“…Two genera stand out owing to their elevated number of species: Echeandia and Tigridia, both distributed in the New World and with their greatest diversity in Mexico (Rodríguez & Ortiz-Catedral 2013, Munguía-Lino et al 2015. Of the ten Mexican endemic geophyte genera, five belong to Asparagaceae (Behria, Bessera, Dandya, Jaimehintonia, Petronymphe) and are members of the Milla clade.…”

Background: Geophytes, plants with underground perennating organs that lose their aerial organs annually, are able to survive in harsh habitats. This life form is common in the monocots that inhabit Mediterranean climates around the world. In Mexico only the northern area of Baja California has this type of climate. Hypothesis: In this study, we recorded the species and distribution of Mexican geophyte monocots to pinpoint diversity hotspots. Our hypothesis is that the highest diversity of geophytes will be found in biogeographic areas with complex topography and seasonal climate not only in the north of the Baja California Peninsula. Data description: Records of geophytes were taken from different sources, collections, taxonomic references and diversity databases. Geophyte locations were mapped in the context of biogeographic and protected areas. Climate preferences were estimated using bioclimatic variables and by a Principal Component Analysis we identified the most significant variables explaining distribution of geophytes. Results: The Mexican geophyte flora is composed of 476 species, approximately 10 % of the total diversity of monocots. Echeandia and Tigridia were the two most diverse genera. This flora is dominated by the taxa of Orchidaceae, Asparagaceae and Iridaceae, and ten small endemic genera were recorded. Geophyte diversity was highest in two biogeographic provinces: the Trans-Mexican Volcanic Belt and the Sierra Madre del Sur, in dry forests such as oak-pine, seasonally dry tropical forests and semi-arid shrubby vegetation. Three bioclimatic variables: temperature seasonality, annual precipitation and precipitation of the wettest quarter resulted significant for understanding distribution of geophytes. Conclusions: Areas sustaining a high diversity and endemism of geophytes are located in the Mesoamerican Biodiversity Hotspot, in unprotected and threatened areas. Our results suggest that geophytes are able to grow in different climates but in areas with marked temperature seasonality and variation of annual precipitation.

Esta forma de vida es común en las monocotiledóneas que habitan en áreas con clima Mediterráneo en todo el mundo. En México únicamente el área norte de Baja California tiene este tipo de clima. Hipótesis: En este estudio se registra la diversidad y endemismo de las geofitas monocotiledóneas en México para identificar áreas con alta diversidad. Nuestra hipótesis plantea que la más alta diversidad de geofitas monocotiledóneas se encontrará en provincias biogeográficas con topografía compleja y variados tipos de climas y no solamente en Baja California.

“…Se siguió el concepto morfológico de especie, con base en los postulados de Crisci (1994) (Reveal & Chase 2011), ya que algunos autores lo ubican en las familias Asphodelaceae (Dahlgren & Clifford 1982), Anthericaceae (Dahlgren et al 1985, Chase et al 1995, López-Ferrari & Espejo Serna 1995, Conran 1998, Cruden 1999, 2009, Gereau 1999, Stevenson 2004, Campbell 2008, Martínez Domínguez 2009, Takhtajan 2009, Santiana & Suin 2011, Rodríguez & Ortiz-Catedral 2013, Liliaceae (Cruden 1981, 1986, 1989, 1993, 2001, 2002, Sklenář et al 2005, Aphyllanthaceae (Thorne 1992) o Agavaceae (APG II 2003). Al respecto, se puede reevaluar la condición de disyunción de algunas especies, ya que realmente la disyunción la "presentan" las áreas naturales en las cuales se establecen dichas especies, en este caso, áreas principalmente secas y bosques secos tropicales, cuya representatividad y expresión se da en varios países americanos y sin contigüidad ambiental, valga decir, separados por otros tipos de formaciones vegetales.…”

“…Echeandia Ortega es un género nativo del Nuevo Mundo, distribuido desde el sur de los Estados Unidos de América (Arizona, Nuevo México y Texas) hasta el sur de Perú (Cruden 2009), del cual se conocen entre 78 y 90 especies (Cruden 1994, 2002, 2009, Mabberley 2008, Martínez Domínguez 2009, Rodríguez & Ortiz-Catedral 2013, muchas de ellas están principalmente representadas en México, en donde habitan entre 59 y 69 especies (Cruden 2009, Rodríguez & OrtizCatedral 2013, de las cuales 62 son endémicas (Rodríguez & Ortiz-Catedral 2013), mientras que en Sudamérica se encuentran sólo ocho especies y de éstas, cinco son endémicas (Cruden 2009). Este género es propio de áreas abiertas (pastizales, herbazales, arbustales) y de bosques abiertos, generalmente de regiones secas por encima de los 500 m de altitud, tanto de áreas conservadas como alteradas (véanse Cruden 1994(véanse Cruden , 2009).…”

Caldasia 37(1): 61-71. 2015 RESUMEN Echeandia flavescens (Asparagaceae) se registra por primera vez para Sudamérica (Colombia y Venezuela), mientras que Echeandia denticulata y Echeandia durangensis se reducen a la sinonimia de Echeandia flavescens. Echeandia flavescens es una entidad poliploide, por lo que exhibe una morfología muy variable, así como una amplia distribución geográfica. Se discute la disyunción geográfica de esta especie, se entregan datos sobre su ecología y posibles polinizadores en Colombia y se presentan algunas relaciones con especies morfológicamente afines.Palabras clave. Anthericaceae, Asparagaceae, Disyunciones geográficas, Echeandia, Plantas neotropicales. ABSTRACTEcheandia flavescens (Asparagaceae) is reported for the first time for South America (Colombia and Venezuela), while Echeandia denticulata and Echeandia durangensis are synonymized under Echeandia flavescens. Echeandia flavescens is a polyploid taxon exhibiting a highly variable morphology and broad geographic distribution. The disjunct distribution of this species and morphological relationships with similar species are discussed. Information on the ecology of the species and possible pollinators in Colombia are provided.

“…The genus ranges from the southwestern United States of America to southern Peru, but several species have narrow geographic ranges. The number of species is increasing since more areas are being explored and detailed analyses are made based on herbarium specimens (Cruden, 1999;López-Ferrari et al, 2002;Rodríguez and Ortiz-Catedral, 2013;Rodríguez and Ortiz-Brunel, 2019). Both field and herbarium work led us to name and describe a new species, which are the objectives of this study.…”

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). Here, we name and describe a new species of Echeandia found along the TMVB in the states of Puebla and Tlaxcala.Methods: Field work and herbarium revision led us to discover a new species of Echeandia. The morphological description and illustration were based on eight voucher specimens plus living plants from two populations. Moreover, we compared the morphology of the new taxon with that of E. michoacensis and E. robusta. Lastly, we assessed its conservation status by calculating its extent of occurrence (EOO) and its area of occupancy (AOO), using the GeoCAT tool and based on the IUCN Red List categories and criteria.Key results: Echeandia cholulensis is a new species from Mexico. The new taxon includes robust plants characterized by root-thickenings distant from the corm; lanceolate, undulate, and glaucous leaves; ascending flowers with white tepals; clavate and muricate filaments, and free anthers with longitudinal dehiscence. Until now, it is known from three populations in central Mexico in the states of Puebla and Tlaxcala.Conclusions: Along the TMVB, volcanism has created topographic and climatic variation favoring speciation and persistence. The discovery and morphological description of Echeandia cholulensis exemplifies this observation. Furthermore, botanical exploration and herbaria revisions might discover new species that would increase the great plant diversity of the TMVB.
