CoP15 Prop. 28 CONVENTION ON INTERNATIONAL TRADE IN ENDANGERED SPECIES OF WILD FAUNA AND FLORA ____________________ Fifteenth meeting of the Conference of the Parties Doha (Qatar), 13-25 March 2010 CONSIDERATION OF PROPOSALS FOR AMENDMENT OF APPENDICES I AND II A. Proposal Delist Euphorbia misera from Appendix II. B. Proponent Mexico and the United States of America* C. Supporting statement 1. Taxonomy 1.1 Class: Magnoliophyta 1.2 Order: Magnoliopsida 1.3 Family: Euphorbiaceae 1.4 Genus, species or subspecies, including author and year: Euphorbia misera Benth. 1.5 Scientific synonyms: Euphorbia benedicta, Trichosterigma benedictum, T. miserum 1.6 Common names: English: cliff spurge, Saint Benedict spurge French: Spanish: hamácj, jumetón, lechosa, golondrina 1.7 Code numbers: 2. Overview Euphorbia misera, native to Mexico and the United States of America, has been listed in CITES Appendix II since 1975. According to CITES trade data, international trade does not appear to be a factor affecting the status of this species. We are proposing to delete this species from the CITES Appendices. Since listing, there has been minimal CITES-recorded international trade (1 shipment of 5 artificially propagated specimens from the United States in the 1990s). The species is intrinsically vulnerable to extinction due to its limited and fragmented distribution and low reproductive output. Euphorbia misera is used medicinally in Mexico, which use appears to be highly localized. The species is known in commercial cultivation in the United States, where there is domestic * The geographical designations employed in this document do not imply the expression of any opinion whatsoever on the part of the CITES Secretariat or the United Nations Environment Programme concerning the legal status of any country, territory, or area, or concerning the delimitation of its frontiers or boundaries. -
Acanthacereus Pentagonus by Karla Halpaap-Wood 1 Vol
Vol. 56, No. 5 September - October 2019 Acanthacereus pentagonus by Karla Halpaap-Wood www.hcsstex.org 1 Vol. 56, No. 5 September - October 2019 From the editor Karla Halpaap-Wood I want to thank everybody who contributed to this edition of the KK. On the regular webpage http://www.hcsstex.org and Facebook page https://www.facebook.com/Houston- CactusSucculentSociety/ you can find information about the club, programs and events. We now also have an active Facebook group https://www.facebook.com/groups/1049635895242129/?source_id=254317392276 for you to discuss anything related to cacti and succulents. Membership Kathy Fewox HCSS celebrated its anniversary on July 24, 2019 by having a potluck dinner. Seventeen members attended the meeting. There was lots of wonderful food to enjoy, and good company. Cindy Gray donated four Tephro- cactus plants, two for the raffle and two as door prizes. Our meeting on August 28 was attended by nineteen members who braved the threat of rain and flooding to reach the Multi-Service Center. Most of us managed to get there with little trouble, as the worst of the rain had moved south of the 610 loop by about 6:30 p.m. However, Robert Smith got stuck in rain-delayed traffic on his trip in from Highlands, and didn’t arrive until the meeting was officially over. Also attending were four guests: Chris Balshaw, Aditi Nabar, Ziona Burkett (a Florida friend of BonnieJean Grady’s), and Mariela Hiraldo (daughter of Alan Schachter). Dave Thomas donated a Carnegiea gigantea (Giant Saguaro) as a door prize. It isn’t giant yet, but winner Frank Lee is hoping it will grow into its name. -

