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. -
Plant Terminology
PLANT TERMINOLOGY Plant terminology for the identification of plants is a necessary evil in order to be more exact, to cut down on lengthy descriptions, and of course to use the more professional texts. I have tried to keep the terminology in the database fairly simple but there is no choice in using many descriptive terms. The following slides deal with the most commonly used terms (more specialized terms are given in family descriptions where needed). Professional texts vary from fairly friendly to down-right difficult in their use of terminology. Do not be dismayed if a plant or plant part does not seem to fit any given term, or that some terms seem to be vague or have more than one definition – that’s life. In addition this subject has deep historical roots and plant terminology has evolved with the science although some authors have not. There are many texts that define and illustrate plant terminology – I use Plant Identification Terminology, An illustrated Glossary by Harris and Harris (see CREDITS) and others. Most plant books have at least some terms defined. To really begin to appreciate the diversity of plants, a good text on plant systematics or Classification is a necessity. PLANT TERMS - Typical Plant - Introduction [V. Max Brown] Plant Shoot System of Plant – stem, leaves and flowers. This is the photosynthetic part of the plant using CO2 (from the air) and light to produce food which is used by the plant and stored in the Root System. The shoot system is also the reproductive part of the plant forming flowers (highly modified leaves); however some plants also have forms of asexual reproduction The stem is composed of Nodes (points of origin for leaves and branches) and Internodes Root System of Plant – supports the plant, stores food and uptakes water and minerals used in the shoot System PLANT TERMS - Typical Perfect Flower [V. -

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. -
Common Name: BARTRAM’S AIR-PLANT
Common Name: BARTRAM’S AIR-PLANT Scientific Name: Tillandsia bartramii Elliott Other Commonly Used Names: Previously Used Scientific Names: Tillandsia myriophylla Small, T. setacea Swartz var. tenuifolia Chapman, T. pinifolia Leconte Family: Bromeliaceae (air-plant) Rarity Ranks: G4/S2 State Legal Status: Special Concern Federal Legal Status: none Federal Wetland Status: none Description: Perennial, evergreen herb attached to tree trunks and branches, forming dense clusters of stiffly spreading, pointed leaves. Leaves 6 - 16 inches (15 - 40 cm) long and less than ¼ inch (0.5 cm) wide except for the widened, flat, triangular base; leaves are covered with pinkish-gray scales. Flower stalk 3 - 6 inches (8 - 15 cm) long, sometimes branched, covered by many red, pointed, overlapping bracts, with 5 - 20 flowers that emerge from beneath the bracts. Flowers 1 - 1¾ inches (3 - 4.5 cm) long, narrow and tubular, with 3 pale green sepals and 3 purple petals. Fruit a narrow, brown, tubular capsule about 1 inch (2.5 - 3 cm) long, opening into 3 parts to release plumed seeds. Similar and Related Rare Species: Three other species of air-plants are of Special Concern. Needle-leaved air-plant (Tillandsia setacea) leaves resemble pine needles; it grows on evergreen hardwood trees in bluff forests in Glynn, Laurens, and Ben Hill Counties. Quill-leaf air-plant (T. fasciculata) has stiff, leathery leaves up to 1 inch (2.5 cm) wide at the base; it is known from one site in Camden County where it grows on live oaks in a maritime hammock. Ball-moss (T. recurvata) occurs in Camden and Glynn Counties where it forms dense “balls” of curved leaves on live oaks in maritime forests.
