Notes on Fraxinus Profunda (Oleaceae)
Nesom, G.L. 2010. Notes on Fraxinus profunda (Oleaceae). Phytoneuron 2010-32: 1–6. Mailed 10 August 2010. NOTES ON FRAXINUS PROFUNDA (OLEACEAE) Guy L. Nesom 2925 Hartwood Drive Fort Worth, TX 76109, USA www.guynesom.com ABSTRACT A taxonomic overview is provided for Fraxinus profunda –– including a nomenclatural summary with lectotypes designated for F. profunda and the synonymous F. michauxii , an updated morphological description including a comparison with F. pennsylvanica , and a county-level distribution map. Geographically disjunct records for F. profunda in distinctly inland localities (Mississippi and Alabama) are documented; far-inland records from Tennessee and North Carolina were based on collections of F. biltmoreana . KEY WORDS : Fraxinus profunda , F. michauxii , F. pennsylvanica , Oleaceae Fraxinus profunda occurs primarily along the Atlantic and Gulf coasts into peninsular Florida and in drainages of the Mississippi River and in the Ohio River basin (Little 1977; McCormac et al. 1995). At the northwestern corner of its range, it occurs in bottomlands of the Kankakee River (vPlants 2010), an Illinois/Mississippi River tributary. Limits of the northern range of the species (Michigan, Ontario) have recently been documented in detail (McCormac et al. 1995; Waldron et al. 1996). The trees consistently grow in river swamps and floodplains, especially those seasonally inundated, freshwater tidal wetlands, commonly with bald cypress, swamp cottonwood, and water tupelo. In Illinois, Indiana, Ohio, and northward, they often are found in wet woods and swampy depressions in upland woods as well as till plains and clay lake plains of post-glacial lake beds. Based on the map from Little (1977), Harms (1990) noted that the range of Fraxinus profunda is “quite discontinuous,” but addition of recent records shows a more continuous range (Fig. -

SALAZAR1, CÁSSIO VAN DEN BERG2 & ALEX POPOVKIN3 1Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, Apartado Postal 70-367, 04510 México, Distrito Federal, México; E-mail: [email protected] 2Universidade Estadual de Feira de Santana, Departamento de Ciências Biológicas, Av. Transnordestina s.n., 44036-900, Feira de Santana, Bahia, Brazil 3Fazenda Rio do Negro, Entre Rios, Bahia, Brazil Abstract The monospecific genus Discyphus, previously considered a member of Spiranthinae (Orchidoideae: Cranichideae), displays both vegetative and floral morphological peculiarities that are out of place in that subtribe. These include a single, sessile, cordate leaf that clasps the base of the inflorescence and lies flat on the substrate, petals that are long-decurrent on the column, labellum margins free from sides of the column and a column provided with two separate, cup-shaped stigmatic areas. Because of its morphological uniqueness, the phylogenetic relationships of Discyphus have been considered obscure. In this study, we analyse nucleotide sequences of plastid and nuclear DNA under maximum parsimony -

Bromeliads Bromeliads Are a Family of Plants (Bromeliaceae, the Pineapple Family) Native to Tropical North and South America
A Horticulture Information article from the Wisconsin Master Gardener website, posted 19 March 2012 Bromeliads Bromeliads are a family of plants (Bromeliaceae, the pineapple family) native to tropical North and South America. Europeans fi rst found out about bromeliads on Columbus’ second trip to the New World in 1493, where the pineapple (Ananas sp.) was being cultivated by the Carib tribe in the West Indies. The commercial pineapple (Ananas comosus) is native to southern Brazil and Paraguay. After the colonization of the New World it was rapidly transported to all areas of the tropics, and now is widely grown in tropical and sub- tropical areas. The only A collection of bromeliads placed on a tree at Costa Flores, Costa Rica. bromeliad to occur north of the tropics is Spanish “moss” (Tillandsia usneoides). It is neither Spanish nor a moss, but an epiphytic bromeliad. It doesn’t look much like a typical Commercial pineapple, Ananas comosus, bromeliad, though, with its long scaly stems and reduced in the fi eld. fl owers. Bromeliads are monocots, many of which, like their grass relatives, have a special form of photosynthesis that uses a variation of the more usual biochemical pathways to allow them to use water more effi ciently. Even though they come from the tropics, this helps those that are epiphytes contend with life in the treetops where there is limited water and a real danger of drying out. There are about 2500 species Many bromeliads are tropical and several thousand hybrids epiphytes. and cultivars. Many have brightly colored leaves, fl owers or fruit, and range in size from moss-like species of Tillandsia to the enormous Puya raimondii from the Andes which produces a fl owering stem up to 15 feet tall. -

