Leaf Anatomy and C02 Recycling During Crassulacean Acid Metabolism in Twelve Epiphytic Species of Tillandsia (Bromeliaceae)
Int. J. Plant Sci. 154(1): 100-106. 1993. © 1993 by The University of Chicago. All rights reserved. 1058-5893/93/5401 -0010502.00 LEAF ANATOMY AND C02 RECYCLING DURING CRASSULACEAN ACID METABOLISM IN TWELVE EPIPHYTIC SPECIES OF TILLANDSIA (BROMELIACEAE) VALERIE S. LOESCHEN,* CRAIG E. MARTIN,' * MARIAN SMITH,t AND SUZANNE L. EDERf •Department of Botany, University of Kansas, Lawrence, Kansas 66045-2106; and t Department of Biological Sciences, Southern Illinois University, Edwardsville, Illinois 62026-1651 The relationship between leaf anatomy, specifically the percent of leaf volume occupied by water- storage parenchyma (hydrenchyma), and the contribution of respiratory C02 during Crassulacean acid metabolism (CAM) was investigated in 12 epiphytic species of Tillandsia. It has been postulated that the hydrenchyma, which contributes to C02 exchange through respiration only, may be causally related to the recently observed phenomenon of C02 recycling during CAM. Among the 12 species of Tillandsia, leaves of T. usneoides and T. bergeri exhibited 0% hydrenchyma, while the hydrenchyma in the other species ranged from 2.9% to 53% of leaf cross-sectional area. Diurnal malate fluctuation and nighttime atmospheric C02 uptake were measured in at least four individuals of each species. A significant excess of diurnal malate fluctuation as compared with atmospheric C02 absorbed overnight was observed only in T. schiedeana. This species had an intermediate proportion (30%) of hydrenchyma in its leaves. Results of this study do not support the hypothesis that C02 recycling during CAM may reflect respiratory contributions of C02 from the tissue hydrenchyma. Introduction tions continue through fixation of internally re• leased, respired C02 (Szarek et al. -

Epiphytic Plants of Citrus in Florida1 Ramdas Kanissery and Mongi Zekri2
HS1305 Epiphytic Plants of Citrus in Florida1 Ramdas Kanissery and Mongi Zekri2 Abstract Epiphytic plants found on Florida citrus can be classified into three broad categories: Epiphytes are a group of plants that grow on citrus by using the trees for anchorage and support. These plants are not 1. Tillandsias (or bromeliads), members of the pineapple in direct contact with the ground and obtain moisture and family nutrients from the air and rainfall. Epiphytes make up an essential part of biodiversity in citrus groves and these 2. Orchids plants present no threat to the citrus trees. 3. Nonflowering plants (ferns, true mosses, and lichens) Introduction Vines are not listed among the epiphytes, as they are The thousands of acres of citrus groves in Florida provide terrestrial (ground-growing) in origin. an environment for many epiphytic plant species. “Epi- phytic” is a Greek term meaning “on the plant,” and is most commonly used to describe plants growing on trees and Tillandsias shrubbery. Epiphytes growing on trees are also referred to There are five major species of Tillandsia found in citrus as “air plants” because they have no physical contact with groves. These flowering plants are commonly referred to as the land. Epiphytic plants are an important addition to “bromeliads” and are all members of the pineapple family biodiversity; however they are often incorrectly considered (Bromeliaceae). These plants use their hosts for anchorage as weeds among agricultural tree crops, including citrus and support. Also, there has been no evidence of these in wet and humid areas. Nevertheless, these plants do not species acting as a host for citrus pests or pathogens. -

EENY161 Mexican Bromeliad Weevil (suggested common name), Metamasius callizona (Chevrolat) (Insecta: Coleoptera: Curculionidae)1 Barba Larson and J. Howard Frank2 Barber, the smallest of the three and native to Florida, Cuba, and the Dominican Republic, has been collected in Florida infrequently. Unlike Metamasius callizona, its presence does not threaten populations of native bromeli- ads in Florida’s natural areas. The third species, Metamasius hempipterus sericeus (Olivier), was first reported in Florida in Miami-Dade County in 1984 and has since become an important pest of sugarcane, bananas, and ornamental palms.

Credits: H. Nadel, University of Florida Introduction and History Metamasius callizona (Chevrolat) has no accepted common name, but it has been referred to as the “Evil Weevil” by bromeliad enthusiasts throughout Florida, as a result of the destruction it has caused to native populations of bromeli- ads in the southern portion of the state.

