Call it jicamilla or Berlandier's nettlespurge by Jim Seeden Its scientific name is Jatropha cathartica and I suspect it's not well known by any name. I first saw one while we were evaluating a ranch which eventually became Las Estrellas Preserve (the Star Cactus Ranch) after being purchased by The Nature Conservancy. The ranch constitutes their effort to conserve the endangered star cactus. Every ecosystem has a specific combination of plant species. Jatropha cathartica is often found in ecosystems with star cacti, manfredas, Fitch's hedgehog cacti, and horse crippler cacti, none of these are common plants, along with some typical Valley shrubs. The soils in such ecosystems are mostly clay. Those who enjoy growing succulents find jicamillas attractive and unusual. The 8 to 10 inch flower stalks are tipped with a cluster of small, bright rose-red flowers with five petals each. One oddity is that the individual flowers are unisexual but in each cluster will be several of each sex, usually in a ratio of about 3 male to 1 female. When pollinated the female flowers produce round, green, three seeded pods. Blooms can occur from February through November but are most common in the summer. The leaves are a pubescent gray-green and palmately five lobed, like fingers of your hand. Each lobe is pointed and bears a jagged set of teeth. One of its most distinctive features is a very large tuber found just below ground level. Those who grow them for display sometimes plant them with the tuber above ground leaving only the lower taproot in the ground. While it elicits curiosity viewing, it seems to be a bizarre practice to me. I grow one with the tuber almost entirely underground and it seems very happy. The plants are perennial but go dormant in the winter and lose all their stems and leaves. I should warn you that, while it's called jicamilla and has a large tuber, it should not be confused with jicama which is found in grocery stores. They're not even in the same genus. Jicamilla is NOT edible. It's a member of the spurge family. I close by noting that Jatropha cathartica is another species endemic to Texas and a northern portion of Mexico. The Valley does contain an amazing diversity of wild things! .

The purpose of a 5-year review is to evaluate whether or not the species’ status has changed since it was listed (or since the most recent 5-year review). Based on the 5-year review, we recommend whether the species should be removed from the list of endangered and threatened species, be changed in status from endangered to threatened, or be changed in status from threatened to endangered. Our original listing as endangered or threatened is based on the species’ status considering the five threat factors described in section 4(a)(1) of the Act.

Chapter 4 Phytomorph and Geomorph Identification ©
1 Chapter 4 Phytomorph and Geomorph Identification © This Chapter is based on three published works: (1) a paper by Hugh O Neall (1944) that identifies two New World plants (sunflower and chili peppers) in the Voynich manuscript; (2) a paper of Tucker and Talbert (2013) which identified 39 plants in the Voynich as indigenous to the New World; (3) a paper by Tucker and Janick (2016) which extended the list to 59 species. Although many of the illustrations of the Voynich Codex on first blush could be considered bizarre or whimsical (See Figure in Chapter 14) most contain morphological structures which permit botanical identification. Many enthusiasts have attempted to analyze the plants of the Voynich Codex, but few are knowledgeable plant taxonomists or botanists, despite their large web presence. Most of the plant identification has been predicated on the conclusion that the Voynich is a 15th century European manuscript (Friedman 1962). The principal reports in a web report by non botanists Edith and Erica Sherwood (http:www.edithsherwood.comn/coyhnich_botanical_plants) who identifies he plants as Mediterranean based on their premise that Voynich is a 15th century Italian manuscript and claims to find signature of Leonardo da Vinci in voynich drawings. We respectfully disagree with both assertions. The first exception to the conclusion that the Voynich plants were European is a short remarkable 1944 paper in Speculum (a refereed journal of the Medieval Academy of America) by the distinguished plant taxonomist, the Rev./Dr. Hugh O’Neill (1894–1969), former Director of the Herbarium (official acronym LCU) at the Catholic University of America (CUA) in Washington, D.C.

Revisión Periódica De Reservas De La Biosfera
2_.l~-´ 'p0o9+bhdsa REVISIÓN PERIÓDICA DE RESERVAS DE LA BIOSFERA [Enero de 2018] UNESCO - Programa el Hombre y la Biosfera (MAB) - Formulario de revisión periódica de reservas de la biosfera – Enero 2018 3_.l~-´ 'p0o9+bhdsa INTRODUCCIÓN La Conferencia General de la UNESCO, en su 28ª sesión, adoptó la Resolución 28 C/2.4 en el Marco Estatutario de la Red Mundial de Reservas de la Biosfera. Este texto define en particular, los criterios para que un área esté cualificada para ser designada como reserva de la biosfera (Artículo 4). Además, el Artículo 9 contempla una revisión periódica cada 10 años, que consiste en un informe que debe preparar la autoridad competente, en base a los criterios del Artículo 4 y enviarlo al secretariado del Estado correspondiente. El texto del Marco Estatutario se recoge en el tercer anexo. El formulario que se facilita a continuación sirve para ayudar a los Estados a preparar su informe nacional, de acuerdo con el Artículo 9, y para actualizar en la Secretaria los datos disponibles de la reserva de la biosfera correspondiente. Este informe deber permitir al Consejo Internacional de Coordinación (CIC) del Programa MAB, revisar cómo cada reserva de la biosfera está cumpliendo con los criterios del Artículo 4 del Marco Estatutario y en particular con las tres funciones. Cabe señalar que en la última parte del formulario (Criterios y Avances Logrados), se pide que se indique cómo las reservas de la biosfera cumplen con cada uno de estos criterios. La UNESCO utilizará de diversas maneras la información presentada en esta revisión periódica: (a) para la evaluación de la reserva de la biosfera por parte del Comité Consultivo Internacional de las Reservas de Biosfera y por la Mesa del Consejo Internacional de Coordinación del MAB; (b) para utilizarla en un sistema de información accesible a nivel mundial, en particular la red UNESCO-MAB y publicaciones, facilitando así la comunicación y la interacción entre personas interesadas en las reservas de la biosfera en todo el mundo.
