“…En este trabajo se ratificó que el género Phaseolus es un grupo monofilético que se subdivide en dos linajes principales: uno incluye a las especies P. La especie P. rotundatus, endémica del occidente de México, se considera en peligro de extinción y las pocas poblaciones conocidas a la fecha se localizan en áreas naturales no protegidas como Tepatitlán de Morelos, Jalisco (Salcedo et al, 2009). La colecta de los especímenes de esta y otras especies fue difícil debido principalmente a la expansión creciente de los asentamientos humanos y la consiguiente afectación de los hábitats naturales de las especies silvestres de Phaseolus (Acosta-Diaz et al, 2015;Baez-González et al, 2019). Las especies de Phaseolus agrupadas en el segundo clado de los árboles filogenéticos corresponden, en general, a sitios geográficos de recolección ubicados hacia el Este de México.…”

Podopterus mexicanus Humb. & Bonpl. Polygonaceae. "Rompe capa". Árboles o arbustos de 1.5-6.0 m de altura, ramas con espina terminal, braquiblastos, hojas fasciculadas, flores blancas a verdosas en fascículos, y frutos cubiertos por el perianto externo que forma alas delgadas y largamente decurrentes hacia el pedicelo. Crece en bosques tropicales caducifolios y bosques espinosos, sobre suelo rocoso negro derivado de rocas ígneas. En elevaciones de 550-760 m. Florece de abril a mayo y fructifica de junio a septiembre.

“…This reclining vine with light purple standard and white wings (Fig. 4) is considered as endemic because only a few populations are known to date, from pine-oak forests of Santiago and Cola de Caballo south of Monterrey in Nuevo León and neighboring Tamaulipas, Mexico, at 1500-1900 m (also noted by Acosta-Díaz et al 2015).…”

“…This species, reference of the Bracteati, grows in the now much logged old-growth pine forests, endemic of the volcanic axis of SW Guatemala at 2200-3000 m. It is not reported in the list of "Vascular Plants of the Americas" (Tropicos 2020). In addition to the type, five other populations have been reported recently, lowering the risk of extinction in the immediate future (Acosta-Díaz et al 2015 In the large series of "Flora Texana exsiccata. 367.…”

“…With the specimens available, field work and the cultivation of several materials of this section, the author now considers race A corresponding to the species described by Hermann, and race B to P. albiflorus. A couple of populations have been sampled recently (Acosta-Díaz et al 2015).…”

“…Phaseolus novoleonensis Debouck (2006: 105) A member of the Coriacei with rounded leaflets. One more population could have been found recently (Acosta-Díaz et al 2015); the species is however considered as endangered because of its extremely small range (Acosta-Díaz et al 2019).…”

This work presents an updated list of the species belonging to the genus Phaseolus following its definition of 1978; it is the outcome of the study of eighty-six herbaria and forty-one explorations in the field in the period 1978–2019. There are currently eighty-one species, all of them native to the Americas, most of them distributed north of Panama (the genus is a migrant into South America), and half of them being known by very few records. They thrive in warm to mild temperate, seasonally dry, open forest, with rains under favorable temperature, from sea level up to 3,000 m. The recent increase in the number of recognized species is due to the endemic ones; this in combination with few unclassified specimens may indicate that the total number of species is not final yet, and that field work will be rewarding.

Despite its economic, social, biological, and cultural importance, wild forms of the genus Phaseolus are not well represented in germplasm banks, and they are at great risk due to changes in land use as well as climate change. To improve our understanding of the potential geographical distribution of wild beans (Phaseolus spp.) from Mexico and support in situ and ex situ conservation programs, we determined the climatic adaptation ranges of 29 species and two subspecies of Phaseolus collected throughout Mexico. Based on five biotic and 117 abiotic variables obtained from different databases—WorldClim, Global‐Aridity, and Global‐PET—we performed principal component and cluster analyses. Germplasm was distributed among 12 climatic types from a possible 28. The general climatic ranges were as follows: 8–3,083 m above sea level; 12.07–26.96°C annual mean temperature; 10.33–202.68 mm annual precipitation; 9.33–16.56 W/m2 of net radiation; 11.68–14.23 hr photoperiod; 0.06–1.57 aridity index; and 10–1,728 mm/month of annual potential evapotranspiration. Most descriptive variables (25) clustered species into two groups: One included germplasm from semihot climates, and the other included germplasm from temperate climates. Species clustering showed 45% to 54% coincidence with species previously grouped using molecular data. The species P. filiformis, P. purpusii, and P. maculatus were found at low‐humidity locations; these species could be used to improve our understanding of the extreme aridity adaptation mechanisms used by wild beans to avoid or tolerate climate change as well as to introgress favorable alleles into new cultivars adapted to hot, dry environments.
