Economic Botany 55 : 2001. Information on richness of plant resources, and their forms of use and management in the biosphere reserve Tehuaccin-Cuicatldn, Mexico is analyzed. This 10 000 km 2 region hosts nearly 2700 vascular plant species, and it is acknowledged as one of the arid areas with the highest floristic diversity in North America. The seven indigenous ethnic groups that live in this region have cultural roots that date back almost 10 000 years. Based upon ethnobotanical and floristic studies, as well as bibliographical sources, a total of 808 useful plant species were identified, most of them (90%) being native, and 44 species being endemic to the region. A total of 681 species are wild plants, 109 are weeds and ruderal plants, and 86 are domesticated crops. However, it was noted that considerable overlap exists between the species of these 3 categories. For example, while wild and ruderal plants (706 species) are foraged by both humans and domestic animals, 59 species of this group are also managed in situ. On the other hand, 168 wild, ruderal and domesticated species are cultivated. The Tehuacdn-Cuicatldn Valley is one of the richest regions of Mexico in plant resources. Local knowledge on use and management of plants is a valuable source of information for designing conservation and social development strategies for the biosphere reserve.

Esehweilera mexieana, a new species of Lecythidaceae from the Uxpanapa rain forests of southeastern Veracruz and adjacent Oaxaca, represents a new family for the Mexican flora. It is a locally common canopy tree in an area considered to have served as a refuge for rain forest species during the Pleistocene. Its closest relative is E. hondurensis, a species known only by one fruiting collection. Eschweilera is the largest (ca 90 species), most complex, and most poorly collected genus of neotropical Lecythidaceae. Complete collections of vegetative structures, flowers, fruits, seeds, and seedlings of all species over a much wider range are needed before a satisfactory classification of this genus can be prepared. However, the Central American species of Eschweilera provide an example of how intensified collecting programs can add to our knowledge of tropical floras. Woodson (1958) cited only four species of Eschweilera from Panama, whereas today we know of at least 14 from that country. There are only three known species from Costa Rica, one from Honduras, and now, a single species from Mexico. It is noteworthy that E. mexicana is locally abundant, but up to now it had not been collected. This is the first confirmed report of a naturally occurring Lecythidaceae in Mexico. Eschweilera mexieana Wendt, Mori & Prance, sp. nov. (Figs. 1 & 2) Ab E. hondurensis foliis coriaceis, fructibus majoribus (2.5-5 • 4-6.5 nec 1.5-3.5 x 2-4 cm) sine pedicello persistentis et seminibus plerumque hemisphaericis vel triangularibus (nec rotundatis) in sectione transversalis differt.

The names Opuntia bulbispina, O. clavata, O. emoryi and O. grahamii, originally proposed by George Engelmann between 1848 and 1856, are reviewed and typified after new findings of previously unknown voucher specimens. Original materials collected by some of the collaborators employed by Engelmann during the Mexican Boundary Survey were discovered in a loan from the Torrey Herbarium at the New York Botanical Garden (NY). Many of the materials include fragments of stems and fruits, and others include only sectioned flowers and some seeds. Particularly good descriptions of the species here concerned were published in Engelmann's "Synopsis of the Cactaceae" in 1857, and exceptional illustrations were produced by Paulus Roetter and printed in "Cactaceae of the Boundary" in 1859. The problems surrounding some previous typifications of these names range from typification of joint lectotypes to illegitimate typifications of illustrations when original material was known to exist. The materials selected for typification were collected by the Mexican Boundary Survey and are lodged at the herbaria of the Missouri Botanical Garden (MO) and the New York Botanical Garden (NY); some are illustrations published by Engelmann. resumen: Los nombres de Opuntia bulbispina, O. clavata, O. Emoryi and O. grahamii originalmente propuestos por George Engelmann entre 1848 y 1856 son tipificados después de descubrir nuevos materiales de herbario previamente desconocidos. Los materiales originales colectados por algunos de los colaboradores de Engelmann durante el Estudio de la Frontera Mexicana han sido descubiertos en un préstamo del Herbario Torrey del Jardín Botánico de Nueva York (NY). Los ejemplares encontrados incluyen fragmentos de tallos y frutos así como flores seccionadas y algunas semillas. Las descripciones completas de estas especies fueron publicadas por Englelmann en la "Sinopsis de las Cactaceae" en 1857, e ilustraciones excepcionales fueron elaboradas por Paulus Roetter e incluidas en el reporte "Cactaceae de la Frontera" en 1859. Los problemas relacionados con estas tipificaciones oscilan desde tipificaciones de lectotipos conjuntos a tipificaciones ilegítimas de ilustraciones cuando se conocía la existencia de materiales originales. Los materiales seleccionados fueron colectados en el Estudio de la Frontera Mexicana y se encuentran actualmente depositados en el Jardín Botánico de Nueva York (NY) y el Jardín Botánico de Misuri (MO) y las ilustraciones fueron incluidas por Engelmann en su reporte sobre las Cactaceae de la Frontera de 1859.

