A striking species (with somewhat the habit of a Mikania) errone- 
ously placed by DeCandolle in his § Cylindrocephala, and by Schultz, 
who perhaps knew the plant only from description, similarly referred 
to Osmia, from which of course it is clearly distinguishable both by 
its campanulate more loosely imbricated involucre and ‘its hairy 
receptacle. It is unfortunate that the data of collection appear to 
have been lost on both occasions on which the plant has been secured.
