  • 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 composed of the stem and its lateral appendages: leaves, buds, and flowers. Leaves are arranged in different patterns (phyllotaxis): alternate, opposite, whorled, and spiral. 2. Stems provide support to the leaves, buds, and flowers. They conduct water and nutrients and produce new cells in meristems (shoot apical meristem, primary and secondary meristems). 3. Dicot stems and monocot stems are usually different. Dicot stems tend to have vascular bundles distributed in a ring, whereas in monocot stems they tend to be scattered. 4. Stems are composed of the following: epidermis, cortex and pith, xylem and phloem, and periderm. 5. Secondary xylem is formed by the division of cells in the vascular cambium and is called wood. The bark is composed of all of the tissues outside the vascular cambium, including the periderm (formed from cork cambium) and the secondary phloem.

  • Principal Types of Vegetative Shoot Apex Organization in Vascular Plants1
    PRINCIPAL TYPES OF VEGETATIVE SHOOT APEX ORGANIZATION IN VASCULAR PLANTS1 RICHARD A. POPHAM Department of Botany and Plant Pathology, The Ohio State University, Columbus 10 Before progress can be made in research, a problem must be recognized. Once the problem has been perceived, a research program may be directed toward a solution. The problem of how and where a shoot grows and the organization of the shoot apex was apparently first conceived by Kaspar Friedrich Wolff (1759). Although his observations on the structure, formation, and growth of cells were fantastically inaccurate, he made a great contribution to our knowledge of the growing plant by setting forth a new and important problem. In a very real sense, Wolff is the father of developmental plant anatomy. Disagreement is the life blood of many research problems. Strenuous opposition is often engendered by a dogmatic statement or a theory which is proposed as a universal truth. Opposition to Wolff's (1759) original proposition regarding the organization and growth of shoot apices prompted plant anatomists, some 85 years later, to investigate the truth of the statement. The factual solution of the problem of shoot apex organization had its beginnings in the work of Nageli (1845). Following this work on many lower cryptogams, Nageli concluded that the cells of all tissues of the shoot of cryptogams and higher plants have their genesis in a single apical cell. The new-born apical cell theory supported by Hofmeister (1851) and others provided the impetus for a renewed, vigorous attack on the problem of shoot apex organization. A little later a new proposal, Hanstein's (1868) histogen theory was born of more careful observations and in a mind unfettered by the prevailing fanaticism of the apical cell theorists.

  • Pruning Fruit Trees: Rules of Shoot Growth
    Pruning Fruit Trees: Rules of Shoot Growth Pruning fruit trees is usually perceived as a very difficult task for the inexperienced. This is due primarily to the uncertainty involved in deciding what to prune, where to cut, and how much wood to remove. Pruning decisions can be made much easier if we know the way a tree grows naturally. The purpose of this article is to present some basic principles and observations on shoot growth. While these rules were developed with tree fruit in mind, they are generally applicable to deciduous trees in the landscape. Rules of Shoot Growth 1. If two branches are identical in length, and diameter, and they emerge from the tree trunk at the same location, they will have the same growth potential. Such limbs have comparable hormone levels, leaf area, and they will receive comparable nutrients and growth promoting substances from the roots. 2. The steeper the angle of a branch, the more vigorously it will grow, provided all the other conditions are identical. This rule is especially important since it gives you, the pruner, a glimpse into the future about growth potential of limbs in a tree. Upright limbs, which form an angle with the trunk of 30 degrees or less, are apt to be too vigorous, grow inappropriately large, and by the nature of their vigor, be quite unproductive. Conversely, a limb that is flat and forms an angle of 90 degrees or more with the trunk will be weak and display little if any terminal growth. Further, vigorous upright shoots may grow from these flat limbs, and pose contin-ual problems in the future.

