The present research work emphasis on the phytochemical and biological evaluation of Anagallis arvensis (aerial and root parts) which belongs to family Primulaceae. The dichloromethane and methanol extracts of aerial and root parts were prepared. The extracts were subjected to a series of biological screening assays i. e antioxidant assay (2, 2-diphenyl-1-picryl hydrazyl and ferrous reducing power assay) and enzyme inhibition assays (Urease, Acetylcholinestrase and α- glucosidase inhibitory assays). The dichloromethane extracts from aerial and root parts showed significant antioxidant activity (71.5±0.3% and 73.5±0.3% respectively) while methanol extracts of aerial and root parts of the plant showed good antioxidant activity (65.3±0.3% and 64.4±0.2% respectively). When the extracts were screened for anti- urease activity significant (76.94±0.23% with IC50 142.53±0.19) and moderate (59.27±0.23% with IC50 187.41±0.19) results were found with methanol extracts of aerial parts and root parts respectively. The methanol extracts of root parts also showed moderate (51.82±0.15% with less than 500) acetylcholinestrase inhibitory activity. Dichloromethane extracts showed significant (97.62±0.13% with IC50 19.73±.03 and 89.26±0.19% with IC50 119.75±0.15) α-glucosidase inhibition respectively. Methanol extracts showed significant (91.54±0.17% with IC50 87.24±0.12) and good (62.53±0.21% with IC50 232.28±0.17) α-glucosidase inhibition. The plant powdered material was subjected to phytochemical investigations for presence of secondary metabolites, the results revealed the presence of saponins and flavonoids. V 1. INTRODUCTION Plants existence is universal which account for the variety of vast usages like beverages, medicines, dyeing, nutrition, fragrances, pharmaceutical and also for industrial purposes. Plants play a vital role in life and its growth and the importance cannot be ignored at any stage. Along with a vigorous and eco-friendly environment, plants produce food which is very important for our survival (Siddiqui et al., 2009). Humans have been gaining proteins, carbohydrates, fats and minerals from plants for millions of years and also build homes for their protection. Apart from primary ingredients, plants serve as a vital source of secondary metabolites which are used as agrochemicals, flavors, food additives, colorants, pharmaceuticals and bio-pesticides (Hassanpour et al., 2011). People have accepted the use of medical plants as alternative treatment since long time and the effects are less likely adverse. Old studies pour a light on enhancing immunity against various diseases using traditional systems. Also recent researches favor natural anti-oxidant compounds against the use of synthetic drugs (Subramanian et al., 2011). In traditional system of medications, plants have played a vital role in cure or prevention of different diseases. Treatments were not only limited to humans but animals as well have been cured with plant formulated medicines. This system has also been adopted by conventional Chinese system of medicines. Contemporary science also acknowledges the importance of plant based medicines and included it in pharmacotherapy as wide range of medications (Nasri, 2015). 1.1 Historical Sources and Evolution of Indigenous Plants and Medicine System There was a common practice in ancient times that medicinally valued plants were used for their specific actions against specific disease. For treating some particular ailment ancients use different parts of these plants as they were enriched with medicinal worth. Similarly Ayurvedic, Suddha and Unani medicinal indigenous system has been used and practiced from centuries and still exists (Bhattacharjee, 2004) (Gupta and Sharma, 2006). Healing and treatment of ailments with the aid of plants having medicinal importance is as old as human being is itself. The relationship between human beings and his efforts for the drugs search in nature evidenced from the far past. Although there are abundant evidences from numerous sources: preserved monuments, written documents. One of the 1 oldest evidence in written form is on usage of medicinal plants for preparation of different drugs for treatment of different diseases have been related to a Sumerian clay slab about five thousand years aged from Nagpur. It consists of twelve standard operating procedures for preparation of drugs relating to almost over 250 numerous medicinal plants, for example some medicinal plants were alkaloids as mandrake, poppy and henbane (Petrovska, 2012). For human survival it is very important to have a clear knowledge for the use of medicinally valued plants so it has been traditionally inherited to the generations. Plants had an abundant use for treating many ailments in the past and different books were compiled to provide the knowledge regarding information and the usage of medicinal plant in World‘s religious book named as ―Rigveda‖ and another book ―Soma‖ which served as a medicinal means. It was written by Indo-Aryans, in 4000 and 1600 B.C (Sher, 2004). Ayurveda is the medicinal indigenous system in the sub-continent of India which is known from old to 700 B.C. Ayurveda system is systemized by Sushruta and Charaka who have great attribution for citing nearly 700 plants of medicinal value. Medicinally important plants were used for different ailments. This is mentioned in the Indian old and ancient literature which provides intense help for herbal cure. Among them physostigma, digitalis and strophanthus have been used for different heart problems, quassia acts as a bitter tonic and the cinchona for malaria. ―Sushruta Samhita‖ is the name of a book which was compiled in 1000 B.C. This book consists of detailed chapters on therapeutically important herbs and herbal remedies and also includes the information for the use of such medicinal plants. Hippocrates (460 B.C.) known as a father of medicine started pharmacy. Greeks developed first ―Materia Medica‖. 500 drugs made by medicinal plants were enlisted and compiled in two bulky books named as history of plants and classes of the plants. These books were written by Jheophratus (287-370 B.C.) (Singh and Abrar, 1990). There are many references that show the narration of beneficial values of different plants like Nigella sativa and Crotalaria juncea by Our Prophet Muhammad (P.B.U.H). Hazrat Ayesha Siddiqa (R.A), wife of Muhammad (P.B.U.H) and his other associates had acknowledged of herbal remedies and are used by them for the treatment of various 2 diseases and injuries. All these show the significance and values of medicinal Plants. Additionally, herbal use of medicines was increased and it was considered as an aim in the science era of Islam (500 A.D.-1700 A.D.). For awareness of Europe countries Muslims provided the horizontal path line by the amendments of medicinal system of Greeks. Muslims also translated that entire medical task into Arabic, which was performed by Greeks and Indians. Among which opium a poppy plant has a unique significance in medicinal worth which has also been accredited with Arabs/Muslims into India (Saleem et al., 2013). In ancient times, different people used different techniques for the extraction of medicinal plants to get pharmaceutically active constituents that may serve as a source for treating different ailments. These extraction techniques may be maceration, decoction or infusion. Not only medicinally active plants get their significance in the era of pharmacy but also there is contribution of sources from animal origins too with the introduction of compound drugs in the sixteenth and eighteenth centuries. Hence people demanded such formulations which were the combination of both medicinally active plant as well as animal source. Such drugs were proved to be very effective and its extensive use was observed (Sewell and Rafieian-Kopaei, 2014). There has been a significant revival of interest in the study of natural products, which is based on the discovery of antibiotics and the importance which have been attained by some of the medicinally active constituents of plants in the treatment of cardiovascular diseases, mental disorders and certain forms of cancer. From the ancient times to present, plants have been used as a source of medicinal sources for the treatment of different ailments in all cultures throughout the world.

