Cycad Conservation: Zamia encephalartoides in Colombia amia encephalartoides is a cycad Znative to a network of deep, dry canyons carved into the Eastern Andes of Colombia by the Chicamocha River. The hot, dry, rocky and open landscape where it grows is quite different from that of other Colombian Zamia, which typically grow in humid forests. With tough, leathery leaves and large, colorful cones, Zamia encephalartoides is remarkably adapted to this arid environment and superficially resembles Encephalartos, an African genus that typically grows in similar dry, open environments. In fact, the name, “Zamia encephalartoides” means “Encephalartos-like Zamia”. This unique cycad species was described by Dennis Stevenson only a decade ago, and has not been studied extensively.

This project was focused on populations at the extreme northeast and northwest of the reported range of the species, both of which were not yet represented in living collections. Documented localities were visited, as well as other accessible sites with suitable habitat. The westernmost known population (Taylor County, FL), was located, surveyed, documented and collected. In addition, a small population even further to the west was also discovered, further extending the known range of this species. The northeasternmost location (Glynn County, GA), documented only once in 1971, was re-surveyed. This population was not found. Zamia integrifolia Project Report: Page 1 of 11. A unique lineage Zamia integrifolia L.f. is the only cycad native to the continental United States. It has great ornamental appeal and is also of great interest to science, coming from the most ancient lineage of extant seed plants. It is quite variable in habit and morphology throughout its range, from forms with narrow leaflets and few leaves in the south of its range to large specimens with wider leaflets and holding many leaves in the north-central part of its range and many other variants in between.

Zamiaceae, Cycadales) and Evolution in Cycadales
The complete chloroplast genome of Microcycas calocoma (Miq.) A. DC. (Zamiaceae, Cycadales) and evolution in Cycadales Aimee Caye G. Chang1,2,3, Qiang Lai1, Tao Chen2, Tieyao Tu1, Yunhua Wang2, Esperanza Maribel G. Agoo4, Jun Duan1 and Nan Li2 1 South China Botanical Garden, Chinese Academy of Sciences, Guangzhou, China 2 Shenzhen Fairy Lake Botanical Garden, Chinese Academy of Sciences, Shenzhen, China 3 University of Chinese Academy of Sciences, Beijing, China 4 Department of Biology, De La Salle University, Manila, Philippines ABSTRACT Cycadales is an extant group of seed plants occurring in subtropical and tropical regions comprising putatively three families and 10 genera. At least one complete plastid genome sequence has been reported for all of the 10 genera except Microcycas, making it an ideal plant group to conduct comprehensive plastome comparisons at the genus level. This article reports for the first time the plastid genome of Microcycas calocoma. The plastid genome has a length of 165,688 bp with 134 annotated genes including 86 protein-coding genes, 47 non-coding RNA genes (39 tRNA and eight rRNA) and one pseudogene. Using global sequence variation analysis, the results showed that all cycad genomes share highly similar genomic profiles indicating significant slow evolution and little variation. However, identity matrices coinciding with the inverted repeat regions showed fewer similarities indicating that higher polymorphic events occur at those sites. Conserved non-coding regions also appear to be more divergent whereas variations in the exons were less discernible indicating that the latter comprises more conserved sequences. Submitted 5 September 2019 Phylogenetic analysis using 81 concatenated protein-coding genes of chloroplast (cp) Accepted 27 November 2019 genomes, obtained using maximum likelihood and Bayesian inference with high Published 13 January 2020 support values (>70% ML and = 1.0 BPP), confirms that Microcycas is closest to Corresponding authors Zamia and forms a monophyletic clade with Ceratozamia and Stangeria.

Pagán-Jiménez1* and Julio C. Lazcano-Lara2 Author address: 1Faculty of Archaeology, Leiden University (The Netherlands), and Programa de Maestría en Arqueología, Centro de Estudios Avanzados de Puerto Rico y el Caribe (Puerto Rico). 2Laboratory for Integrative Biology, Departamento de Biología, Universidad de Puerto Rico, Río Piedras (Puerto Rico). * Corresponding author: [email protected] Received: February 26, 2013 Volume: 4:52-58 Published: April 30, 2013 © 2013 Society of Ethnobiology Abstract: This is the first report of the occurrence of wild Zamia pumila L. Zamiaceae populations on various volcanic substrates in the piedmont area of south central Puerto Rico. Data acquisition and its field confirmation were possible after the identification of toponymic names in old and current maps, and historic documents of the island in which one of the indigenous names for the genus (marunguey [marungüey] or marungueyes) has been used for naming some localities. These preliminary data have deep implications for paleo- and neoethnobotanical research, and for population ecology of the species in Puerto Rico, because they expand the traditionally accepted range for the species on the island. Zamia has been described as one of the main food plants among pre- and post-Columbian inhabitants in two islands of the Greater Antilles, Hispaniola and Puerto Rico, where the most sophisticated pre-Columbian society of the Antilles, the Taínos, emerged. Our findings suggest that Zamia might have been more available to humans, as a food source, than previously thought.

