Typus: GUYANA : British Guiana , Potaro River below the Kaieteur , IX-X.1881 , Jenman 959 (holo-: K [ K000173648 ] image seen) . Notes. – This species is found in the Guianas and Amazonian Venezuela , Ecuador , Peru , and northern Brazil ( TAYLOR, 2005 ). See TAYLOR (2005) and DELPRETE & KIRKBRIDE (2015) for synonymy. DELPRETE & KIRKBRIDE (2015) reported that this species is found “throughout Brazil ” but it seems to be restricted to the Amazon basin. Eumachia astrellantha has often been confused with E. chaenotricha , which is found widely in eastern and southeastern Brazil .
