Mycosphere 10(1), 310–489, Doi 10.5943/mycosphere/10/1/7 Abstract Leotiomycetes is regarded as the inoperculate class of discomycetes within the phylum Ascomycota. Taxa are mainly characterized by asci with a simple pore blueing in Melzer’s reagent, although some taxa have lost this character. The monophyly of this class has been verified in several recent molecular studies. However, circumscription of the orders, families and generic level delimitation are still unsettled. This paper provides a modified backbone tree for the class Leotiomycetes based on phylogenetic analysis of combined ITS, LSU, SSU, TEF, and RPB2 loci. In the phylogenetic analysis, Leotiomycetes separates into 19 clades, which can be recognized as orders and order-level clades.

Linnaeus' Philosophia Botanica
linnaeus’ Philosophia Botanica STEPHEN FREER Stephen Freer, born at Little Compton in1920, was a classical scholar at Eton and Trinity College Cambridge. In 1940, he was approached by the Foreign Office and worked at Bletchley Park and in London. Later, Stephen was employed by the Historical Manuscripts Commission, retiring in 1962 due to ill health. He has continued to work since then, first as a volunteer for the MSS department of the Bodleian Library with Dr William Hassall, and then on a part-time basis at the Oxfordshire County Record. In 1988, he was admitted as a lay reader in the Diocese of Oxford. His previous book was a translation of Wharton’s Adenographia, published by OUP in 1996. A fellow of the Linneau Society of London, Stephen lives with his wife Frederica in Gloucestershire. They have a daughter, Isabel. COVER ILLUSTRATION Rosemary Wise, who designed and painted the garland of flowers on the book cover, is the botanical illustrator in the Department of Plant Sciences in the University of Oxford, associate staff at the Royal Botanic Gardens, Kew, and a fellow of the Linneau Society of London. In1932 Carl Linnaeus made an epic journey to Lapland, the vast area across arctic Norway, Sweden, and Finland. In 1988, to mark the bicentenary of the Linneau Society of London, a group from Great Britain and Sweden retraced his route. Rosemary, was the official artist and the flowers featured here are taken from ones painted at that time, plants with which Linnaeus would have been familiar. The garland of flowers surrounds an image of the medallion portrait of Linnaeus by C.

Phylogeny of Hedychium and Related Genera (Zingiberaceae)Basedonits Sequence Data
EDINB. J. BOT. 57 (2): 261–270 (2000) 261 PHYLOGENY OF HEDYCHIUM AND RELATED GENERA (ZINGIBERACEAE)BASEDONITS SEQUENCE DATA T. H. WOOD*, W. M. WHITTEN† & N. H. WILLIAMS‡ The phylogeny of Hedychium J. Koenig was estimated using sequence data of internal transcribed spacer regions 1 and 2 (ITS1, ITS2) and 5.8S nuclear ribosomal DNA. Sequences were determined for 29 taxa, one interspecific hybrid of Hedychium and one species in each of 16 other genera of Zingiberaceae representing tribes Hedychieae, Globbeae, Zingibereae and Alpinieae. Cladistic analysis of these data strongly supports the monophyly of Hedychium, but relationships to other genera are poorly supported. Within Hedychium, four major clades are moderately supported. These clades are also distinguishable on the basis of number of flowers per bract and distribution. Stahlianthus, Curcuma, and Hitchenia also form a strongly supported clade. Based on this limited sample, the currently defined tribes of Zingiberoideae are not monophyletic. The Asiatic genera form a monophyletic group within this broadly defined Hedychieae. The taxonomy and biogeography of Hedychium are reviewed. Keywords. Biogeography, ginger, Hedychium, ITS, phylogeny, Zingiberaceae. INTRODUCTION Within the Zingiberaceae four tribes are currently accepted (Smith, 1981): Globbeae (bow-shaped filament with unilocular ovary with parietal placentation; four genera); Zingibereae (pointed anther crest surrounding the style and staminodal lobes adnate to the labellum; one genus, Zingiber); Hedychieae (plane of leaf distichy parallel to the rhizome, lateral staminodes petaloid and free from the lip except in Siphonochilus and Curcumorpha, ovary trilocular with axile placentation or unilocular with basal or free columnar placentation; 21 genera); and Alpinieae (distichy of leaves perpen- dicular to the rhizome, lateral staminodes reduced to teeth or swellings or absent, ovary trilocular with axile placentation; 22 genera).

