My very first plant was purchased well, which is their main attraction to me. I now have from Folkestone Woolworths costing me 2s-6d over 150 specimens, many of which were purchased (12.5p). The plant was Ferocactus herrerae, it was in in the 60s and are now over 50 years old. a 50mm pot and the size of a golf ball – 42 years on Origin of the species the plant is in a 375mm pot and is still growing well. I joined the Cactus and Succulent Society of Great The name ‘Turbinicarpus’ has a double origin of Britain in 1969 and, with this newly-found source of Greek and Latin: information and contacts, my interest and Latin – ‘turbo, turbines’ – meaning ‘top’ knowledge rapidly increased. Greek – ‘karpos’ – meaning ‘fruit’. My interest in cacti is as keen today as it ever was The earliest member of Turbinicarpus was first and now I have more than 1000 plants in my described in 1927 by Bödecker as Echinocactus collection with a particular interest in Mexican schmiedickeanus. It was later included in the sub- miniatures such as Ariocarpus, Aztekium, genus Turbinicarpus, at this time a sub-genus of the Astrophytum etc. My particular passion however is genus Strombocactus.

    U.S. Fish & Wildlife Service Star Cactus (Astrophytum asterias) Recovery Plan September 2003 DISCLAIMER Recovery plans delineate reasonable actions which are believed to be required to recover and/or protect listed species. Plans are published by the U.S. Fish and Wildlife Service, sometimes prepared with the assistance of recovery teams, contractors, State agencies, and others. Objectives will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved as well as the need to address other priorities. Recovery plans do not necessarily represent the views or the official positions or approval of any individuals or agencies involved in the plan formulation, other than the U.S. Fish and Wildlife Service only after they have been signed by the Regional Director as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery tasks.

PLANT-OF-THE-MONTH: Cactus: Echinocactus, Ferocactus, Succulent: Monadenium, Jatropha Descriptions by Scott Bunnell: Echinocactus is a genus of cacti in the subfamily Cactoideae. It and Ferocactus are the two genera of barrel cactus. Members of the genus usually have heavy spination and relatively small flowers. The fruits are copiously woolly, which is one major distinction between Echinocactus and Ferocactus. Propagation is by seed. Perhaps the best known species is the golden barrel (Echinocactus grusonii) from Mexico, an easy-to-grow and widely cultivated plant.

  • A Tale of Two Cacti –The Complex Relationship Between Peyote (Lophophora Williamsii) and Endangered Star Cactus (Astrophytum Asterias)
    A Tale of Two Cacti –The Complex Relationship between Peyote (Lophophora williamsii) and Endangered Star Cactus (Astrophytum asterias). 1 2 2 TERRY, M. , D. PRICE , AND J. POOLE. 1Sul Ross State University, Department of Biology, Alpine, Texas 79832. 2Texas Parks and Wildlife Department, Wildlife Diversity Branch, 3000 S. IH-35, Suite 100, Austin, Texas 78704. ABSTRACT Astrophytum asterias, commonly called star cactus, is a federally listed endangered cactus endemic to the Tamaulipan thornscrub ecoregion of extreme southern Texas, USA, and Tamaulipas and Nuevo Leon, Mexico. Only three metapopulations totaling less than 4000 plants are presently known in Texas. Star cactus, known locally as “star peyote”, is highly sought by collectors. This small, dome-shaped, spineless, eight- ribbed cactus is sometimes mistaken for peyote (Lophophora williamsii), which grows in the same or adjacent habitats. Peyote is harvested from native thornscrub habitats in Texas by local Hispanic people and sold to peyoteros, licensed distributors who sell the peyote to Native American Church members. Annual peyote harvests in Texas approach 2,000,000 “buttons” (crowns). Although the peyoteros do not buy star cactus from harvesters, they cultivate star cactus in peyote gardens at their places of business and give star cacti to their customers as lagniappe. If even 0.1% of harvested “peyote” is actually star cactus, the annual take of this endangered cactus approaches the total number of wild specimens known in the U.S. This real but unquantifiable take, together with information from interviews with local residents, suggests the existence of many more star cactus populations than have been documented.

GENESIS 1:9 9 And God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so. Physical geographers have observed that the coast lines of the great continents and the mountain ranges generally run from north-east to south-west, and that these lines are in reality parts of great circles, tangent to the polar circle, and at right angles to a line drawn from the sun's center to the moon's, when these bodies are either in conjunction or in opposition. These circles are "the lines on which the thin crust of a cooling globe would be most likely to be ruptured by its internal tidal wave.

The research team from Russia’s Institute of Cell Biophysics team regenerated the plant from tissue found in the Siberian permafrost. It was a pioneering project that paves the way for other plant species to be revived. The plant the scientists brought back to life is called the Silene stenophylla. It is the oldest plant ever to be regenerated, beating the previous record for date palm seeds that were stored for 2,000 years in Israel. The plant had been stored away by squirrels during their hibernation 30 millennia ago, during the age of woolly mammoths. It froze and never thawed. The scientists believe that the regeneration of the Silene stenophylla plant means the permafrost is a natural store of ancient life forms, many of which could be recreated.

This document has been prepared by Mr James Grogan under contract with the CITES Secretariat.1 2. Background information can be found in two key CITES documents: CoP15 Doc. 55, submitted by the Management Authority of Switzerland, describes the issue under consideration in this report, whether certain genera of epiphytic cacti (seven as listed below) should be excluded from Appendix II based on the preponderance of artificially propagated compared to wild- collected specimens in international trade; IUCN Red List conservation status is reviewed, and trade data for gross exports of wild-collected specimens from range nations during 1975–2008 are presented; PC19 Doc. 14.1, prepared by the Chair of the Working Group on the Periodic Review with assistance from the Scientific Authority of Mexico, presents further analysis of trade data during 1998–2008 including the number of specimens of epiphytic cacti in trade that were artificially propagated, number of records and specimens that were wild collected, confiscated or seized, or of unknown origin during this period, and geographic ranges of species in question. Natural range, morphology & taxonomy of the epiphytic cacti 3. The Cactaceae are a New World family except for one species, the epiphytic Rhipsalis baccifera, which is also found in Africa, Madagascar and as far east as Sri Lanka. Seven genera are considered here: Disocactus, Epiphyllum, Hatiora, Lepismium, PseudoRhipsalis, Rhipsalis, and Schlumbergera. 4. These genera are grouped in two tribes of the subfamily Cactoideae within the Cactaceae family: Hylocereeae: Disocactus, Epiphyllum, PseudoRhipsalis Rhipsalideae: Hatiora, Lepismium, Rhipsalis, Schlumbergera 5.
