Sterk P. de Vlaming** and A.C. Bolsman-Louwen* * ** Hugo de Vries-Laboratorium, Genetisch Instituut, Universiteit van Amsterdam Anthyllis vulnerariashows an appreciable variation in the colour of the corolla which ranges from pale yellow to a deep purplish red. Also the calyx often has purple teeth. Most of the subspecies of A. vulneraria (16 out of 24) occur in the Medi- in the N. and About the terranean area, more particularly W. parts. moiety of these subspecies has purple or reddish flowers; the other halfpredominantly central with yellow or yellowish ones. In Europe 4 subspecies yellow corollas variants In N. also 4 found occur; red-flowered are rare. Europe subspecies are red-flowered vulneraria vulneraria of which one has a variety: A. ssp. var. coccinea (Cullen 1968). The red floral colour is predominantly found in the Mediterraneanarea. According to Becker (1912) the red-floweredpopulations are mostly encountered in drierand warmer climates; the yellow-flowered ones being more dominantin the colderand moister regions. the of corolla Observations by Couberc (1971) suggest that pigmentation the is strongly influenced by environmental conditions and certainly does not always provide a reliable taxonomic characteristic. The anthocyanin pigments of Anthyllis had not been studied previously. The flavonols have been inves- tigated by Gonnet & Jay (1972). In this study flowers of 12 populations of A. vulneraria were studied and flowers of one population of A. montana. The results are shown in the table.

Introduction There are approximately 700 identified species of carnivorous plants placed in 15 genera of nine families of dicotyledonous plants (Albert et al. 1992; Ellison & Gotellli 2001; Fleischmann 2012; Rice 2006) (Table 1). In India, a total of five genera of carnivorous plants are reported with 44 species; viz. Utricularia (38 species), Drosera (3), Nepenthes (1), Pinguicula (1), and Aldrovanda (1) (Santapau & Henry 1976; Anonymous 1988; Singh & Sanjappa 2011; Zaman et al. 2011; Kamble et al. 2012). Inter- estingly, northeastern India is the home of all five insectivorous genera, namely Nepenthes (com- monly known as tropical pitcher plant), Drosera (sundew), Utricularia (bladderwort), Aldrovanda (waterwheel plant), and Pinguicula (butterwort) with a total of 21 species. The area also hosts the “ancestral false carnivorous” plant Plumbago zelayanica, often known as murderous plant. Climate Lowland to mid-altitude areas are characterized by subtropical climate (Table 2) with maximum temperatures and maximum precipitation (monsoon) in summer, i.e., May to September (in some places the highest temperatures are reached already in April), and average temperatures usually not dropping below 0°C in winter.

As a consequence of relying on non-renewable energy sources and reckless encroachment on natural habitats a lot of plant and animal species have become extinct and more and more species are getting endangered. Thus celebrating biodiversity and solidarity for all life forms, from the tiniest one to the most complex eco-systems, has been in the centre of our attention and operational activities. Keywords: durable development, ecology, endangered species. 1. Introduction Within the massive destruction of forests and forest climate, we witness significant changes, Just as the man has passed from the stage of sometimes radical of the environment. For the animal hunter and collector up to animal raiser and farmer, and plants which have survived through a long period the natural vegetation has increasingly been subject of adaptation, a new difficult era starts again.

The diversity of wild orchids in the southern slope of Mount Merapi, Yogyakarta, Indonesia eight years after the 2010 eruption. Biodiversitas 21: 4457-4465. The ecosystem of the slopes of Mount Merapi is mountain tropical forest which is frequently affected by volcanic activities. The dynamics of the volcano affect the diversity and abundance of orchids in the ecosystem. Tritis is an area included in the Turgo Hill of the southern slope of Mount Merapi and is under the management of Mount Merapi National Park. The ecosystem in Tritis area classified as lower mountain forest and it has been affected by Mount Merapi eruption. This study aimed to do an inventory of orchid species in Tritis to know the diversity and abundance of orchids that exist in this area.

