12. Stigmatopteris rotundata (Willd.) C. Chr. Bot. Tids. 29: 297 fig. 2. 1909. 

 Area: Lesser Antilles from Montserrat to Trinidad. South Brazil. 

 Nephrodium Imragannm Hk. spec. fil. 4: 86. 1862 from Dominica, Imray (Kew!) 

 is exactly this species. The specimen is absolutely exindusiate. 



13. St. Carrii (Bak.) C. Chr. 1. c. 298 fig. 3. 



Area: Brazil. 



The type-specimen from Rio, leg. Carr (Kew!) shows that I have rightly 

 understood this species, which is perhaps not specifically different from S. rotundata. 



Aspidium brachijnevron Fée, Cr. vase. Brés. 1: 133. 1869 from Bahia, Blanchet, 

 is probably this species. 



14. St, tijuccana (Raddi) C. Chr. 1. c. 298, fig. 4.

 Dryopteris Ulei C. Chr. Ind. 299 from S. Catharina, Ule nr. 70, is probably a form 

 of this species. 



16. St. nephrodioides (Kl.) C. Chr. 1. c. 299, fig. 8. 

 Area: Venezuela Costa Rica.