An Overview of Chilli Thrips, Scirtothrips Dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management
Chapter 3 An Overview of Chilli Thrips, Scirtothrips dorsalis (Thysanoptera: Thripidae) Biology, Distribution and Management Vivek Kumar, Garima Kakkar, Cindy L. McKenzie, Dakshina R. Seal and Lance S. Osborne Additional information is available at the end of the chapter http://dx.doi.org/10.5772/55045 1. Introduction The industrial revolution, globalization and international trade liberalization are some of the important events that have afforded vast opportunities for invasive insect species to establish in new territories [1]. These invasive species, facing no challenge by their natural enemies, thrive well in the new environment [2]. In addition to the disturbance they cause to the biodiversity, pest invasion in any country results in increased pressure on biosecurity, national economy, and human health management systems [1, 3, 4]. Apart from economic loss in managing them, these pests pose a significant detrimental impact on tourism and recreational value of the region, which further adds in indirect economic damage to the nation [5]. Of this large group of invasive pests, thrips are one of the most important members. The invasive status gained by thrips across the globe is due to their high degree of polyphagy, wide host range and easy dispersal that can be anthropogenic or natural (wind-mediated). The earliest fossil record of order Thysanoptera dates back to the Late Triassic period, from the state of Virginia in the United States and the country Kazakhstan in Central Asia, but their abundance was rare until the Cretaceous period from which many specimens of Thysanoptera have been recorded [6]. The order Thysanoptera was given its current taxonomic rank by an Irish entomologist, A. -

The Genus Guzmania (Bromeliaceae) in Venezuela
The genus Guzmania (Bromeliaceae) in Venezuela Compiled by Yuribia Vivas Fundación Instituto Botánico de Venezuela Bruce Holst & Harry Luther Marie Selby Botanical Gardens The genus Guzmania was described by Hipólito Ruiz and José Pavón in 1802 in the "Flora Peruviana et Chilensis." The type species is Guzmania tricolor Ruiz & Pav. The name honors Spanish naturalist Anastasio Guzmán, a student of South American plants and animals (Grant & Zijlstra 1998). Species of Guzmania are distributed from the southern USA (Florida) and Mexico to Brazil and Peru, including the Most species of Guzmania are found in cloud forests at middle elevations. Antilles; they are largely absent from lowland Amazonia. Photograph by Yuribia Vivas. Figure modified from Smith & Downs, Flora Neotropica. Guzmania is placed in the subfamily Tillandsioideae, and is distinguished from other members of the subfamily (Vriesea,Tillandsia, Catopsis, Racinaea, Alcantarea, Mezobromelia, and Werauhia) by having polystichously arranged flowers (that is, arranged in many planes on the inflorescence axis), white, whitish, yellow, or greenish petals that lack nectar scales, and having generally reddish brown-colored seeds. In general aspect, Guzmania is difficult to distinguish from Mezobromelia since both are polystichously flowered and may have similar color schemes, but the presence of nectar scales in Mezobromelia and absence inGuzmania separates them. Approximately 200 species and 17 varieties of Guzmania are known, making it the third largest genus in the subfamily, after Tillandsia and Vriesea. The table below is a listing of Guzmania in Venezuela, with synonymy, types, phenology, and distribution. Column two contains photographs of live plants and the third column, type specimens.
