Richards, Major Professor Palms provide valuable commercial resources in the tropics and are dominant species in tropical lowland forests. While general biology of palms is well studied, there are gaps in the literature on palm growth through life stages and in response to environmental conditions. Literature gaps on palm growth could be caused by the slow growth of palms; it is difficult to monitor morphology and architecture for the periods of time necessary to capture changes. Acoelorrhaphe wrightii is a threatened palm native to southern Florida with an unusual adult architecture. The purpose of this dissertation was to study growth A. wrightii throughout its life stages and in response to changes in environmental conditions. In order to do study growth, I first had to understand the evolutionary history and types of vegetative branching in palms to identify vegetative branching possibilities in A. wrightii. I described branching types for 1903 species from all 181 genera using literature reviews and hands-on analysis. I then studied adult morphology and architecture in a common garden setting by monitoring leaf morphology, ramet growth and architecture of A. wrightii in two gardens in Miami, FL, over a two year period. I tested the effects of water and light on germination and growth of juvenile plants vii in a mesocosm where water and light were manipulated, following growth for a year. Finally, I compared leaf morphology and architecture of adult individuals in four populations in Belize and Florida. I found five branching types were present in the palms: lateral axillary branching, shoot apical division, false vivipary, abaxial branching and leaf- opposed branching. In the garden, Acoelorrhaphe wrightii displayed two types of lateral axillary branching: basal suckering and rhizomatous branching. The two branching types produced tiers in adult clones, which were used to model architecture. Ramets had an establishment period and growth varied seasonally in establishing and established phases. Low water levels and full sun yielded greater germination of A. wrighti and produced juveniles with a greater number of leaves, more root mass and more branches. Variability between populations and environmental conditions was observed in adult individuals in the field but differences were minimal. viii TABLE OF CONTENTS CHAPTER PAGE INTRODUCTION ................................................................................................................ 1 LIST OF REFERENCES ......................................................................................... 4 CHAPTER I: DISTRIBUTION OF VEGETATIVE BRANCHING IN THE PALMS (ARECACEAE) ................................................................................................................... 7 ABSTRACT ............................................................................................................. 8 INTRODUCTION .................................................................................................... 9 MATERIALS AND METHODS .............................................................................. 11 RESULTS .............................................................................................................. 14 DISCUSSION ........................................................................................................ 23 TABLES ................................................................................................................ 31 FIGURES .............................................................................................................. 36 APPENDICES ....................................................................................................... 47 ACKNOWLEDGMENTS ......................................................................................

  • Aiphanes Grandis Borchs
    Palm Conservation – Palm Specialist Group Aiphanes grandis Borchs. & Balslev Status: Endangered (EN) Common name None recorded Natural range Aiphanes grandis is endemic to the western slopes of the Andes mountains in Ecuador, at elevations between 1000 and 2000 m. It occurs in cloud forest in the central and southern parts of the country. Recognition characteristics It is a large, solitary palm tree, with a stem up to 20 m tall and 10–20 cm in diameter. The stem and leaves are fiercely armed with long, black spines. The leaf blade is 200–250 cm long with up to 50 leaflets on each side, briefly jagged at apex, inserted in groups and pointing in different directions. The inflorescence is 1–1.5 m long, with up to 200 spreading branches. Flowers are white to pale yellow and fruits 2–3 cm in diameter, dull green and covered with brown, loosely attached bristles. The combination of jagged leaflets and large size distinguishes the species from all other South American palms. Natural history Little is known about the natural history of the species. The palm heart is edible, and its seeds are sometimes pureed and cooked with crude cane sugar to form a nougat-like paste. Threats to survival The estimated loss of potential habitat for A. grandis, based on habitat modeling, is 62%, most of which has occurred over the last 30–40 years. The west Andean mountain forest in southern and central Ecudor, where A. grandis occurs, harbors a high number of endemic plant species. It is also the home to remnant populations of such conspicuous palm species as Ceroxylon ventricosum and C.

