From November 1896 to June 1897. LONDON': PRINTED FOR THE LINNEAN SOCIETY, BURLINGTON HOUSE, PICCADILLY, W., BY TATLOE AND FRANCIS, RED LION COUET, FLEET STREET. LP PROCEEDINGS OF THE LINNEiN SOCIETY OF LONDOX. (SESSION 1894-95.) November 1st, 1894. Mr. Charles Baeon Clabke, F.R.S., President, in. the Chair. The Minutes of the last Meeting were read and confirmed. Mr. Arthur Philip Grreen and Mr. Frederick Lewis were elected Fellows. At the request of the Eoyal Society of New South "Wales, the President announced the offer by that Society of a series of prizes for the best communications on cerbaiu specified subjects. Messrs. H. and J. Groves exhibited an undescribed Chara from Westmeath, and made remarks upon its peculiar mode of growth. There were exhibited for Mr. J. Gr. Otto Tepper some photo- graphs of a remarkable Fungus from South Australia, Lacco- cephalum basilapidoides, MacAlp. & Tepp., which explained the formation of the peculiar stone-like nodules occasionally found when clearing scrub-land. These were found to be due to the agglutinating nature of the mycelium of this fungus, the grains being permanently cemented by lime and ferruginous oxides. The Eev. Gr. Henslow made some remarks on a peculiar mode of propagation of Oxalis cernua observed in Malta, and exhibited some views taken during his sojourn there. Mr. Miller Christy exhibited a long piece of leaden pipe which had been gnawed through its entire length by Eats, in a manner LINN. SOC.

Bernard exhibited some photographs of Corals taken with the " Kodak " camera. A series of that remarkable Beetle Goliathus gtganteus from "West Africa was shown by Dr. E. A. Heath ; and Mr. E. M. Holmes exhibited some plants from Japan. The following papers were read : 1. " On Mediterranean and Xew Zealand Eetiporce, and a Fenestrate Bryozoan." By A. W. Waters, F.L.S. 2. " Theletiemeae et Graphideae novse." By Dr. J. Miiller, of Aargau, F.M.L.S. November loth, 1S94. Mr. Chaeles Baeon Claeke, E.E.S., President, in the Chair. The Minutes of the last Meeting were read and confirmed. Mr. J. E. S. Moore exhibited preparations illustrative of his investigations concerning the origin and nature of the achromatic spindle in the spermatocytes of Elasmobranchs. His results were approximately in agreement with those arrived at by Hermann in regard to the corresponding elements in Amphibia, and more in accord with those of I^hikawa relating to the division of jS'octiluca. As to the spindle-fibres themselves, it is supposed that during the diastral stage of the division they were the optical expression of thickenings in the wall of a membranous cylinder stretched out between the chromosomes. The Bev. G-. Henslow exhibited some curious iron implements of somewhat varied pattern used in Egypt for cutting oif the top of the Alexandrine Fig, Ficus Sgcamorus, Linn., the operatioa being necessary to render it edible by getting rid of the parasitic insect, Sycophaga crassipes, by which it is always infested. The practice was said to be very aacieut, being described by Theo- phrastus, and alluded to by the same word Kri^wv in the Septuagint version of the Old Testament (Amos, vii. 14) in translating from the Hebrew. Mr. H. jS". Bidley showed some drawings of the green larva of a Sphinx Moth mimicking a green tree-snake, Trimeresurus WagJeri, as well as a cluster of Caterpillars mimicking a fruit, all of which were found in Singapore. He also showed a drawing, from life, of the Tannin-producing Gambir-plant, Uncaria Gamhir\ in flower. —— LIKNEAN SOCIETY OF LONDOU". 3 Mr. Thomas Christy exhibited some germinating seeds of Pepper, showing the testa being carried up by the cotyledons. The following papers were read : 1. "A Revision of the British Copepoda belonging to the Grenera Bradya and Ectinosoma." By Thomas Scott, P.L.S., and Andrew Scott. 2.