  • Bergia Texana (Hook.) Seub
    Bergia texana (Hook.) Seub. Ex Walp. Bergia texana Texas bergia Texas bergia Elatinaceae (Waterwort Family) Status: State Review Group 1 Rank: G5SNR General Description: Adapted from Hitchcock et al. (1961), and Hickman (1993): Bergia texana is an annual or short-lived perennial with simple to freely branched, trailing to ascending stems 2 to 12 in. Illustration by F. Emil. (0.5-3 dm) long and a somewhat woody base when perennial. The from Britton, N.L., and A. plant is covered in very short hairs except on the petals. The leaves Brown. 1913. An Illustrated are 4-ranked, ¾ to 1 ½ in. (2-4 cm) long, and have a wedge-shaped Flora of the Northern United base and a pointed tip. The leaves have a fine-toothed margin and a States and Canada. Vol. 2 slender petiole. The flowers occur along the stem in leaf axils as well as at the tip, and are either solitary or in clusters. The flowers are white to greenish and have 5 oblong petals that are shorter than the toothed leafy bracts beneath them, which are about 1/8 in. (3 mm) long. Many of the flowers do not open and self-pollinate. The fruit is ovoid with 5 chambers, each many-seeded. The oblong seeds are not visible through the fruit wall, and are somewhat curved, brown, and net-like. Identification Tips: This is the only species of Bergia in the US. Other members of the Waterwort Family that are found in Wash- ington include Elatine brachysperma, E. californica, and E. rubella. Bergia texana may be distinguished from the Elatine species by its woody base, the number of petals in the flower, and the visibility of the seeds through the fruit wall.

  • Botrychium Lunaria
    Botrychium lunaria Family: Ophioglossaceae Genus: Botrychium Subgenus: Botrychium (syn. Eubotrychium) Species: Botrychium lunaria (L.) Swartz Common Name: Common Moonwort Ploidy: Diploid Published description: Trophophore stalk 0- 1 mm; blade dark green, oblong, 1-pinnate, to 10 x 4 cm, thick, fleshy. Pinnae to 9 pairs, spreading, mostly overlapping except in shaded forest forms, distance between 1st and 2nd pinnae not or slightly more than between 2nd and 3rd pairs, basal pinna pair approximately equal in size and cutting to adjacent pair, broadly fan-shaped, undivided to tip, margins mainly entire or undulate, rarely dentate, apical lobe usually cuneate to spatulate, notched, approximate to adjacent lobes, apex rounded, venation like ribs of fan, midribs absent. Sporophores 1-2 pinnate, 0.8- 2 times length of trophophore. 2n = 90. (Wagner and Wagner 1993) Identification Botrychium lunaria is most easily differentiated from other moonworts by the breadth of its pinnae. Typically the basal pinnae span an arc of nearly 180 degrees and the third pinna pair has a span of approximately 90 degrees. The upper pinnae angle upward—the lower side margin creates a large angle (nearly 90°) with the rachis, the upper side margin is nearly parallel to the rachis. Although it is occasionally short stalked, the trophophore of B. lunaria is typically sessile, the stalk length seldom equaling or exceeding the distance between the first pinna pair as it usually does in B. minganense. Plants are green to dark green with a surface that is lustrous to dull, but never glaucous. The sporophore is long stalked, the stalk, at spore release, exceeding the length of the trophophore.

  • Botrychium Lunaria (L.) Sw
    New England Plant Conservation Program Botrychium lunaria (L.) Sw. Moonwort Conservation and Research Plan for New England Prepared by: Arthur V. Gilman Marshfield, Vermont For: New England Wild Flower Society 180 Hemenway Road Framingham, MA 01701 508/877-7630 e-mail: [email protected] • website: www.newfs.org Approved, Regional Advisory Council, 2003 1 SUMMARY _____________________________________________________________ Moonwort (Botrychium lunaria (L.) Sw.) is a rare fern in the Ophioglossaceae. It occurs in a very few locales in northern New England, where it is at the southern edge of its range. The reasons for its rarity are not well understood, but it appears to have always been very rare in the region and does not appear to have suffered declines due to land-use practices. The species is a poor competitor and its habitats are typically small patches (tens to hundreds of square feet) where some soil disturbance has occurred or where other factors prevent dense turf or thick duff layers from occurring. Such habitats occur in maritime grasslands along the coast of eastern Maine, in northern white cedar forests in northern Maine, and possibly on forested hilltop areas in southeastern Vermont. Calcareous soils, whether derived from bedrock, calcareous till deposits, or from ongoing calcium deposition from ocean debris (i.e., mussel shells) or sea-spray are required for this species. Four current (within the past 20 years) sites are known only in Maine, of which two are confirmed as this species. Although no vouchers have been seen for the other two current Maine sites, they are presumed to be of Botrychium lunaria.