Plant Morphology-II (Flower, Fruit, Seed, Family)
13 Plant Morphology-II (Flower, Fruit, Seed, Family) · Inflorescence : Arrangement of flowers on rachis (axis) is called Anthotaxy or Inflorescence. It has two types : (A) Racemose : Apical bud is not transformed into flower and flowers formed in acropetal succession. It has 6 types. (A-i) Raceme : Stalked flowers on axis. e.g., Mustard and caesalpinia (A-ii) Spike : Sessile flowers on axis. e.g., Achyranthus (A-iii) Spadix : Flowers bearing axis becomes fleshy. Male flowers on upperside and female flowers remain lowerside. Between male and female flowers, sterile flowers are present. Whole inflorescence in protected by foliage bract, i.e. spathe. e.g., Colocasia, Musa. (A-iv) Catkin : Unisexual flowers on pendulous axis of spike. e.g., Mulberry, Acalypha. (A-v) Umbel : Rachis becomes condensed and stalked flowers are arranged on it like umbrella. The whorl of bracts is called involucre. e.g., Onion, Fennel. (A-vi) Capitulum : Peduncle becomes disc like and flat. It is called receptacle. Flowers are centripetally arranged. Peripheral flowers and central flowers are known as ray florets and disc florests respectively. Like Umbel, it also has involucre. e.g., Sunflowers and Tagetes. (B) Cymose : Apical bud transforms info flowers. (B-i) Cymose solitary : Only one flower is present at the tip of axis. e.g., Hibiscus, Argemone. (Note : There is clear cut demarcation between axis of inflorescence and peduncle.) (B-ii) Uniparous (Monochasial) : The main axis ends in a flower and growth continued by a single lateral branch. It has two types. (B-ii-a) Helicoid : Apical bud gives rise to a single lateral branch before being transformed into flowers.

Exercise 11 Aim: Study and describe flowering plants of families Solanaceae, Fabaceae and Liliaceae. Principle: Taxonomy deals with identification, nomenclature and classification of organisms. Bentham and Hooker's system of classification is universally used for classification of plants. Field identification of plants is based primarily on morphological features particularly the floral characters. Requirement: Locally available plant specimens of Solanaceae, Fabaceae and Liliaceae. (minimum 3 species for each family other than the ones described for reference in the manual); each specimen should have at least a small branch with a few inter nodes, leaves, flowers and fruits; glass slides, cover glass, water, 100 ml beakers, petridish, razor, blade, needles, brush, hand lens, dissecting microscope and compound microscope. Procedure Keep the twigs in beakers containing water. Make yourself familiar with the terms given to describe the habit of plant, its root system, stem and leaf, inflorescence and flowers. Describe the vegetative and floral features of the plant in the same sequence using terms described therein. Observe the flower bud under dissection microscope or a hand lens and note the aestivation patterns of calyx and corolla,© numberNCERT of sepals and petals (tri, tetra, penta- merous), number of stamens. Cut LS of the flower, place it on a slide and observe under the dissecting microscope to study: • Position (attachment) of stamens – opposite/alternate to petals; free or epipetalous; extrorse/ introrse anthers (anther lobes in the bud face away from axis – extrorse; anther lobes in the bud face towards the main axis – introrse). • Number of carpels (mono, bi, tri- carpellary); Position of the ovary (epigynous, perigynous, hypogynous).

Chlorophytum Borivilianum (Safed Musli): a Review
Phcog Rev. Vol, 3, Issue 5, 154-169, 2009 Available Online : www.phcogrev.com PHCOG REV. : Review Article Chlorophytum borivilianum (Safed musli): A Review Nikam Vijaya K.* and Prakash D. Chavan Department of Botany, Shivaji University, Kolhapur – 416 004 (MS) India. *corresponding author : [email protected] ABSTRACT Chlorophytum borivilianum Sant. and Fernand. belongs to family Liliaceae, is a promising medicinal plant with great economic potential. Appreciation of medicinal value of safed musli tubers has been made in ancient Indian medicine literature right from 11 th century A.D. The tubers contain saponins and are aphrodisiac, adaptogenic, antiageing, health restorative and health promoting. The plant is cultivated in different parts of India on a small scale at present. However, systematic information on different aspects of this species is not available. In this review, an attempt has been made to present this information. A. About the genus Chlorophytum Amongst the species used as Safed musli, C. arundinaceum is Genus Chlorophytum earlier included in family Liliaceae has specifically reputed for the tuber quality in the Ayurvedic text been recently kept in family Anthericaceae of series (5). However, at present, C. borivilianum has been paid greater Coronariae in the class Monocotyledons (1). The name attention and regarded as a main Safed musli crop by several Chlorophytum is derived from Greek word, Chloros meaning workers (5, 22-24). green and phyton meaning plant (2). Hooker and Jackson (3), in B. Botany Index Kewensis have listed more than 300 species of the Santapau and Fernandes collected the specimens of a new genus Chlorophytum and suggested that its probable centre of species of Chlorophytum on 14 th June 1954 in the plains and origin and diversification lies in tropical and subtropical lower slopes of the Krishnagiri National Park Salsette Island, Africa, where 85% of the species are found.
