The plants with the ticket " Stuhlmann, 93," are by some error in distribution 

 marked Rhyncospora echinophora, K. Schum. ; but 1 have not found where that 

 Mhyncospora is published. In Cameron, 89, the stems exceed 5 it. in hcighi ; the 

 heads are young and I do not see how they differ from young heads of K. melano- 

 sperma.