CACSS 1 February 2020 20 YEARS IN THE ATACAMA, LAND OF THE COPIAPOAS Photos and Text by Wendell S. ‘Woody’ Minnich Similar to the coast of Namibia, the coastal and inland regions of northern Chile, known as the Atacama, are mainly watered by amazing fogs, “the Camanchacas.” These fog- fed regions, in two of the driest deserts in the world, have some of the most interesting cactus and succulents to be found anywhere. The Atacama of northern Chile has an endemic genus considered by many to be one of the most dramatic to have ever evolved-the Copiapoa. This ancient genus is also believed to be tens of thousands of years old, and there are those who feel it might well be on its way out! The ocean currents that affect the coastal Atacama have changed considerably over the last hundreds of years, and now its only source of moisture is primarily from consistent dense fogs. Some of these areas rarely, if ever, get rain, and the plants that have evolved there live almost entirely off the heavy condensation from the Camanchaca. There are many different Copiapoa species ranging from small quarter-sized subterranean geophytes, to giant 1,000-year-old, 300-head mounding clusters. -

Ist Astrophytum Coahuilense Ein Naturhybrid? 37
M6000E Heft 2 Februar 1993 Kakten Jahrgang 44 und andere Sukkulenten Kakteen und andere Sukkulenten Monatlich erscheinendes Organ der als Herausgeber genannten Gesellschaften Heft 2 • Februar 1993 • Jahrgang 44 • ISSN 0022 7846 Zum Titelbild: Astrophytum coahuilense (Moeller) Kayser gehört zu den interessantesten Pflanzen innerhalb der morphologisch so variablen Gattung Astrophytum Lemaire. Es ähnelt einerseits in der äußeren Wuchsform genau Astrophytum myriostigma Lemaire: wie dieses besitzt es meist fünf Rippen und ist dicht mit weißen Wollflocken bedeckt. Sobald jedoch die prächtigen, großen Blüten erscheinen wird andererseits klar, daß eine enge Verwandtschaft zu Astrophytum capricorne (Dietrich) Britton & Rose bestehen muß. Sie sind im Schlund orange bis tiefrot gefärbt und bei Befruchtung entwickelt sich eine purpur-violette, samenreiche Frucht. Die überraschende Mischung der vegetativen und generativen Merkmale bei Astrophytum coahuilense aus den Astrophytum-Linien des südlichen und nördlichen mexikanischen Hochlandes ist auch der Grund für einen noch heute andauernden Meinungsunterschied, wie diese schönen Pflanzen taxonomisch oder in ihrer evolutiven Entwicklung einzustufen sind. Einen Lösungsvor schlag hierzu finden Sie in einem Beitrag auf Seite 37. Astrophytum coahuilense sollte man an einem sonnigen Platz pflegen und von April bis Oktober maßvoll wässern. Ein rein mineralisches Substrat, wie beispielsweise Ziegelsplitt mit Sand gemischt, bietet dann nach trockener Überwinterung um 15-20°C die optimalen Voraussetzungen für regelmäßige Blüten während der sommerlichen Wachtumszeit.

Héctor M. Hernández*, Carlos Gómez-Hinostrosa and Gibrán Hoffmann Departamento de Botánica, Instituto de Biología, Universidad Nacional Autónoma de México, Apartado postal 70-233, 04510 Mexico D. F., Mexico. *Correspondent: [email protected] Abstract. With the aim of assessing the extent of geographical rarity of Mexican Cactaceae, we calculated the distribution size (area of occupancy) of 142 species from the Chihuahuan Desert. In addition, using 2 variables (number of localities and range size), we preliminarily assessed their conservation status using the current IUCN Red List criteria. The results showed enormous variation in the areas of occupancy, although from the biogeographic and conservation perspective the most exceptional group comprises the extremely narrow endemics (42 species), whose range is restricted to areas smaller than 10 km2. Our results reinforce the reputation of this plant family as exceptionally rare geographically. We suggest that geographical rarity of Cactaceae in the Chihuahuan Desert is a natural phenomenon; however, we propose that the range of several species has been infl uenced by human activities. Regarding the conservation status of the species, 75 of them are categorized as Least concern. The remaining 67 species (47.2%) fall in 1 of the 3 categories of threat (27 Vulnerable, 11 Endangered, and 29 Critically endangered). These fi gures confi rm the critical conservation status of Mexican Cactaceae.