Water Relations of Bromeliaceae in Their Evolutionary Context
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by Apollo Botanical Journal of the Linnean Society, 2016, 181, 415–440. With 2 figures Think tank: water relations of Bromeliaceae in their evolutionary context JAMIE MALES* Department of Plant Sciences, University of Cambridge, Downing Street, Cambridge CB2 3EA, UK Received 31 July 2015; revised 28 February 2016; accepted for publication 1 March 2016 Water relations represent a pivotal nexus in plant biology due to the multiplicity of functions affected by water status. Hydraulic properties of plant parts are therefore likely to be relevant to evolutionary trends in many taxa. Bromeliaceae encompass a wealth of morphological, physiological and ecological variations and the geographical and bioclimatic range of the family is also extensive. The diversification of bromeliad lineages is known to be correlated with the origins of a suite of key innovations, many of which relate directly or indirectly to water relations. However, little information is known regarding the role of change in morphoanatomical and hydraulic traits in the evolutionary origins of the classical ecophysiological functional types in Bromeliaceae or how this role relates to the diversification of specific lineages. In this paper, I present a synthesis of the current knowledge on bromeliad water relations and a qualitative model of the evolution of relevant traits in the context of the functional types. I use this model to introduce a manifesto for a new research programme on the integrative biology and evolution of bromeliad water-use strategies. The need for a wide-ranging survey of morphoanatomical and hydraulic traits across Bromeliaceae is stressed, as this would provide extensive insight into structure– function relationships of relevance to the evolutionary history of bromeliads and, more generally, to the evolutionary physiology of flowering plants. -

It is a 7.5 acre conservation area, owned by the City of Key West. The KWBG requested that The Institute for Regional Conservation (IRC) conduct a floristic evaluation of its natural areas and grounds and to provide recommendations. Study Design On August 9-10, 2005 an inventory of all vascular plants was conducted at the KWBG. All areas of the KWBG were visited, including the newly acquired property to the south. Special attention was paid toward the remnant natural habitats. A preliminary plant list was established. Plant taxonomy generally follows Wunderlin (1998) and Bailey et al. (1976). Results Five distinct habitats were recorded for the KWBG. Two of which are human altered and are artificial being classified as developed upland and modified wetland. In addition, three natural habitats are found at the KWBG. They are coastal berm (here termed buttonwood hammock), rockland hammock, and tidal swamp habitats. Developed and Modified Habitats Garden and Developed Upland Areas The developed upland portions include the maintained garden areas as well as the cleared parking areas, building edges, and paths. -
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.

Morphological and Molecular Evidence of Arbuscular Mycorrhizal Fungal Associations in Costa Rican Epiphytic Bromeliads1
BIOTROPICA 37(2): 245–250 2005 10.1111/j.1744-7429.2005.00033.x Morphological and Molecular Evidence of Arbuscular Mycorrhizal Fungal Associations in Costa Rican Epiphytic Bromeliads1 Annette R. Rowe2 and Anne Pringle Department of Plant and Microbial Biology, 111 Koshland Hall, University of California, Berkeley, California 94720-3102, U.S.A. ABSTRACT Arbuscular mycorrhizal fungi influence the growth, morphology, and fitness of a variety of plant species, but little is known of the arbuscular mycorrhizal (AM) fungal associations of plant species in forest canopies. Plant species’ associations with AM fungi are most often elucidated by examining the roots for fungal structures; however, morphological data may provide a limited resolution on a plant’s mycorrhizal status. We combined a traditional staining technique with a molecular marker (the 18S ribosomal gene) to determine whether or not a variety of epiphytic bromeliads form arbuscular mycorrhizal fungal associations. Using these methods we show that the epiphytic bromeliad Vriesea werkleana forms arbuscular mycorrhizal fungal associations with members of the genus Glomus. AM fungal sequences of this plant species formed three distinct clades nested within a larger Glomus clade; two of the clades did not group with any previously sequenced lineage of Glomus. Novel clades may represent novel species. Although Vriesea werkleana is associated with multiple AM fungal species, each individual plant is colonized by a single lineage. The combination of morphological and molecular methods provides a practical approach to the characterization of the mycorrhizal status of epiphytic bromeliads, and perhaps other tropical epiphytes.
