Typification, geographical expansion and conservation of Catasetum rooseveltianum (Orchidaceae, subtribe Catasetinae), a species revealed by the Rondon Commission in the Early 20th century
摘要
Based on literature survey, protologue analysis, field collections, and examination of herbarium specimens, we propose a lectotype for Catasetum rooseveltianum. The study also extends the geographical distribution of this species into the northern part of Brazil. An emended description of the taxon is provided together with taxonomic and ecological notes, a distribution map, and a preliminary conservation assessment.
