The Cycad Newsletter
Manuscript for: The Cycad Newsletter Title: A rescue, propagation, and reintroduction program for one of the most endangered lineage of cycads, Chigua in Northwestern Colombia Authors: Cristina López-Gallego1 Norberto López Alvarez2 Authors affiliations: 1 Instituto de Biología, Universidad de Antioquia, Colombia 2 Fundacion Biozoo, Córdoba, Colombia Correspondence author: Cristina López-Gallego E-mail: [email protected] Address: Kra. 75A #32A-26, Medellin, Colombia Phone: 574-238-6112 Chigua was first collected as an unicate by Francis Pennell in 1918. It was not until 1986 that a population conforming to Pennell's collection was relocated by the Colombian botanist Rodrigo Bernal. In 1990 Dennis Stevenson described two species of the new genus Chigua based on collections made by him, Knut Norstog, and the Colombian botanist Padre Sergio Restrepo in the only known locality for the two species in northwestern Colombia. By the time the next collections were made at the end of the 1990s (by Colombian botanists Alvaro Idárraga, Carlos A. Gutiérrez, Antonio Duque, and Cristina López-Gallego), the known population used for species descriptions had mostly disappeared because of habitat destruction and only a few scattered individuals were observed near the type locality. The two species of Chigua resemble some acaulous Zamia species, e.g. Zamia melanorrhachis D. Stev., in their overall morphology: a small subterraneous rhizome, few armed leaves with elliptic and papery toothed leaflets, and small cones with peltate unornamented sporophylls, and ovoid reddish seeds; but the presence of a central conspicuous vein distinguishes Chigua species from the rest of the Zamia lineage. The two species of Chigua can be separated by the shape of the mid-leaf leaflets, with C. -

Comparative Anatomy of Leaflets of Zamia Acuminata and Z
Comparative anatomy of leaflets of Zamia acuminata and Z. pseudomonticola (Zamiaceae) in Costa Rica Rafael Acuña-Castillo & Walter Marín-Méndez Escuela de Biología, Centro de Investigación en Estructuras Microscópicas (CIEMic), Universidad de Costa Rica, San José, Costa Rica. P.O. Box 11501-2060; [email protected], [email protected] Received 19-III-2012. Corrected 20-VIII-2012. Accepted 24-IX-2012. Abstract: The genus Zamia is morphologically and ecologically the most diverse of the order Cycadales. Throughout its history this genus has been restricted to the New World and is presently almost entirely restricted to the Neotropics. Unusual anatomical traits of the leaflets, such as the sunken stomata and thick cuticle, are common in this and related genera. The objective of this research was to study and compare the leaflet anatomy of Zamia acuminata and Z. pseudomonticola and establish possible phylogenetic relationships between the anatomical traits and the near relatives of these species. The leaf material was obtained from living plants and then processed for electron microscopy study. We found that both species are very similar to each other and to Z. fairchildiana, and that they share several unusual traits with other species of the genus, such as the parenchyma morphology, the spatial distribution of tissues between the veins and the stomata morphology. The main differ- ences between these species were seen in their fiber clusters and in the abundance of trichome basal cells on the epidermis. The anatomical similarities between the three species could be the result of their close phylogenetic relationship and the divergences between them could be the result of recent speciation during the Pleistocene, resulting from geological changes in Southern Costa Rica. -

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.

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. -

ASH2 'Paleobotany Laboratory. Williamson Building. University of Manchester, M13 nPL,UK <[email protected]>, ^Department of Earth and Planetary Sciences. University of New Mexico, Albuquerque, New Mexico 87120, USA <[email protected]> ABSTRACT —A single specimen collected in the Petrified Forest National Park, Arizona, from the Upper Triassic Chinle Formation, is the first bipinnate male sporophyll to be attributed to the order Cycadales. The sporophyll has a broad stalk, four sub-opposite pairs of first order pinnae and an apical pinna, all bearing short pinnules around their margins. Cuticle characters include: typically cycadalean epidermal cells; three types of trichomes, un-branched, branched, short conical; a haplocheilic stoma; monosulcate pollen. Putative pollen-sacs are compared with similar features in extant cycads which support the attribution. Androcycas gen. nov. is erected to accommodate the microsporangiate sporophyll as Androcycas santuccii sp. nov.

The cone is characterized by helically arranged, wedge-shaped microsporophylls, each with five or more spinelike projections extending from the rhomboid distal face. The vascular cylinder is dissected and produces paired traces to each microsporophyll. Three vascular bundles enter the base of the microsporophyll and divide to produce at least five vascular strands in the sporophyll lamina. Pollen sacs occur in two radial clusters near the lateral margins on the abaxial surface of the microsporophyll. Each cluster bears up to eight elongate pollen sacs that are fused for approximately half their length and display longitudinal dehiscence. Pollen sacs are sessile and attached to a vascularized, receptacle-like pad of tissue that is raised from the surface of the microsporophyll. Pollen is ovoid, psilate, and monosulcate. Although the affinities of this cone with the Cycadales are obvious, the complement of characters in the fossil is unique and thus does not permit assignment to an extant family. -
A New Cycad Stem from the Cretaceous in Argentina and Its Phylogenetic Relationships with Other Cycadales
bs_bs_banner Botanical Journal of the Linnean Society, 2012, 170, 436–458. With 6 figures A new cycad stem from the Cretaceous in Argentina and its phylogenetic relationships with other Cycadales LEANDRO CARLOS ALCIDES MARTÍNEZ1,2*, ANALÍA EMILIA EVA ARTABE2 and JOSEFINA BODNAR2 1División Paleobotánica, Museo Argentino de Ciencias Naturales ‘Bernardino Rivadavia’, Avda, Ángel Gallardo 470, Buenos Aires 1405, Argentina 2Facultad de Ciencias Naturales y Museo, División Paleobotánica, Universidad Nacional de La Plata, Paseo del Bosque s/n, La Plata 1900, Argentina Received 30 October 2011; revised 28 May 2012; accepted for publication 7 August 2012 The cycads are an ancient group of seed plants. Fossil stems assigned to the Cycadales are, however, rare and few descriptions of them exist. Here, a new genus of cycad stem, Wintucycas gen. nov., is described on the basis of specimens found in the Allen Formation (Upper Cretaceous) at the Salitral Ojo de Agua locality, Río Negro Province, Argentina. The most remarkable features of Wintucyas are: a columnar stem with persistent leaf bases, absence of cataphylls, a wide pith, medullary vascular bundles, mucilage canals and idioblasts; a polyxylic vascular cylinder; inverted xylem; and manoxylic wood. The new genus was included in a phylogenetic analysis and its relationships with fossil and extant genera of Cycadales were examined. In the resulting phylogenetic hypothesis, Wintucycas is circumscribed to subfamily Encephalartoideae, supporting the existence of a greater diversity of this group in South America during the Cretaceous. © 2012 The Linnean Society of London, Botanical Journal of the Linnean Society, 2012, 170, 436–458.
