Gypsum soils occur around the world, mainly in arid regions. These harsh environments promote unusual flora with high degrees of endemism. Mexico has extensive gypsum outcrops, but their flora has been poorly studied. However, the highest species richness and endemism are expected to be concentrated in Mexico's northern dry regions. To promote the...

Plant recruitment interactions (i.e., who recruits under whom) between 3,318 vascular plant species across the globe

Flora de Jalisco y áreas colindantes, Fascículo 29: Fouquieriaceae

Background: The Mammillaria series Stylothelae (Cactaceae) includes 16 taxa distributed mostly among the limits of the Chihuahuan Desert (CD) with the Sierra Madre Oriental and the Transmexican Volcanic Belt (TVB). In Jalisco, four pink flowered species occur at the southwestern end of the CD where it meets the TVB. The boundaries and recognition o...

Antecedentes: La Sierra Madre Oriental es una Provincia Fisiográfica ubicada en el noreste de México con características geológicas, climáticas y edáficas distintivas. La flora de esta región aún no ha sido inventariada en conjunto. Preguntas: ¿Cuál es la diversidad florística de la Provincia Fisiográfica de la Sierra Madre Oriental? ¿Cuál es la a...

Background and Aims: The genus Echeandia (Asparagaceae) characterizes the Mexican geophyte flora. The group is exclusive of the Americas and includes 85 species. In Mexico, there are 74 species, of which 63 are endemic; however, the species richness is concentrated in the Mexican Transition Zone, including the Transmexican Volcanic Belt (TMVB). Her...

Echeandia (Asparagaceae) is an American genus of herbaceous geophytes. Its distribution is heterogeneous but concentrates along the Mexican Transition Zone (MTZ). We analyzed the species richness distribution and endemism of the group. We compiled a data base of 2,078 records obtained by revision of herbarium specimens, scientific publications, and...

Bessera (Asparagaceae: Brodiaeoideae) is a genus endemic to Mexico. It currently has two described species: B. elegans with a wide geographic distribution from Durango and Sinaloa in the Sierra Madre Occidental, across the Transmexican Volcanic Belt to Oaxaca in the Sierra Madre del Sur, and B. tuitensis which is endemic to the Sierra del Cuale in...

Chusquea is the richest genus of woody bamboo worldwide, with 191 described species distributed from Mexico, the Antilles, and Central America to southern South America. Mexico has 22 described species distributed along the Trans-Mexican Volcanic Belt, Sierra Madre del Sur, Sierra Madre Oriental and Chiapas Highlands. Two of the five subgenera reco...

Echeandia jaliscensis is described from the municipality of Mixtlán, Jalisco, in western Mexico. The new species has white tepals, scaled filaments and connate anthers. Morphologically, it may be confused with E. pringlei and E. nayaritensis. It differs from E. pringlei mainly by having wider and entire leaves. Also, E. jaliscensis has longer tepal...

Otatea, with 12 described species, is the second most diverse genus in the subtribe Guaduinae. Eleven species of Otatea occur in Mexico, of which 10 are endemic. The Mexican Otatea species grow in tropical dry forest, the ecotone between tropical dry forest and oak forest, cloud forest, humid oak-pine forest, and xerophilous scrubs. Here, we descri...