The Minutes of the last Meeting were read and confirmed. Mr. Walter Tothill was elected a Pellow. Mr. E. M. Holmes exhibited and made some remarks upon a small collection of Japanese Marine Algae, some of which were of considerable rarity in European collections. Prof. D. Campbell brought forward some illustrations of the relations of vascular Cryptogams as deduced from their deve- lopment. His remarks were followed by a discussion in which Prof Bower, Dr. D. H. Scott, Mr. Carruthers, and Prof. Marshall Ward took part. The following paper was read : " A New Eevisiou of the Dipterocarpeae." By Sir Dietrich Brandis, P.E.S., P.L.S. December 20th, 1894. Mr. Chaeles Baeon Claeke, E.E.S., President, in the Chair. The Minutes of the last Meeting were read and confirmed. Mr. Peter Ewing was elected a Fellow. Mr. W. Betting Hemsley exhibited a series of specimens and figures illustrating the parasitism of Loranthus aphyllus, Miers, and other plants, from the Herbarium, Kew. Mr. J. E. Harting exhibited a specimen of a small Siberian Warbler, Phylloscopus superciliosus, which had been obtained near Beverley, Yorkshire, in October last, and made some remarks upon its haunts, habits, and migration, and upon the previous instances which had been noted of its accidental occur- rence in the British Islands. 12 ——, PEOCEEDIirGS OF THE The following papers were read : 1. " On the Spinning-Glands of Fhri/nus." By Henry Meyners Bernard, F.L.S. 2. " Contributions to the Knowledge of Monocotyledonous Saprophytes." By Percy Groom, F.L.S. January 17th, 1895.

Mr. Stephen Trovte Dunn, Mr. James Peter Hill, Mr. "Robert Okell, Mr. William Burne Stonham, Surg.-Capt. John Henry TuU Walsh, and Mr. James Wilshire were elected Fellows. Mr. George Murray exhibited lantern-slides representing a new part of PacJiytheca, consisting of a cup-shaped receptacle in which Pacliytheca was fouud by Mr. John Storrie of CardiflF, The walls of the cup are composed of radiating chambers like those of AcetabuJaria, and in the centre there are traces of an axile structure. Mr. Murray considered that this discovery only made the interpretation of the nature oiPachytheca more difficult than ever. Mr. Arthur Lister exhibited and made remarks upon a Land-Bail, Crex pratensis, which had been found a few days pre- viously near Axminster in Devonshire, where it had been killed by coming in contact with telegraph-wires. The occurrence in midwinter of a bird which is a summer visitor to this country seemed to him to be worth notice. Mr. J. E. Harting exhibited specimens of northern sea-birds which had been driven upon the East Coast of England during recent gales : amongst -others the Little Auk, Mergulus alle, of which great numbers had come ashore dead or in an exhausted condition ; the Little Gull, Larusminutus, obtained at Whitstable on January 5th; and an example of Briinnich's Guillemot, Uria Brunnichii, Sabine (Trans. Linn. Soc. xii. p. 538), a species which, though abundant in Greenland, North-east Iceland, and Spitzbergen, is of such extremely rare occurrence on our coasts, that not more than two or three authenticated instances of its appearance here have been recorded.

Ecological influences in the biogeography of the aus- tral sedges. MSc dissertation. University of Cape Town. Cape Town. February 2016. supervisors: A. Muthama Muasya G. Anthony Verboom ABSTRACT The biogeographic history of a species is a result of both stochastic processes such as dispersal and habitat filters that determine where a population with a given set of biological requirements can become es- tablished. In this dissertation, I examine the geographical and ecolog- ical distribution of the sedge tribe Schoeneae in conjunction with its inferred speciation history in order to determine the pattern of disper- sal and the environmental factors that have influenced establishment. The biogeographic reconstruction indicates numerous transoceanic dispersal events consistent with random diffusion from an Australian point of origin, but with a bias towards habitats with vegetation type and moisture regime similar to the ancestral conditions of the given subgroup (open and dry habitats in the majority of cases). The global distribution of the tribe also suggests a preference for low-nutrient soils, which I investigate at the local (microhabitat) scale by contrast- ing the distributions of the tribes Schoeneae and Cypereae on the Cape Peninsula along soil fertility axes.

Abstract Fruit of Sararanga sinousa Hemsley is called as “Anggur Papua” or “grape Papua” by local people. S. sinousa is endemic to Papua and its fruits are classified as berries. Morphometric characteristic (weight and diameter), nutritional values: namely proximate composition, soluble solids content, titratable acidity, pH, pectin, ascorbic acid and analysis of antioxidant activity (DPPH assay) of the fruits at three different ripening stages were determined. The weight and diameter of S. sinousa fruit did not differ at different ripening stage viz. At greenish-white, orange-red and red fruit stages. The nutritional value of S. sinousa fruit showed that proteins content, fat and pH remained unchanged as colour of fruit developed from greenish-white to orange-red and red. However, total carbohydrates, soluble solids content, ratio of soluble solids content: titratable acidity, pectin and ascorbic acid were increased significantly, despite the decrease of TA.