Traditionally, Rapanea was considered distinct from Myrsine based on the absence of well-defined filaments and style, but these characters have been shown to intergrade between species of the different genera. Pipoly (2007) and Takeuchi & Pipoly (2009) further discuss character variation in the genera in New Guinea, and formally completed the transfer of the eastern Malesian names of Rapanea to Myrsine.

All rights reserved A Taxonomic Revision of the Endemic Hawaiian Lysimachia (Primulaceae) Including Three New Species! KENDRICK L. MARR AND BRUCE A. BOHM2 ABSTRACT: A taxonomic revision of the endemic Lysimachia of the Hawaiian Islands was undertaken with the goal of clarifying species boundaries, especially within the L. hillebrandii/L. remyi complex of the previous taxonomic treatment. The endemic species appear to be monophyletic with Malesian affinities. The revision presented here is based upon observations of morphological characters. Sixteen species are recognized, of which three are probably extinct. Most species have narrow ecological preferences and are endemic to a single island. Species differ from each other most notably in the size, shape, and venation of the leaves; the size, shape, and pigmentation of the calyx and corolla lobes; and the presence or absence of viscid stems and leaves. Populations previously classified within L. hillebrandii or L. remyi differ in a number of characters not previously evaluated including vestiture, leaf color and venation, pedicel position and color, and calyx shape and color. Three new species, L. iniki, L. pendens, and L. scopulensis, are described. A key to species, species descriptions, and distribution maps are provided.

In ripe, open fruits the ball-shaped columella detaches easily and becomes a unique diaspore, which can roll on the ground.

