Autumn Plants of the Peloponnese
Autumn Plants of the Peloponnese Naturetrek Tour Report 24 - 31 October 2018 Crocus goulimyi Chelmos Mystras Galanthus reginae-olgae Report& images by David Tattersfield Naturetrek Mingledown Barn Wolf's Lane Chawton Alton Hampshire GU34 3HJ UK T: +44 (0)1962 733051 E: [email protected] W: www.naturetrek.co.uk Tour Report Autumn Plants of the Peloponnese Tour participants: David Tattersfield (leader) and seven clients Day 1 Wednesday 24th October We made rapid progress along the motorway and stopped at Corinth to view the canal, which effectively makes the Peloponnese an island. Here we found our first flowers, the extremely common Autumn Squill Prospero autumnale, the striped, hooded spathes of Friar’s Cowl Arisarum vulgare, and a number of Crocus mazziaricus. A few butterflies included Long-tailed Blue, Lang’s Short-tailed Blue, Eastern Bath White, Mallow Skipper and a Pigmy Skipper. We continued along the newly-completed coast road, before turning inland and climbing steeply into the mountains. We arrived in Kalavrita around 6pm and after settling in to our hotel, we enjoyed a delicious meal of home-cooked food at a nearby taverna. Day 2 Thursday 25th October We awoke to a sunny day with cloud over the mountains. Above Kalavrita, we explored an area of Kermes Oak scrub and open pasture, where we found more white Crocus mazziaricus and Crocus melantherus. Crocus melantherus, as its name suggests can be distinguished from other autumn-flowering species by its black anthers and purple feathering on the outer tepals. Cyclamen hederifolium was common under the shade of the trees. -

Ker-Gawl. ex Accepted : June 15, 2021 Spreng. and Allium stylosum O.Schwarz were investigated. In order to determine the anthelmintic activity, the time elapsed for the duration of paralysis and death was Keywords determined after the extracts of different concentrations (10, 20 and 30 mg/mL) were added to the Tubifex tubifex in petri dishes. Each concentration of A. stylosum aerial Ornithogalum nutans, and underground parts extracts showed high anthelmintic activity. In addition, aerial Sternbergia lutea, extract of O. nutans at a concentration of 30 mg/mL showed high anthelmintic Allium stylosum, activity. A. stylosum extracts showed a higher activity than the standard anthelmintic Artemia salina, drug. The toxic activity was determined against Artemia salina with brine shrimp Anthelmintic activity lethality test. Among all extracts, the underground extract of S. lutea showed the highest activity with 0.002 mg/mL, LC50, the aerial extract of O. nutans showed the lowest activity with 0.03 mg/mL, LC50. -

Vegetation Survey of Mount Gorongosa
VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 VEGETATION SURVEY OF MOUNT GORONGOSA Tom Müller, Anthony Mapaura, Bart Wursten, Christopher Chapano, Petra Ballings & Robin Wild 2008 (published 2012) Occasional Publications in Biodiversity No. 23 Biodiversity Foundation for Africa P.O. Box FM730, Famona, Bulawayo, Zimbabwe Vegetation Survey of Mt Gorongosa, page 2 SUMMARY Mount Gorongosa is a large inselberg almost 700 sq. km in extent in central Mozambique. With a vertical relief of between 900 and 1400 m above the surrounding plain, the highest point is at 1863 m. The mountain consists of a Lower Zone (mainly below 1100 m altitude) containing settlements and over which the natural vegetation cover has been strongly modified by people, and an Upper Zone in which much of the natural vegetation is still well preserved. Both zones are very important to the hydrology of surrounding areas. Immediately adjacent to the mountain lies Gorongosa National Park, one of Mozambique's main conservation areas. A key issue in recent years has been whether and how to incorporate the upper parts of Mount Gorongosa above 700 m altitude into the existing National Park, which is primarily lowland. [These areas were eventually incorporated into the National Park in 2010.] In recent years the unique biodiversity and scenic beauty of Mount Gorongosa have come under severe threat from the destruction of natural vegetation. This is particularly acute as regards moist evergreen forest, the loss of which has accelerated to alarming proportions. -
A Morphometric Study of Species Delimitation in Sternbergia Lutea (Alliaceae, Amaryllidoideae) and Its Allies S
Botanical Journal of the Linnean Society, 2008, 158, 460–469. With 5 figures A morphometric study of species delimitation in Sternbergia lutea (Alliaceae, Amaryllidoideae) and its allies S. sicula and S. greuteriana EWAN GAGE1,2 and PAUL WILKIN2* FLS 1Plant Science Laboratories, The University of Reading, Whiteknights, Reading, Berkshire RG6 6AS, UK 2Royal Botanic Gardens, Kew, Richmond, Surrey TW9 3AB, UK Received 22 October 2007; accepted for publication 13 May 2008 The morphological chararacters used to differentiate the species Sternbergia lutea (L.) Ker Gawl. ex Spreng., Sternbergia sicula Tineo ex Guss. and Sternbergia greuteriana Kamari & R.Artelari were found not to possess discrete or consistently different states during an attempt to produce an electronic multi-access key to the genus. Thus, variation in floral and leaf morphology in the three species was further explored to re-evaluate taxon limits using herbarium specimens and statistical methods, including principal components analysis (PCA) and elliptic Fourier analysis (EFA). This confirmed that variation was continuous between the three species. Sternbergia sicula and S. greuteriana are sunk into S. lutea and a revised description provided. It is suggested that cultivar status is the most appropriate rank for the cultivated forms of the S. lutea complex. © 2008 The Linnean Society of London, Botanical Journal of the Linnean Society, 2008, 158, 460–469.