Los huertos familiares son micro-ambientes que contienen una gran diversidad de especies vegetales y animales de utilidad humana. El objetivo del presente estudio fue determinar la diversidad de usos y el papel de las plantas útiles aprovechadas del Ejido Sinaloa 1 a sección del municipio de Cárdenas, Tabasco, México. Se realizaron recorridos de campo de febrero de 2009 a junio de 2010, en los cuales se registraron las especies vegetales, los usos y partes empleadas. Se aplicó una entrevista semiestructurada mediante una metodología etnográfica en 73 hogares. Los entrevistados reconocieron 93 especies botánicas que fueron integradas en 14 categorías de uso como: medicina, alimentación, ornamental, leña, barrera rompe viento, construcción, cerco vivo, ritual mágico-religioso, sombra, tendedero, envoltura, instrumento de trabajo, humo (para alejar insectos) y saborizante. Las partes más usadas las constituyeron los frutos, las hojas y la planta completa. En cuanto a la forma biológica de las especies vegetales, los árboles fueron los más usados, seguido de las hierbas y los arbustos. Se obtuvo un índice de diversidad de mención de H'= 4.00 y valores del índice de fidelidad entre 13% y 89%.

Plant catalogues are basic to propose and manage natural protected areas. Through those censuses plans and conservation strategies are developed, plus comparisons can be made over time. Updated floristic listings are urgent in tropical forests due to the threats to their biodiversity. Objective. Present a structured listing by family, genus and species, which quantifies the hierarchical relations of genera-species and familygenera while arranging life-forms and including species with endangered status recorded in national (NOM-059 SEMARNAT 2010) and international (Red list, UICN) legislation of woody and semi-woody plants from dry and semi-humid forest from the Área de Protección de Flora y Fauna Meseta de Cacaxtla, Sinaloa, México (APFFMC). Methodology. Published studies about the site were reviewed, selecting the indigenous species with secondary growth, excluding the invasive, naturalized, cultivated, ornamental ones, collating different online sites, specialized bibliography and consulting specialists. Regarding the nomenclature different sources and databases were employed. Through field trips, the presence of taxa was corroborated and new registers were included. The listing was sorted alphabetically. Results. 60 families, 223 genera and 389 species were recorded. Fabaceae was the family with the highest taxa richness, with 44 genera and 75 species, followed by Malvaceae (19/31), Euphorbiaceae (12/34), Asteraceae (10/17), Cactaceae (9/21) and Apocynaceae (8/10). A low number of 13 genera and 12 families gathered five or more species and genera respectively. On the other hand, a high quantity of 210 genera and 48 families presented four or less taxa. The most diverse genera were Croton (12 species), Bursera (8), Solanum (7), Ficus and Randia (6); Opuntia, Merremia, Euphorbia, Lonchocarpus, Mimosa, Senna, Jatropha and Sideroxylon (5). The tree category grouped 146 species, followed by shrub (114), sub-shrub (54), vine (51), succulent and semi-succulent (21) and parasitic (3). According to the NOM 059 SEMARNAT-2010 endangered species list, five species were included in the Amenazadas (A) category and two Sujetas a protección especial (Pr). The red list (UICN) comprehended 173 species for the Natural Protected Area (ANP). In the Least concern category (LC) 155 taxa were counted, Near threatened (NT) with four, Vulnerable (V) seven and Endangered (EN) again seven. Implications. A renewed listing of alien, native, woody and semi-woody species from dry and semi-humid forests of the APFFMC, is crucial for its contribution to a proper management and decision taking in the ANP. 94 taxa names were updated. At family level, the inclusion of Sterculiaceae into Malvaceae was the most significant change. Conclusions. The taxonomic richness concentrated inside the APFFMC, whose surface is inferior to 1% of the state, oscillates

Trees or tree-like plants are defined here broadly as perennial, self-supporting plants with a total height of at least 5 m, without considering ascending leaves or inflorescences, and with 1 or several erect stems with a diameter of at least 10 cm. In this third contribution of the taxonomic compilation of Mexico's native tree species, 271 species are presented: 27 in the family Apocynaceae (26% endemic), 63 in the Cactaceae (79%), 17 in the Ebenaceae (35%), 123 in the Fagaceae (60%), and 41 in the Sapotaceae (22%). Several cactus genera are endemic to Mexico, notably Neobuxbaumia with 10 species and heights up to 22 m. The oak genus Quercus with 122 species is the most species-rich genus of Mexican trees. Several species are reported to reach heights of 60 m (Aspidosperma desmanthum, Quercus benthamii, Q. corrugata, and Manilkara chicle). All species are listed in an appendix, including the original publication, references of taxonomic revisions, in some cases synonyms, existence of subspecies or varieties, maximum height in Mexico, and the indication if the species is endemic to Mexico.
