Trema domingensis rises like a phoenix from the ashes of T. integerrima: A reassessment of the entire-leaved species of Neotropical Trema (Cannabaceae). The genus Trema (Cannabaceae) suffers from a historical lack of taxonomic study. We sought to ameliorate this by studying the genus from phylogenetic and morphological perspectives. This study focuses on the three entire-leaved species of Neotropical Trema (T. integerrima (Beurl.) Standl., T. domingensis Urb., and T. laxiflora Lundell). We resolve three problems concerning these species: 1) Phylogenetic and morphological patterns show that they are best treated as a single species. 2) The date of publication gives priority to the name T. integerrima, as the basionym was published in 1856. However, the type specimen is not a Trema. Thus, the species becomes T. domingensis. 3) The types of T. domingensis are mixed collections. We provide a historical review to understand how these problems arose and persisted unnoticed for decades. Log in to add this item to your schedule
