We will have more information on this experience during our April meeting, and will express thanks to the several people who provided leadership and willing hands for this important event. Contents 1 Our Show & Sale provides great opportunities for our members to sell their plants and display Pres. Message 1 their exceptional specimens. Board Minutes 2 This activity also enables our society to serve the growing number of succulent gardeners and April Program 3 raise funds to support services to members throughout the year. April Mini-Show 4 You have undoubtedly noticed that this issue of On the Dry Side is both later than usual and March Mini-Show 5 different in appearance. Also, due to technical issues, this issue does not include March Mini- CSSA Show & Sale 6 show Winners. These changes have resulted from the hassle of working with a recent update of computer software. Microsoft Office 365 appears to provide many desirable new capabilities, Open Greenhouse 7 and definitely requires time on the learning curve. Show Winners 8 Our April meeting will feature Stan Verkler’s talk about his recent visit to South Africa. Spring Sale Pics 9 This will be another interesting and informative presentation that adds substantial value to our Officers, Chairs 10 monthly meetings, along with the enjoyment of getting together with friends and growers of succulent plants. -

Caryophyllales: a Key Group for Understanding Wood
Botanical Journal of the Linnean Society, 2010, 164, 342–393. With 21 figures Caryophyllales: a key group for understanding wood anatomy character states and their evolutionboj_1095 342..393 SHERWIN CARLQUIST FLS* Santa Barbara Botanic Garden, 1212 Mission Canyon Road, Santa Barbara, CA 93110, USA Received 13 May 2010; accepted for publication 28 September 2010 Definitions of character states in woods are softer than generally assumed, and more complex for workers to interpret. Only by a constant effort to transcend the limitations of glossaries can a more than partial understanding of wood anatomy and its evolution be achieved. The need for such an effort is most evident in a major group with sufficient wood diversity to demonstrate numerous problems in wood anatomical features. Caryophyllales s.l., with approximately 12 000 species, are such a group. Paradoxically, Caryophyllales offer many more interpretive problems than other ‘typically woody’ eudicot clades of comparable size: a wider range of wood structural patterns is represented in the order. An account of character expression diversity is presented for major wood characters of Caryophyllales. These characters include successive cambia (more extensively represented in Caryophyllales than elsewhere in angiosperms); vessel element perforation plates (non-bordered and bordered, with and without constrictions); lateral wall pitting of vessels (notably pseudoscalariform patterns); vesturing and sculpturing on vessel walls; grouping of vessels; nature of tracheids and fibre-tracheids, storying in libriform fibres, types of axial parenchyma, ray anatomy and shifts in ray ontogeny; juvenilism in rays; raylessness; occurrence of idioblasts; occurrence of a new cell type (ancistrocladan cells); correlations of raylessness with scattered bundle occurrence and other anatomical discoveries newly described and/or understood through the use of scanning electron microscopy and light microscopy. -

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. -
1 Relacion De Algunas Plantas Y Hongos
Acta Botánica Mexicana (1997), 39:1-42 RELACION DE ALGUNAS PLANTAS Y HONGOS MEXICANOS RAROS, AMENAZADOS O EN PELIGRO DE EXTINCION Y SUGERENCIAS PARA SU CONSERVACION ANDREW P. VOVIDES VICTOR LUNA Y GUADALUPE MEDINA Instituto de Ecología, A.C. Apartado postal 63 91000 Xalapa, Veracruz RESUMEN Se presenta un listado revisado de algunas especies de plantas mexicanas silvestres consideradas como raras, amenazadas o en peligro de extinción, desglosadas por categoría UICN, tipo de vegetación y entidad federativa (estado); también por primera vez se incluye una relación de hongos amenazados. Se discute el papel de los jardines botánicos en la conservación de las mismas. Se realiza además un análisis numérico de las especies registradas por familia, categoría UICN y vegetación. ABSTRACT A revised list of some rare, threatened and endangered plant species of Mexico is presented. Listing is by IUCN category, vegetation type and state. A list of threatened fungi is included for the first time. The role of the botanic gardens in the conservation of these species is discussed. A numerical analysis of the reported species by family, IUCN category and vegetation is also presented. INTRODUCCION El primer listado de especies de plantas amenazadas para México (Vovides, 1981) así como la versión actualizada de la misma (Vovides, 1988) se compilaron por medio de encuestas enviadas a los taxónomos colaboradores. Las categorías de la Unión Internacional para la Conservación de la Naturaleza (UICN) (Anónimo, 1981) fueron asignadas subjetivamente según el criterio de los expertos, como una primera aproximación para evaluar la problemática de las especies en peligro. Estos listados son útiles tanto para los jardines botánicos como para las autoridades involucradas en la toma de decisiones para protegerlas. -

It is made available under aCC-BY-NC-ND 4.0 International license. 5 Abstract 6 Peter Medawar’s ‘An Unsolved Problem of Biology’1 was one of several formal attempts to 7 provide an explanation for the evolution of senescence, the increasing risk of mortality and 8 decline in reproduction with age after achieving maturity. Despite ca. seven decades of 9 theoretical elaboration aiming to explain the problem since Medawar first outlined it, we 10 argue that this fundamental problem of biology remains unsolved. Here, we utilise 11 demographic information2,3 for 308 multicellular species to derive age-based trajectories of 12 mortality and reproduction that provide evidence against the predictions of the classical, still 13 prevailing, theories of ageing1,4,5,6. These theories predict the inescapability of senescence1,4, 14 or its universality at least among species with a clear germ-soma barrier5,6.
