Abstract
In this work, Myrcia urquiolae, a new endemic species of the subspinous xeromorphic scrub on serpentinites of the Sierra de Nipe, is described and the geographical distribution of its only population is presented. Myrcia urquiolae belongs to the Myrcia sect. Myrcia, of whose other species in Cuba is distinguished by its linear leaves with a strongly twisted margin. Based on field exposures, M. urquiolae is categorized as Critically Endangered according to IUCN criteria.
