Summary

Psyllocarpus goiasensis J. H. Kirkbr. is an endemic species from the campo rupestre of Goiás. Psyllocarpus laricoides Mart. & Zucc. var. γ longicornu K. Schum., formerly under the synonymy of P. laricoides, is treated here as a new synonym of P. goiasensis. A second-step lectotype is designated for this variety. The first illustration and photographs of P. goiasensis, as well as a distribution map and comments on its ecology are presented. This species is assessed as Endangered (EN) under the range size (B) criterion of the IUCN.
