Abstract

A new species in the Saxifragaceae, Heuchera woodsiaphila is described from the Capitan Mountains of Lincoln County, New Mexico. This species is similar to those of Heuchera section Holochloa subsection Cylindricae but is highly disjunct from described members of the subsection. Heuchera woodsiaphila is readily distinguished from other Heuchera in the area by its greenish-white to cream apetalous flowers with erect sepals 2.75-3.75 mm long. It is known from only small, scattered populations on forested granitic talus on the north and northeastern sides of Capitán Peak, between 2,550 and 2,900 m in elevation. Se describe una especie nueva, Heuchera woodsiaphila (Saxifragaceae) de las Capitán Mountains en Lincoln County, Nuevo México. Esta especie es similar a las de Heuchera sección Holochola subsección Cylindricae, pero geográficamente está muy alejada de miembros de la subsección descritos anteriormente. Heuchera woodsiaphila se distingue fácilmente de otras Heuchera en la región por sus flores apétalas de blanco-verdosas a ocroleucas con sépalos erectos de 2.75 a 3.75 mm de largo. Se conoce sólo de dos colectas en taludes graníticos de bosque en las laderas norte y noreste de Capitán Peak, en elevaciones de 2,550 a 2,900 m.