Srgc Bulb Log Diary
SRGC ----- Bulb Log Diary ----- ISSN 2514-6114 Pictures and text © Ian Young BULB LOG 40................................4th October 2017 Rhododendron leaves Nothing is more characteristic of autumn than the leaves as they turn yellow, red and bright orange often with splashes of green still visible when you view them against the light as captured in the cover image of Hamamelis leaves. Photographed into the sun, exposed to retain the deep blue skies and using a small aperture which achieves the star effect of the sun. Shafts of light from the low sun passing through the trees and shrubs greatly adds to the drama of the season by picking out and highlighting colours creating striking effects of light and shade. Rhododendron leaves(above) also take on autumn colours as they come towards the end of their life then fall off – it is just that instead of lasting for a single growing season each Rhododendron leaf can last one or two years before it is shed so the shrub is never without leaves. There are some Rhododendrons that are deciduous, losing all their leaves every year, most of these are what we used to know as Azalea before they were sunk into Rhododendron. Crocus have a habit of getting everywhere in our garden as you may notice in this picture where a lone Crocus nudiflorus has made its way into the bonsai pot. The spotlight effect of a shaft of sunlight picks out Colchicum agrippinum and Crocus speciosus flowers growing through the fine foliage of Geranium robertianum with further colourful highlights provided by the leaves fallen from the Hamamelis, seen above and on the cover. -

Study of Stomata in Some Species of Alocasia and Syngonium of Family Araceae Juss
www.ijapbc.com IJAPBC – Vol. 5(2), Apr - Jun, 2016 ISSN: 2277 - 4688 INTERNATIONAL JOURNAL OF ADVANCES IN PHARMACY, BIOLOGY AND CHEMISTRY Research Article Study of Stomata in some species of Alocasia and Syngonium of family Araceae juss. Meenakshi Vaidya S.V.K.M’s Mithibai College, Vile-Parle West, Mumbai 400056 ABSTRACT Araceae, a tropical family consisting of 109 genera and about 2,239 species. Plants are mostly herbaceous, habit rarely aquatic. Rootstock is rhizomatous or tuberous or cornous. Leaves are simple or compound, parallel or net veined. Laticifers are common. Silica bodies lacking, oxalate raphides present. Inflorescence is simple spadix with a spathe. Flowers are minute, sessile bisexual or more commonly unisexual with reduced perianth or without perianth. Stamens are six in a flower. Carpels are three, syncarpous. Ovules one - many on axile or parietal or basal or peudulous placenta. Fruit is berry. There are several genera belonging to Araceae whose taxonomic position is not clear. Stomata in Dieffenbachia, Scindapsus, Arisaema, Lysichiton and few species of Araceae stated that family is characterised by possession of 4 or more than 4 subsidiary cells in majority of its members representing the primitive status of the family within monocotyledons. So, stomatal complexes study in two genera and 11 species was undertaken in the present work to understand the taxonomic position of these members of Araceae and also to determine taxonomic utility of anatomical characters. Key words: Alocasia, Syngonium, paracytic, amphibrachyparacytic, brachyparatetracyctic, paratetracytic, cyclocytic, and brachyparacytic. INTRODUCTION Engler1 determined that if Araceae were to be Maharashtra. The details are as follows. The classified as a natural group, flower structure aloone arrangement of species is followed as recognized by was insufficient. -
Syngonium Podophyllum1
Fact Sheet FPS-566 October, 1999 Syngonium podophyllum1 Edward F. Gilman2 Introduction This rapidly-growing evergreen vine produces a multitude of variegated, bright green, arrow-shaped leaves on climbing and trailing stems (Fig. 1). If allowed to climb, Nephthytis develops large tropical leaves and wrist-thick stems. When kept from climbing, it quickly provides a green mat of six-inch high foliage, creating an excellent groundcover. It can become weedy, much the same as English ivy does, and will require regular trimming along the edges of the bed. It will also grow up into shrubs and look messy so it is best located in front of a shrub area, or out by itself in the landscape. General Information Scientific name: Syngonium podophyllum Pronunciation: sin-GO-nee-um poe-doe-FILL-lum Common name(s): Syngonium, Nephthytis Family: Araceae Plant type: ground cover; herbaceous USDA hardiness zones: 10B through 11 (Fig. 2) Planting month for zone 10 and 11: year round Figure 1. Syngonium. Origin: native to North America Uses: mass planting; container or above-ground planter; suitable for growing indoors; hanging basket; cascading down Description a wall Height: depends upon supporting structure Availablity: generally available in many areas within its Spread: depends upon supporting structure hardiness range Plant habit: prostrate (flat) Plant density: moderate Growth rate: fast Texture: medium 1.This document is Fact Sheet FPS-566, one of a series of the Environmental Horticulture Department, Florida Cooperative Extension Service, Institute of Food and Agricultural Sciences, University of Florida.
