Although the writer has seen no specimens of M. papillata 

 from other localities, the following records may be cited from the 

 literature : 



Cuba: "ad terram in locis humidis prope S. Marcos," Ramon 

 de la Sagra, gemmiparous specimens (listed by Montague in 

 Ramon de la Sagra, Hist. Fis; Pol. y Natur. Cuba 9: 290. 1845). 



Martinique: without definite locality or collector's name 

 (hsted by Underwood in Bot. Gaz. 20:70. 1895); without 

 definite locality or date, A. Plee 182 1 (listed by Bescherelle in 

 Jour, de Bot. 7 : 193. 1893). 



Brazil: Rio Janeiro, C. Gaudichaud (listed, as M. platycne- 

 mos, in Freyc. Voy. Bot. 218. 1827) ; Minas Geraes, K. von 

 Martins (listed by Nees von Esenbeck in Naturg. Europ. Leberm. 

 4:109. 1838); "ad muros humidos aquaeductus, loco Corco- 

 vado dicto" near Rio de Janeiro, and "ad terram juxta flumen Rio 

 Negro", A. d'Orbigny (listed by Montague in D'Orbigny, Voy. 

 dans I'Amer. Merid. f : 397. 1839) . 



.Falkland Islands : without definite locality or date, C. Gaudi- 

 chaud (listed, as M. platycnemos, in Freyc. Voy. Bot. 218. 1827). 



The original M. papillata included two varieties, a. brasiliensis 

 and yS. italica. Nees von Esenbeck^^ soon showed, however, that 

 the second variety was a synonym of M. paleacea; he therefore 

 reserved the name M. papillata for the first variety, a course 

 which has been followed by subsequent writers. He was also 

 the first to recognize the fact that his Brazilian M. androgyna 

 belonged to M. papillata and to include M. platycnemos among 

 the synonyms of the same species. It is possible, however, that 

 M. platycnemos ought still to be maintained as a species, at least 

 in part. It was based on three specimens, the first from the 



Naturg. Europ. Leberm. 4:101. i{
