Photos by D. Amaya (DA), E. Baron (EB), W. Collier (WC), B. Holst (BH); J. Meerman (JM), L. Munsey (LM), M. Paredes (MP), P. Nelson (PN), D. Troxell (DT) Support from the Marie Selby Botanical Gardens, Ian Anderson’s Caves Branch Jungle Lodge, Environmental Resource Institute - University of Belize [fieldguides.fieldmuseum.org] [964] version 1 11/2017 The genus Tillandsia in Belize includes approximately 30 species, which can be found growing singly, or in large colonies, and can usually be identified by their non-spiny leaves, often flattened inflorescence branches, symmetrical sepals, free petals, and often colorful flower clusters which fade quickly after flowering. They are most always epiphytic growing on trees and shrubs to gain better access to sunlight; an occasional species is found on rocks or on the ground (e.g., T. dasyliriifolia). Many have gray/silvery, scaly leaves (e.g., T. pruinosa, T. streptophylla). The scales (or “trichomes”) help capture water and nutrients from the environment. Some spe- cies form water-holding tanks by means of their overlapping leaves. These tanks are rich with nutrients from the environment, provide sustenance for the plant, and create important habitat for animals in the forest canopy. The genus is found throughout Belize, but reaches its peak of species diversity on the high summits of the Maya Mountains.

Plunkett ABSTRACf. Peach palm (Bactris gasipaes Kunth.) is the only Neotropical palm domesticated since pre-Columbian times. It plays an important role not only at the local level due to its very nutritious fruits, but also in the international market for its gourmet palm heart. Phylogenetic relationships of the peach palm with wild Bactris taxa are still in doubt, and have never been addressed using molecular sequence data. We generated a chloroplast DNA phylogeny using intergenic spacers from a sampling of cultivars of Bactris gasipaes as well as putative wild relatives and other members of the genus Baciris.

  • A Laid-Back Trip Through the Hennigian Forests
    A laid-back trip through the Hennigian Forests Evgeny V. Mavrodiev1, Christopher Dell1,* and Laura Schroder2,3,* 1 University of Florida, Florida Museum of Natural History, Gainesville, FL, USA 2 Department of Anatomy and Neurobiology of University of Tennessee, University of Tennessee Health Science Center Washington, Memphis, TN, USA 3 Washington, Wyoming, Alaska, Montana and Idaho Medical Education Program, University of Idaho, Moscow, ID, USA * These authors contributed equally to this work. ABSTRACT Background. This paper is a comment on the idea of matrix-free Cladistics. Demon- stration of this idea's efficiency is a major goal of the study. Within the proposed framework, the ordinary (phenetic) matrix is necessary only as ``source'' of Hennigian trees, not as a primary subject of the analysis. Switching from the matrix-based thinking to the matrix-free Cladistic approach clearly reveals that optimizations of the character-state changes are related not to the real processes, but to the form of the data representation. Methods. We focused our study on the binary data. We wrote the simple ruby-based script FORESTER version 1.0 that helps represent a binary matrix as an array of the rooted trees (as a ``Hennigian forest''). The binary representations of the genomic (DNA) data have been made by script 1001. The Average Consensus method as well as the standard Maximum Parsimony (MP) approach has been used to analyze the data. Principle findings. The binary matrix may be easily re-written as a set of rooted trees (maximal relationships). The latter might be analyzed by the Average Consensus method. Paradoxically, this method, if applied to the Hennigian forests, in principle can help to identify clades despite the absence of the direct evidence from the primary data.

  • Conservation of Cuban Palms Leiva & Verdecia
    Conservation of Cuban palms Leiva & Verdecia Conservation of Cuban palms 2 Angela Leiva1 and Raúl Verdecia 1National Botanic Garden, Cuba and 2Las Tunas Botanic Garden Cuba Cuban native flora is rich in palms: 15 genera, two subgenera, 81 species, six hybridogenous species and nine infraspecific taxa are known from the various ecosystems of the country, bearing 87% of species endemism. Nowadays, integrated conservation actions are developed by botanic gardens of the country in order to halt threats that are facing several Cuban endemic species of palms. Under the auspices of the National and Las Tunas Botanic Gardens, and with the financial support of a grant from Fauna and FIora International and Global Trees Campaign, a program of expeditions to natural areas was prepared in order to verify the conservation status information from field survey work and to implement priority conservation activities for globally threatened palms of Cuba. The selected species were: Coccothrinax pauciramosa, Coccothrinax crinita, Colpothrinax wrightii, Copernicia brittonorum, Copernicia fallaensis, Roystonea lenis and Roystonea stellata. Between September 2004 and September 2005, a total of seven field expeditions were made to the following places: Eastern Cuba: Sierra de Nipe, Holguín; eastern Guantánamo Central Cuba: south-east of Ciénaga de Zapata; north of Ciego de Ávila Western Cuba: Las Pozas and Sabanalamar, Pinar del Río Activities undertaken included a field survey to check current conservation status and the conservation needs of palm species, and provision of training and public education with the hosting of two workshops highlighting conservation good practice and sustainable use for local inhabitants who depend on palm resources for their livelihood.
