It is known only from the granitic rock crevices of Cerro de la Calavera, and others in the vicinity, in the southern Cape region mountains. This species is characterized by its suffrutescent habit, as well as by its densely tomentose indumentum, which on its leaves is manifested by different color shades on the upper and lower sides. We present a detailed botanical description, illustrations, and photographs of this new taxon. Since this species seems to be linked to special edaphic conditions, we provide some locations where it might also be found with additional field exploration. The exact taxonomic placement of this new taxon within the genus Eriogonum is still in question and future cytogenetic and molecular data might help to address this problem.]]></p></abstract>
<abstract abstract-type="short" xml:lang="es"><p><![CDATA[Resumen Describimos e ilustramos Eriogonum calaverense, una especie nueva de Polygonaceae del extremo sur de la península de Baja California, México. Crece solamente en las grietas de la roca granítica en el cerro de la Calavera y otros cerros aledaños, en las montañas sur de la región de Los Cabos. Esta especie se caracteriza por su hábito leñoso en la base, así como por su indumento densamente tomentoso, que en sus hojas se manifiestan en diferentes tonalidades en el haz y el envés. Se presentan la descripción, ilustraciones y fotografías detalladas. Debido a que este taxón nuevo parece estar vinculado a condiciones edáficas particulares, se presentan algunos sitios adicionales donde podrían encontrarse más poblaciones con una mejor exploración de campo. La ubicación taxonómica exacta del nuevo taxón dentro de Eriogonum es todavía incierta y futuros datos citogenéticos y moleculares servirán para analizar este problema.]]></p></abstract>