Andrew P Vovides* Instituto de Ecología, Mexico *Corresponding author: Andrew P Vovides, Instituto de Ecología, Mexico Submission: January 26, 2019; Published: February 5, 2019 Mini Review Looking at cycads from a distance the un-experienced would Cycads are amongst the most ancient group of living seed be excused for calling them palms, since these plants bear long plants known and have a fossil history that dates to more than 200 feather-like leaves crowning the apex of a relatively short thick million years [1]. They were at their height during the times of the stem or trunk. The trunks may be solitary or branched depending dinosaurs, forming part of the world vegetation during the Mesozoic on age and species. Infact it would be more correct to say that palms are cycad-like since the cycad families are of far greater age than the era (160million years ago). They superficially resemble palms or but cones. They are gymnosperms that include conifers, and cycads even ferns though totally unrelated since they do not bear flowers occur in separate sexes there being female and male plants. Cycads palms that are classified as flowering plants. When you have a closer the conifers; the seed-bearing cone bears naked seeds, hence the had a much wider distribution during the historic past with fossils look at cycad cones you will find a certain resemblance to those of term gymnosperm in that the seed lacks the ovary wall that forms found in Alaska, Russia, Britain and the USA.

A New Species of Zamia (Zamiaceae) from Costa Rica
BRENESIA 73-74: 29-33, 2010 A new species of Zamia (Zamiaceae) from Costa Rica Rafael H. Acuña C. School of Biology, University of Costa Rica, P.O. Box 11501-2060 San José, Costa Rica. Email: [email protected] (Received: September 1, 2010) ABSTRACT. Zamia gomeziana sp. nov. is described from material collected from Fila de Matama, in Limón Province, Costa Rica. It is distinguished from Zamia fairchildiana L.D. Gómez by its straighter leaflets with longer tips, longer megastrobilus peduncle and thicker megastrobilus with a shorter sterile apex. A discussion about the possible relationships of this new taxon with other existing Zamia species is briefly outlined. Most aspects of the biology of this species are unknown. RESUMEN. Zamia gomeziana sp. nov. se describe a partir de material recolectado en la fila de Matama, en la provincia de Limón, Costa Rica. Se distingue de Zamia fairchildiana L.D. Gómez por sus foliolos más rectos y con ápices más largos, así como por los pedúnculos de los megaestróbilos más largos y megaestróbilos más gruesos con el ápice estéril más corto. Se discuten brevemente las relaciones de este taxon con otras especies de Zamia. La mayor parte de los aspectos de la biología de esta especie se desconocen. KEY WORDS. Zamia, new species, Costa Rica, Fila de Matama, Limón Province Zamia L. is the second most speciose genus in the related Z. fairchildiana L.D. Gómez and Z. Cycadales Pers. ex Bercht. & J.

Baker County Extension Alicia R. Lamborn Environmental Horticulture Agent 1025 West Macclenny Avenue Macclenny, FL 32063 904-259-3520 email: [email protected] http://baker.ifas.ufl.edu Coontie Zamia pumila (Z. floridana) Plant Description: Coontie is an evergreen, palm-like plant known as a cycad. Cycads are a general group of plants that produce cones instead of flowers, and the Coontie happens to be Florida’s only native cycad. Unlike Sago cycads, Coontie may resemble a fern having both a soft appearance and a soft touch. Over time, the plant produces suckers to form a mounding shrub. The rusty brown cones provide winter interest, while the bright red-orange seeds produced on female cones further add to this plant’s attractiveness. Mature Size: 1-5 feet tall; 3-5 foot spread Growth Rate: Moderate Plant Habit: Mounding Plant Spacing: 1-2 feet (minimum) Ornamental Characteristics & Uses: Foliage Color: Dark green Cones: Rusty brown male and female cones emerge in late winter; bright red-orange seeds develop and ripen by the following autumn. Attracts Wildlife: Birds; larval food plant for the Atala butterfly (S. Florida only) Uses: Woodland and shade gardens; tropical gardens; low maintenance groundcover; containers; coastal landscapes (moderately salt tolerant); floral arrangement greenery Growing Requirements: Cold Hardiness Zone(s): 8B-11 Hardy Temp: 15oF (cold damage may occur in the 20’s) Exposure: Tolerates full sun to deep shade; partial sun is best Water Needs: Low; very drought tolerant Soil Tolerances: Grows in any soil type. Soil pH: Acid to Alkaline Maintenance: Easy/Low General Care & Growing Tips: Coonties prefer well-drained soil.
