SLADE Division of Biological Sciences, University of Kansas, Lawrence, Kansas 66045 In several recent studies the branching system of trees was assumed to constitute a geometric series with constant branching ratio indicative of the adaptive geometry of a species. However, in a population of young Cottonwood trees {Populus deltoides), branching ratios varied significantly within the crown of individual trees and among experimental groups of different growth vigor. With a simple mathematical model, based on the symmetric branch system of the tropical tree Tabebuia rosea, we showed that, with increasing size of a tree, the geometric (exponential) increase in branch number per order must be reduced, if a physiologically optimum leaf area per terminal branch is to be maintained. Also, branching ratios based on centripetal branch ordering are not predictive of tree development and ignore information essential to characterize the architectural model of a tree. Bifurcation ratios thus appear to be unsuited as indicators of the adaptive geometry of trees. Introduction should ultimately aid in understanding the optimi• During the past decade interest in the mathe• zation of the structure-function relationship for a matical analysis of branched biological systems such certain set of environmental conditions, i.e., the as botanical trees or bronchial, arterial, and neural "adaptive strategy" of trees.

Systematic Botany (2007), 32(3): pp. 660–670 # Copyright 2007 by the American Society of Plant Taxonomists Taxonomic Revisions in the Polyphyletic Genus Tabebuia s. l. (Bignoniaceae) SUSAN O. GROSE1 and R. G. OLMSTEAD Department of Biology, University of Washington, Box 355325, Seattle, Washington 98195 U.S.A. 1Author for correspondence ([email protected]) Communicating Editor: James F. Smith ABSTRACT. Recent molecular studies have shown Tabebuia to be polyphyletic, thus necessitating taxonomic revision. These revisions are made here by resurrecting two genera to contain segregate clades of Tabebuia. Roseodendron Miranda consists of the two species with spathaceous calices of similar texture to the corolla. Handroanthus Mattos comprises the principally yellow flowered species with an indumentum of hairs covering the leaves and calyx. The species of Handroanthus are also characterized by having extremely dense wood containing copious quantities of lapachol. Tabebuia is restricted to those species with white to red or rarely yellow flowers and having an indumentum of stalked or sessile lepidote scales. The following new combinations are published: Handroanthus arianeae (A. H. Gentry) S. Grose, H. billbergii (Bur. & K. Schum). S. Grose subsp. billbergii, H. billbergii subsp. ampla (A. H. Gentry) S.

Seed Dispersal of Woody Plants in Tropical Forests: Concepts, Examples and Future Directions
CHAPTER ELEVEN Seed dispersal of woody plants in tropical forests: concepts, examples and future directions HELENE C. MULLER-LANDAU University of Minnesota BRITTA DENISE HARDESTY University of Georgia Introduction Understanding seed dispersal is critical to understanding plant population and community dynamics (Nathan & Muller-Landau 2000), especially in tropical forests where seed rain of virtually all plant species is sparse and patchy (Hubbell et al. 1999; Muller-Landau et al. 2002). Seed rain determines potential population growth rates and spatial patterns, as well as the relative influences of post- dispersal processes such as seed prédation (e.g. Wright et al. 2000), microhabitat requirements for establishment (e.g. Svenning 1999) and density-dependent sur- vival (e.g. Harms et al. 2000). Despite its importance, we know very little about seed dispersal of tropical trees, because it has been studied in only a tiny pro- portion of the many tropical tree species and seed dispersers, and because the patterns that have been observed have largely eluded easy generalization. Just as there is a greater diversity of plant species and animal species in the tropics than in other regions, there is also a greater diversity of seed-dispersal strategies and patterns. Seed dispersal by animals predominates - it is the main strategy of 70%-90% of tropical forest plant species (Willson et al. 1989) - and involves a tremendous diversity of animal species and behaviours. Birds, bats, arboreal and terrestrial mammals (everything from mice to elephants), ants, dung beetles, even ñsh can disperse seeds (Levey et al. 1994). Animals may con- sume fruit and drop, spit or defecate the seeds, carry seeds in their coats or scatter-hoard seeds for later consumption. -
A Preliminary List of the Vascular Plants and Wildlife at the Village Of
A Floristic Evaluation of the Natural Plant Communities and Grounds Occurring at The Key West Botanical Garden, Stock Island, Monroe County, Florida Steven W. Woodmansee [email protected] January 20, 2006 Submitted by The Institute for Regional Conservation 22601 S.W. 152 Avenue, Miami, Florida 33170 George D. Gann, Executive Director Submitted to CarolAnn Sharkey Key West Botanical Garden 5210 College Road Key West, Florida 33040 and Kate Marks Heritage Preservation 1012 14th Street, NW, Suite 1200 Washington DC 20005 Introduction The Key West Botanical Garden (KWBG) is located at 5210 College Road on Stock Island, Monroe County, Florida. 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. -
Flowering Trees of Bangalore by S. Karthikeyan
FLOWERING TREES OF BANGALORE S.Karthikeyan Email : [email protected] Website : www.wildwanderer.com 1 FFFLOWERING TTTREES Bangalore’s charm as a Garden City may have diminished. However, some of the trees that perhaps earned its name are still to be seen and cherished. For those of us who would want to simply immerse ourselves in that moment appreciating the beauty of each of these flowering trees that dot Bangalore it really does not matter …we will continue to do so. For those who would want to have more information about these trees, I have tried to put together some, along with pictures for 56 species that are often seen. This includes similar / related species that are dealt under a main species. Hope you find it useful. Note : • Flowering seasons mentioned in the following pages are from available literature. Onset of flowering is, however, subject to prevailing environmental conditions and location. • All vernacular names mentioned are Kannada names. 2 AAACKNOWLEDGEMENTS This compilation is a result of several years of observation, reading books on the topic, and interacting with experts and other like-minded people. The effort started with a series of postings on bngbirds as and when I observed a species in bloom. In the process about two dozen species were covered. Due to popular request from several subscribers to bngbirds this series was repeated with some additions. And recently the same content was suitably edited and posted on www.wildwanderer.com . Here again, it met with an overwhelming response. This prompted and encouraged me to add some more species taking the total to over 50 species.
