El endemismo en la flora fanerogámica de la Mixteca Alta, Oaxaca‑Puebla, México
The Mixteca Alta region is located at the junction of NW part of the state of Oaxaca and the S of Puebla. It is covered primarily by Pinus and Quercus forest and chaparral with small areas of tropical deciduous forest and cloud forest. Its flora is estimated in 1550 indigenous species; 163 (10.5%) o...

| description | The Mixteca Alta region is located at the junction of NW part of the state of Oaxaca and the S of Puebla. It is covered primarily by Pinus and Quercus forest and chaparral with small areas of tropical deciduous forest and cloud forest. Its flora is estimated in 1550 indigenous species; 163 (10.5%) of them are endemic, 97 (59.5%) of these are restricted to the Mixteca Alta, 50 (30.7%) extend their distribution area farther west into Oaxaca, and 16 (9.8%) farther east into Guerrero. Thirty-four families and 92 genera present endemic taxa. Ainea (a monotipic genus) is endemic to Mixteca Alta, while Fosteria, Gibasoides and Pseudocranichis extend lightly outside this limit. The life forms in the endemic element consist of 52% herbaceous plants, 20% succulents, 17% shrubs, 4% climbers, 6% of creeping and epiphytes, and 1% trees. Given our present knowledge of the flora we estimate that about 15-20% of the species are still uncollected. In this paper a list of the endemic taxa is included, with information about their distribution, life forms and the political districts in which they occur. |

La Mixteca Alta es una región montañosa, ubicada al NO del estado de Oaxaca y S de Puebla. La dominan principalmente bosques de Pinus y Quercus, diversos tipos de matorrales y pequeñas áreas con bosque tropical caducifolio y bosque mesófilo de montaña. En el inventario de su flora fanerogámica se reconocen hasta el momento 1550 taxa nativos, 163 (10.5%) de los cuales son endémicos. Noventa y siete de este total (59.5%) son exclusivos de la Mixteca Alta, 50 (30.7%) extienden su área de distribución hacia el centro del estado de Oaxaca y 16 más (9.8%) hacia Guerrero. Treinta y cuatro familias y 92 géneros presentan algún taxon endémico. El género Ainea (monotípico) es endémico a la Mixteca Alta, mientras que Fosteria, Gibasoides y Pseudocranichis rebasan un poco sus límites. Las formas de vida representadas en las especies endémicas corresponden a las plantas herbáceas (52%), suculentas (20%), arbustos (17%), trepadoras (4%), rastreras y epifitas (6%) y árboles (1%). Con el conocimiento actual de la flora se estima que aún quedan por localizarse entre 15 y 20% de las especies. En este trabajo se incluye la lista de los taxa endémicos, con datos sobre su distribución, sus formas de vida y los distritos políticos donde se concentran.
