Conservation status the genus Hampea (Malvaceae: Gossypieae) in Mexico
<p><strong>Background. </strong>The genus <em>Hampea</em> (Malvaceae: Gossypieae) has 21 reported species and occurs in Mexico, Central America and Colombia. Mexico has eleven species, of which seven are endemic. <em>Hampea</em> is of special conservation interest because its members are wild relatives of cultivated cotton and several species are apparently threatened by anthropogenic activities.</p><p><strong>Questions: </strong>What is the conservation status of species of <em>Hampea </em>in Mexico?</p><p><strong>Study site and years of study:</strong> Observations were made in the field during 1991-1995, 2012 and 2016 in southern Mexico. Specimen data was obtained from the CONABIO data base and from national and international herbaria from 2014-2016.</p><p><strong>Methods. </strong>The conservation status of species of <em>Hampea</em> in Mexico was evaluated using criteria given in the Methods of the Evaluation of Risk of Extinction of Plants (MER-Plantas) (NOM-059-SEMARNAT-2010). The potential distribution was calculated using Maximum Entropy Algorithm and biological data for species were obtained from literature and field observations.</p><p><strong>Results. </strong>Seven species of the genus <em>Hampea </em>were considered to be in a category of risk under the MER-Plantas criteria. <em>Hampea montebellensis</em>, <em>H.</em> <em>breedlovei</em>, and <em>H.</em> <em>longipes </em>were categorized as “at Risk of Extinction,” (En Peligro de Extinción ); <em>H.</em> <em>latifolia </em>was categorized as “Threatened” (Amenazada) and <em>H. stipitata, H. mexicana, </em>and <em>H. tomentosa </em>categorized as “Subject to Special Protection” (<em>Sujeto a Protección Especial</em>).</p><strong>Conclusions.</strong> The species <em>H.</em> <em>breedlovei</em>, <em>H. montebellensis</em>, <em>H. longipes, H</em><em>.</em> <em>latifolia,</em> <em>H.</em> <em>mexicana, H. stipitata </em>and <em>H. tomentosa </em>need to be included in <em>ex situ </em>and <em>in situ </em>conservation programs.
