled mostly by pollen morphotypes that are unique to single plant species. Repetition of pollen morphotypes among higher taxa at BCI reflects both constraint and convergence. This combinatorial approach to morphology addresses the complexity that results from large numbers of discrete character combinations and could be employed in any situation where organismal form can be captured by discrete morphological characters.

The aim of the present study was to investigate the presence of phyto chemical, antimicrobial activities and micro propagation of the selected medicinal plants i.e. Rauwolfia serpentina, Adhatoda vasica and Alstonia scholaris. These endemic plants belong to Apocynaceae and were collected from higher altitudes of Eastern Ghats, Lambasingi forest region, Andhra Pradesh India. To determine the total phenolic and flavonoid contents, Soxhlet apparatus was used for this study. Solvents used were in this study are water, ethyl acetate, chloroform and methanol. Among them the solvent methanolic extract of Rauwolfia serpentina (57.15±1.2) and Alstonia scholaris (55.06±0.7) showed high content of saponins. The test microrganism which were studied against the efficacy of selected medicinal plant extracts were, two bacterial strians i.e., Streptococcus pyogenes, Pseudomonas aeruginosa and two fungal strains Aspergillus niger and Vibrio cholera. The antimicrobial activity was proved that the methanol extracts was found to be maximum antimicrobial growth inhibition. The simple and effective protocol was developed to propagate the Rauwolfia plant from nodal explants. Maximum no of 95% plantlets regenerated successfully. These propagated plantlets were hardened to survive in vivo conditions.

Palynomorphological characteristics of Campanula lingulata, the Balkan-Carpathian endemic species growing in Serbia, have been investigated using light microscopy and scanning electron microscopy for the first time, in order to provide some information helpful for a better understanding of the taxonomic position of this species within the genus, as well as to contribute to the pollen atlas of Serbian apiflora. The pollen grains are radially symmetrical, isopolar, 3-zonoporate and medium-sized monads oblate-sphaeroidal in shape. Mean of the polar axis (P) is 27.6?1.9 ?m, while the average length of the equatorial axis (E) is 28.8?1.6 ?m. The apertures are operculate. The sculpturing pattern of the exine is microre?ticulate-microechinatae. The exine surface is covered with evenly distributed supratectal spinules of variable length and sparse granules. The longest supratectal spinules are 0.64?0.05 ?m in length and the smallest sculptural elements are less than 0.2 ?m high. The microechinae density per sample area of 5 ?m x 5 ?m averages 17.4?2.4.

It is vital to record and preserve indigenous knowledge on plants to prevent loss of this valuable information. The indigenous knowledge about herbal drugs can provide us with useful information, such as their phytotherapeutic activities for the treatment of various diseases. This study investigated the indigenous knowledge regarding the use of medicinal plants for the treatment of human diseases and disorders in Khalil Abad region, Zarrin Dasht County, Fars province (Iran) from January to May 2017. Questionnaires were distributed among the subjects and traditional herbal information were recorded. The medicinal plants in this region are predominantly bush, including Zataria multiflora Boiss, Peganum harmala L., Alhagi persarum Boiss. & Buhse and Astragalus sp. The results of this study indicate that the residents of Khalil Abad village use various medicinal plants for nutritional and medicinal purposes. This is the first report of the ethnobotany of the region and the medicinal plants of indigenous knowledge of this region could be used as a source for new drugs.

Indobanalia thyrsiflora is an endemic species occurring in peninsular India (Andhra Pradesh, Karnataka, Kerala and Tamil Nadu States) and Sri Lanka. A nomenclatural study of the basionym Banalia thyrsiflora, published by Moquin-Tandon in Candolle’s Prodromus (year 1849), is carried out and the name is lectotypified on a specimen deposited at P (barcode P00609924); isolectotypes are traced at K and CAL. A preliminary morphological characterization of the species is also given, based on field surveys and examination of herbarium specimens. We noted that I. thyrsiflora is highly variable. However, we prefer to avoid, for the moment, taxonomic conclusions about the various morphotypes found, waiting the complete results of this ongoing morphological and molecular investigations.

Abstract Delimiting species boundaries is a complex challenge usually hindered by overlooked morphological diversification or misinterpretation of geographically structured phenotypic variability. Independent molecular data are extremely useful to characterize and understand such morphological diversity. Morphological and molecular variability of the non-phoretic and apterous, widely distributed, giant blister beetles of the genus Berberomeloe, were investigated within and between lineages across most of the distributional range of the genus. We used two mtDNA gene fragments to characterize genetic variability and to produce a time-calibrated phylogeny of the genus. Our results reveal several mitochondrial lineages, allopatrically, parapatrically and sympatrically distributed. Most clades are not distinguishable between each other based on morphometrics. However, no morphometric overlap is observed between two closely related clades, one of them occurring in sympatry with a distantly congeneric species (B. insignis), suggesting that sympatry could trigger morphological diversification. Although most species share a morphometric space, they can be morphologically identified by a combination of easily observed characteristic qualitative features. Based on the concordance between mtDNA clades and morphological units, we describe six new species of Berberomeloe (B. castuo sp. nov., B. comunero sp. nov., B. indalo sp. nov, B. yebli sp. nov., B. payoyo sp. nov. and B. tenebrosus sp. nov.), revalidate two taxa (B. maculifrons comb. nov. and B. laevigatus comb. nov.) and redefine B. majalis.

The genus Anabaenopsis comprises about 20 morphospecies distributed in plankton of tropical, subtropical and temperate regions during warm periods. The morphological diversity and population dynamics of Anabaenopsis species from one artificial shallow lake from the Province of Buenos Aires, Argentina, was studied during summer 2005 and 2006; and from April 2012 to May 2014. The most common and abundant species were identified as A. elenkinii and A. cf. cunningtonii (first report in Argentina). Anabaenopsis circularis and A. milleri (first report in the American continent and Argentina) were less common, whereas A. nadsonii was rarely observed. Almost all species contributed to algal blooms during warm periods. However, some species were registered even under the lowest temperatures recorded (7.5 °C) and sustained biovolume also during winter (A. milleri, A. elenkinii and A. cf. cunningtonii). These results indicate that some species of the genus are capable of growing at temperatures much lower than 20°C. The species richness noted in this study suggests that there is likely much more diversity remaining on this genus to be reported in Argentina.
