are many major floral differences to separate the two con- 
cepts. It also looks vegetatively rather like Aristolochia 
mutensis O. C. Schmidt, but the lip of the flower is 
very different. 
Of interest as a peculiarity of -fristolochia georgica is 
the curious dense, golden, tomentose apicule terminating 
the broad, oblong, rounded lip. The species is unusual in 
the Mustipulatae in having amany-flowered inflorescence.
