This species was previously known to occur in Brazil only , ana tne 

 original plant was gathered by Swainson near Rio de Janeiro, according 

 to Hooker (Muse. Exot. t. 128). Hooker's Herbarium, however, 

 afEords reason for the belief that the original locahty was Bahia. Ihe 

 African plant appears to differ from the Brazilian as redescribed by 

 C Mueller (Synops. I. p. 761) in the lighter colour (yellowish brown), 

 more laciniate base and less rough (merely scab-ous) apex of the 

 calyptra.