  • Reproductive Biology of Island and Mainland Populations of Primula Mistassinica (Primulaceae) on Lake Huron Shorelines
    1819 Reproductive biology of island and mainland populations of Primula mistassinica (Primulaceae) on Lake Huron shorelines Brendon M.H. Larson and Spencer C.H. Barrett Abstract: To investigate the influence of insularity on plant reproductive biology at a local geographic scale, we examined aspects of reproduction in distylous Primula mistassinica Michx. (Primulaceae) on Lake Huron shorelines of the Bruce Peninsula and adjacent Tobermory Islands in Ontario, Canada. A total of 7 mainland and 13 nearshore island populations were compared. Controlled pollinations demonstrated that P. mistassinica possesses a dimorphic incompatibility system with intermorph crosses setting significantly more seeds than self or intramorph crosses. Floral morphology, population style-morph ratios, and seed fertility were compared in mainland and nearshore island populations to determine whether there was evidence for differences in reproductive traits between these areas. Style-morph ratios did not differ significantly from equilibrium expectations, and there were no consistent differences between island and mainland populations in floral morphology or fertility. Rather, the generalized pollination system of P. mistassinica and extensive historical opportunities for colonization appear to have mitigated insular effects so that proximate ecological factors are more relevant to the current reproductive biology of populations. Key words: distyly, insularity, pollination, reproductive biology.

MAST,2,4 DANIELLE M. S. FELLER,2,5 SYLVIA KELSO,3 AND ELENA CONTI2 2Institute of Systematic Botany, University of Zurich, Zollikerstrasse 107, 8008 Zurich, Switzerland; and 3Department of Biology, Colorado College, Colorado Springs, Colorado 80903 USA We sequenced seven cpDNA regions from 70 spp. in Dodecatheon, Primula subgenus Auriculastrum, and outgroups, reconstructed their cpDNA phylogeny with maximum parsimony, and determined branch support with bootstrap frequencies and Bayesian posterior probabilities. Strongly supported conclusions include the (1) paraphyly of Primula subgenus Auriculastrum with respect to a mono- phyletic Dodecatheon, (2) sister relationship between the North American Dodecatheon and the Californian P. suffrutescens, (3) novel basal split in Dodecatheon to produce one clade with rugose and one clade with smooth anther connectives, (4) monophyly of all sections of Primula subgenus Auriculastrum, and (5) exclusion of the enigmatic Primula section Amethystina from the similar Primula subgenus Auriculastrum. These results support the origin of the monomorphic, buzz-pollinated ¯ower of Dodecatheon from the heterostylous ¯ower of Primula. We marshal evidence to support the novel hypothesis that the solanoid ¯ower of Dodecatheon represents the ®xation of recessive alleles at the heterostyly linkage group (pin phenotype). Of the remaining traits associated with their solanoid ¯owers, we recognize at least six likely to have arisen with the origin of Dodecatheon, one that preceded it (¯ower coloration, a transfer exaptation in Dodecatheon), and one that followed it (rugose anther connectives, an adaptation to buzz pollination).

(Primulaceae) – a new vascular plant for Finland found in Turku Jussi Lampinen & Noora Metsäranta Lampinen, J., Biodiversity Unit of the University of Turku, FI-20014 Turun yliopisto, Finland. [email protected]. Metsäranta, N., Department of Biology, FI-20014 Turun yliopisto, Finland. Hottonia palustris L. is a perennial hydrophyte typically found in eutrophic, still or slowly flowing freshwater habitats, often in the presence of groundwater discharge. The species has a Eurasian distribution limited in the north by climatic and hydrological barriers: freshwater habitats in e.g. northern Scandinavia are suggested to be either too cold or too oligotrophic for the species. H. palustris has indeed hitherto remained absent in Finland and Norway, with the closest native oc- currences situated in Estonia, Denmark and Southern Sweden. In June 2019, H. palustris was found growing in a clear-watered, spring-fed and sandy-bottomed pond created by sand and gravel extraction in South-Western Finland, in the municipality of Turku. The extent of this occurrence is roughly 10 m2. We consider this the first record ofH. palustris in Finland known to have overwin- tered and flowered outside private or public gardens. In this paper, we describe the occurrence in greater detail, speculate on its origin and outline certain implications of the species’ potential pro- liferation in Finland. Concluding from the location and characteristics of the pond the species was found in, and the known dispersal syndromes the species relies on, it seems most probable that the introduction of H.
