Among them was Basarab Popa (well known as BB), a man of great soul, who probably was the most important East- European cactus collector of the last decade, who had a sudden and untimely death. Another great loss was the passing away of prof IPetre Dobrota, the author of the first Romanian book on cacti. Rest in Peace!

  • Star Cactus (Astrophytum Asterias)
    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.

  • Checklist of the Vascular Alien Flora of Catalonia (Northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3
    BOTANICAL CHECKLISTS Mediterranean Botany ISSNe 2603-9109 https://dx.doi.org/10.5209/mbot.63608 Checklist of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) Pere Aymerich1 & Llorenç Sáez2,3 Received: 7 March 2019 / Accepted: 28 June 2019 / Published online: 7 November 2019 Abstract. This is an inventory of the vascular alien flora of Catalonia (northeastern Iberian Peninsula, Spain) updated to 2018, representing 1068 alien taxa in total. 554 (52.0%) out of them are casual and 514 (48.0%) are established. 87 taxa (8.1% of the total number and 16.8 % of those established) show an invasive behaviour. The geographic zone with more alien plants is the most anthropogenic maritime area. However, the differences among regions decrease when the degree of naturalization of taxa increases and the number of invaders is very similar in all sectors. Only 26.2% of the taxa are more or less abundant, while the rest are rare or they have vanished. The alien flora is represented by 115 families, 87 out of them include naturalised species. The most diverse genera are Opuntia (20 taxa), Amaranthus (18 taxa) and Solanum (15 taxa). Most of the alien plants have been introduced since the beginning of the twentieth century (70.7%), with a strong increase since 1970 (50.3% of the total number). Almost two thirds of alien taxa have their origin in Euro-Mediterranean area and America, while 24.6% come from other geographical areas. The taxa originated in cultivation represent 9.5%, whereas spontaneous hybrids only 1.2%. From the temporal point of view, the rate of Euro-Mediterranean taxa shows a progressive reduction parallel to an increase of those of other origins, which have reached 73.2% of introductions during the last 50 years.

    THE VASCULAR FLORA OF THE NORTH CENTRAL TEXAS WALNUT FORMATION Rebecca K. Swadek Tony L. Burgess Texas Christian University Texas Christian University Department of Environmental Science Department of Environmental Science Botanical Research Institute of Texas TCU Box 298830 1700 University Drive Fort Worth, Texas 76129, U.S.A. Fort Worth, Texas 76107-3400, U.S.A. [email protected] [email protected] ABSTRACT Political boundaries frequently define local floras. This floristic project takes a geological approach inspired by Dalea reverchonii (Comanche Peak prairie clover), which is primarily endemic to glades of the Walnut Formation. The Cretaceous Walnut Formation (Comanchean) lies on the drier western edge of the Fort Worth Prairie in North Central Texas. Its shallow limestone soils, formed from alternating layers of hard limestone and clayey marl, support a variety of habitats. Glades of barren limestone typically appear on ridgetops, grassland savannas form on eroding hillslopes, and seeps support diverse hyperseasonal vegetation. Vouchers were collected from January 2010 to June 2012 resulting in 469 infraspecific taxa, 453 species in 286 genera and 79 families. The richest five plant families are Asteraceae (74 taxa), Poa- ceae (73), Fabaceae (34), Euphorbiaceae (18), and Cyperaceae (17). There are 61 introduced species. Results indicate floristic affinities to limestone cedar glades of the Southeastern United States, the Edwards Plateau of Central Texas, and calcareous Apacherian Savannas of Southwestern North America. RESUMEN Las fronteras políticas definen frecuentemente las floras locales. Este proyecto florístico toma una aproximación geológica inspirada en Dalea reverchonii (trébol de la paradera de Comanche Peak), que es primariamente endémico de los claros de la formación Walnut.

Micropropagation of 11 rare or endangered cacti species belonging to the subtribe Cactinae was achieved by rooting of proliferated axillary shoots. Shoot tip explants were obtained from seedlings of Escobaria missouriensis D.R. Hunt, E. robbinsorum (Earle) D.R. Hunt, Sclerocactus spinosior (Engelm.) Woodruff & L. Benson, and Toumeya papyracantha (Engelm.) Br. & Rose, and from mature plants of Mammillaria wrightii Engelm., Pediocactus bradyi L. Benson, P. despainii Welsh & Goodrich, P. knowltonii L. Benson, P. paradinei B.W. Benson, P. winkleri Heil, and S. mesae-verdae (Boissevain) L. Benson. Three or four species were used in each of a series of experiments investigating the effects of basal media and auxin and cytokinin types and concentrations on axillary shoot proliferation. Low or no auxin but moderate to high cytokinin concentrations were required for axillary shoot production. All species rooted spontaneously on hormone-free media; however, several species rooted better on media containing auxin. All species were re-established in the greenhouse. The propagation of native cacti is usually done with seed and painii, P. paradinei, P. winklerii, Toumeya papyracantha), rooted offshoots; however, conventional propagation methods threatened (E. robbinsorum, S. mesae-verdae), or endangered are inadequate for those species that exhibit no to few offshoots, (P.