  • Species Delimitation and Hybrid Identification of Acrocomia Aculeata
    Species delimitation and hybrid identification of Acrocomia aculeata and A. totai by genetic population approach Brenda D´ıaz1, Maria Zucchi2, Alessandro Alves-Pereira1, Joaquim Azevedo-Filho2, Mariana Sanit´a2, and Carlos Colombo2 1State University of Campinas 2Instituto Agronomico October 9, 2020 Abstract To the Neotropical genus Acrocomia (Arecaceae) is attributed eight species with a wide distribution in America. A. aculeata and A. totai are the most important species because of their high economic potential for oil production. However, there is no consensus in their classification as different taxons and their distinctiveness is particularly challenging due to morphological similarities with large plasticity of the traits. In addition, there is doubt about the occurrence of interspecific hybrids between both species. In this study, we applied a genetic population approach to assessing the genetic boundaries, diversity and to identify interspecific hybrids of A. aculeata and A. totai. Thirteen loci of simple sequence repeat (SSR) were employed to analyze twelve populations representing a wide distribution of species, from Minas Gerais, Brazil to Formosa, Argentina. Based on the Bayesian analysis (STRUCTURE and NewHybrids) and Discriminant Analysis of Principal Components (DAPC), our study supports the recognition of A. aculeata and A. totai as two species and the estimates of genetic parameters revealed more genetic diversity in A. totai (HE=0.551) than in A. aculeata (HE=0.466). We obtained evidence of hybridization between the species and that admixed individuals were assigned as F2 hybrids. In conclusion, this study showed the usefulness of microsatellite markers to elucidate the genetic boundaries of A. aculeata and A. totai, supporting their classification as different species and increase our knowledge about genetic diversity at the level of populations and species.

  • Red Ring Disease of Coconut Palms Is Caused by the Red Ring Nematode (Bursaphelenchus Cocophilus), Though This Nematode May Also Be Known As the Coconut Palm Nematode
    1 Red ring disease of coconut palms is caused by the red ring nematode (Bursaphelenchus cocophilus), though this nematode may also be known as the coconut palm nematode. This disease was first described on coconut palms in 1905 in Trinidad and the association between the disease and the nematode was reported in 1919. The vector of the nematode is the South American palm weevil (Rhynchophorus palmarum), both adults and larvae. The nematode parasitizes the weevil which then transmits the nematode as it moves from tree to tree. Though the weevil may visit many different tree species, the nematode only infects members of the Palmae family. The nematode and South American palm weevil have not yet been observed in Florida. 2 Information Sources: Brammer, A.S. and Crow, W.T. 2001.

  • Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands
    SMITHSONIAN INSTITUTION Contributions from the United States National Herbarium Volume 52: 1-415 Monocotyledons and Gymnosperms of Puerto Rico and the Virgin Islands Editors Pedro Acevedo-Rodríguez and Mark T. Strong Department of Botany National Museum of Natural History Washington, DC 2005 ABSTRACT Acevedo-Rodríguez, Pedro and Mark T. Strong. Monocots and Gymnosperms of Puerto Rico and the Virgin Islands. Contributions from the United States National Herbarium, volume 52: 415 pages (including 65 figures). The present treatment constitutes an updated revision for the monocotyledon and gymnosperm flora (excluding Orchidaceae and Poaceae) for the biogeographical region of Puerto Rico (including all islets and islands) and the Virgin Islands. With this contribution, we fill the last major gap in the flora of this region, since the dicotyledons have been previously revised. This volume recognizes 33 families, 118 genera, and 349 species of Monocots (excluding the Orchidaceae and Poaceae) and three families, three genera, and six species of gymnosperms. The Poaceae with an estimated 89 genera and 265 species, will be published in a separate volume at a later date. When Ackerman’s (1995) treatment of orchids (65 genera and 145 species) and the Poaceae are added to our account of monocots, the new total rises to 35 families, 272 genera and 759 species. The differences in number from Britton’s and Wilson’s (1926) treatment is attributed to changes in families, generic and species concepts, recent introductions, naturalization of introduced species and cultivars, exclusion of cultivated plants, misdeterminations, and discoveries of new taxa or new distributional records during the last seven decades.