  • Moneywort Lysimachia Nummularia L
    Weed of the Week Moneywort Lysimachia nummularia L. Common Names: moneywort, creeping Jenny, creeping Charlie, creeping Joan, running Jenny, wandering Jenny, wandering sailor Native Origin: Introduced from Europe and southwest Asia for horticulture as an ornamental ground cover. Description: An herbaceous, low-growing, perennial plant in the primrose family (Primulaceae), with evergreen to semi-evergreen foliage. The smooth creeping stems can grow up to 2 feet long and 2-4 inches in height and branch frequently to form a mat-like growth. Leaves are opposite, simple and broadly ovate ¼ to 1 ½ inches long. The broadly oval leaves, which are obtuse at both ends, resemble small coins and give the plant its name. The flowers are solitary in the leaf axils and have pedicels that are about the same length as the leaves. They are yellow with small dark red spots, blooming from June to August, but often do not flower at all. The small seeds are borne in capsular fruits that are roughly as long as its sepals. In riparian areas, seeds are likely dispersed by flood waters. The extent to which seeds are dispersed by animals is not fully known, but some transport seems likely. It is also spreads vegetatively by creeping stems. Habitat: It can be found in a variety of different habitat types; however, it grows most vigorously and poses the biggest threat in moist areas such as wet meadows, swamps, floodplain forests, stream banks, bottoms, ditches, roadsides and along the banks of small water bodies. It prefers moist, rich, shaded soils. Distribution: It is found throughout the eastern United States with the exception of Florida.

Complete Peer review History: http://www.sciencedomain.org/review-history/23116 Received 24th November 2017 th Original Research Article Accepted 6 February 2018 Published 10th February 2018 ABSTRACT I report an unexpected negative covariance occurring between two major parameters governing shell growth in marine bivalves, especially within the order Veneroida. This relationship is highlighted, here, considering a set of forty, rather common species of clams collected from French coasts. Interestingly, this negative covariance has two (geometrically related) consequences on the pattern of variation of shell shape at the inter-specific level: (i) An extended range of variation of shell elongation ‘E’ is made compatible with. (ii) A severely restricted range of variation of the ventral convexity ‘K’ of the shell contour. I suggest that: (i) The extended range of interspecific variation of the shell elongation ‘E’ results from a trend towards larger differentiation between species according to this functionally important parameter E, while, in contrast, (ii) The strongly restricted range of variation of the ventral convexity ‘K’ of the shell contour might arguably result from a common need for improved shell resistance, face to mechanical solicitations from the environment, either biotic or abiotic.

Lecce-Monteroni 73100 Lecce RESEARCH ARTICLE ITALY Abstract 1 - Lagoons are ecotones between freshwater, marine and terrestrial biotopes, characterized by internal ecosystem heterogeneity, due to patchy spatial and temporal distribution of biotic and abiotic components, and inter-ecosystem heterogeneity, due to the various terrestrial-freshwater and freshwater-marine interfaces. 2 - Here, we carried out an analysis of environmental heterogeneity and benthic macro-invertebrate guilds in a sample of 26 Italian lagoons based on literature produced over a 25 year period.. 3 - In all, 944 taxonomic units, belonging to 13 phyla, 106 orders and 343 families, were recorded. Most species had a very restricted geographic distribution range. 75% of the macroinvertebrate taxa were observed in less than three of the twenty-six lagoons considered. 4 - Similarity among macroinvertebrate guilds in lagoon ecosystems was remarkably low, ranging from 10.5%±7.5% to 34.2%±14.4% depending on the level of taxonomic resolution. 5 - Taxonomic heterogeneity was due to both differences in species richness and to differences in species composition: width of seaward outlet, lagoon surface area and water salinity were the most important factors affecting species richness, together accounting for up to 75% of observed inter-lagoon heterogeneity, while distance between lagoons was the most significant factor affecting similarity of species composition.

The Society works through a network of partnerships in the scientific community. In an era of specialisation the Society promotes the transfer of information across disciplinary boundaries. It collaborates with government and international organisations to highlight the urgency and magnitude of the task of documenting the world’s flora and fauna. The Linnean Society was founded in 1788 for ‘the cultivation of the Science of Natural History in all its branches’. The Society is named after the great 18th Century Swedish naturalist, Carl Linnaeus (1707 - 1778), who created the binomial system of biological classification now used throughout the world. The Society acquired Linnaeus’s collection of plant and animal specimens, and his books and letters, from its first President, James Edward Smith. The Society has been at the heart of many scientific and cultural developments relating to our understanding of the natural world. Most notably, Charles Darwin’s and Alfred Russell Wallace’s epoch-making papers on evolution by natural selection were first read at a meeting of the Society. The Society is proud of its past, but is equally enthusiastic about its future. Today it encourages discussion and research by: ♦ publishing three leading international journals on biology, botany and zoology.