    J. AMER. Soc. HORT. SCI. 115(1):131-135. 1990. Effect of Photoperiod and Shoot Decapitation on Flowering of Leucospermum ‘Red Sunset’ Daniel G. Malan1 and Gerard Jacobs Department of Horticulture, University of Stellenbosch, Stellenbosch, 7600, South Africa Additional index words. short-day plant, night break Abstract. Incandescent light night break (NB) and day continuation (DC) prevented flower formation in Leucosper- mum R.Br. CV. Red Sunset. Natural short days (NSD) during winter were inductive for flowering of intact shoots until 28 Aug. (Southern Hemisphere), but only until 24 July for decapitated shoots. Vegetative axillary buds released from correlative inhibition by shoot decapitation were less responsive to inductive short days (SD) than distal axillary buds on intact shoots. At least 42 inductive SD cycles were required for normal flowering after cessation of shoot growth. The effective length of the NB depended on the length of the NSD of winter. A 2-hr NB prevented flowering in vegetative buds released from correlative inhibition by shoot decapitation on 3 Mar., but was inadequate for axillary buds on shoots decapitated on 1 May. When the NB was begun during winter and discontinued before natural day (ND) lengths became too long in spring, the flowering time was delayed. Vegetative and reproductive growth of Leucospermum CV. cence development occurs during winter (May to September), Red Sunset (Proteaceae) follow a seasonal sequence. Plants grow and the flowers open in early spring (September to October). vegetatively during late spring and summer (November to March, The inflorescence is a capitulum arising from an axillary bud Southern Hemisphere) and individual shoots have strong apical distally situated on a shoot (Jacobs, 1985).

  • Character Description in Phylogenetic Analysis: Insights from Agnes Arber's Concept of the Plant
    Character Description in Phylogenetic Analysis: Insights from Agnes Arber's Concept of the Plant By: BRUCE K. KIRCHOFF Kirchoff, B. K. 2001. Character description in phylogenetic analysis: insights from Agnes Arber's concept of the plant. Annals of Botany 88: 1203-1214. Made available courtesy of Oxford University Press: http://aob.oxfordjournals.org/cgi/reprint/88/6/1203 ***Note: Figures may be missing from this format of the document Abstract: Throughout her work Agnes Arber argues for an inclusive, synthetic concept of the vascular plant as `consisting of a unification of every phase of its existence'. Her view of the leaf as a partial-shoot reflects this unification by relating the part (leaf) to the whole (shoot). According to Arber's view of the plant, the part can be fully understood only in the context of the whole. Morphological character description as it is currently practiced in systematics isin sharp contrast with this holistic view of plant structure. Systematic characters are removed from their context when they are described. This problem is greatest when characters are expressed verbally. Verbal descriptions convey little of the content of the character. A shift from verbal to visual charactersallows systematists to capture more information, including some of the context in which the character occurs. By using a photograph, the fringe on a labellum of Alpinia spp. (Zingiberaceae) can be viewed in the context of the labellum in a way that the word `fringe' cannot convey. The use of pictorial charactersalso allows reliable data storage and retrieval from databases, much as DNA sequences are currently being stored and retrieved.

    NAT. HIST. BULL. SIAM Soc. 40:201-203 BOOK REVIEW Plants From the Markets of Thailand by Christiane Jacquat. Editions Duang Kamol (DK), Bangkok, 1990; pp. 251, price 390 Baht. Dr. Jacquat, a Swiss archaeo-ethnobotanist, has produced an unusual, colourful, and certainly unique book combining botany and culture. The bulk of the book includes the identities, Thai and English names, short descriptions, uses, and 341 colour plates for 241 wild and cultivated plants in the following categories: edible and medicinal plants, ornamental plants, plants used for packaging, and a short section about two trees with useful wood/resin and bark. There is also information about Thailand's geography, ethnic composition, climate, forests, and food. The edible and medicinal plants include algae and fungi, fern allies and ferns, and flowering plants. Ornamental plants have fern allies and ferns as well as flowering plants, while only flowering plants are discussed under packaging plants. There is a glossary of botanical terms, list of references, and indices to botanical, Thai, and English names. I do have some comments that could be used to improve future editions of the book. The introductory part about Thai forests should be revised since much of it is incorrect. The term "jungle" is not a scientific term and should be replaced with tropical monsoonal evergreen (not tropical rain) forest. Although the terms "dry evergreen" and "hill evergreen" forests are commonly, but unfortunately uncritically, used for Thai forests, these ill-defined and inappropriate terms create confusion and need to be properly ex­ plained. "Mixed deciduous" forests are not, as the author writes, a cross between "dry evergreen" and deciduous forests.
