62. D. physeniatioides (Kuhn et Christ) C. Chr., Revision nr. 31. 

 Area: San Domingo. 



63. D. opposita (Vahl) Urban; C. Chr. Revision nr. 25 fig. 15, Iß; Smiths. Misc. 



Coll. 53: 375. 



Area. Type: Lesser Antilles, common. Different forms occur in Jamaica, 

 Cuba, Florida, Mexico, Colombia— Peru. var. riimloriim (Raddi): Southern Rrazil. 



I now regard D. amphioxypteris (Sod.) C. Chr., Revision nr. 52 as a variety of 

 Ü. opposita, at least I can not distinguish specifically from that species an authen- 

 tical specimen in Kew. It has the basal segments considerably enlarged and often 

 lobed, and it has 8 — 10 veins to a side, but as to other characters it agrees very 

 well with the typical form. 



64. D. riopardensis Ros.; C. Chr., Revision nr. 26 fig. 17. 



Area: South Brazil, Rio Grande do Sul. 



This is most probably a form of D. opposita var. rivulorum. 



65. D. coarctata (Kze.) C. Chr., Revision nr. 27 fig. 18. 



Area: Venezuela — Colombia. Cuba, Wright nr. 3925 (S, W), previously 

 determined as D. sagittata, which it resembles in general habit but totally diflerent 

 in pubescence. 



66. D. leucothrix C. Chr. Smiths. Misc. Coll. Ô3: 377. — Fig. 12 e. 

 Area: Bolivia. 



67. D. panamensis (Pr.) C. Chr., Revision nr. 28 fig. 19. Smiths. Misc. Coll. 53: 376. 



Area: Porto Rico, Jamaica, Cuba; Mexico to Panama, very common. 

 Additional synonyms of this variable species are, according to the original 

 specimens, the following: 



Lastrea Leiboldiana Pr. Epim. 41. 1849, Mexico, Leibolo (Hb. Presl!), exactly 



identical with P. litigiosum Liebm. 

 Aspidium Ghiesbreghtii Fourn. Mex. PI. 1: 94, 1872, Mexico, Ghiesbreght, 



BouRGEAU nr. 3615 (Mus. Paris!). 

 Nephrodium caribaeuin Jenm. Journ. Bot. 1886: 270; Bull. Dept. Jam. n. s. 3: 



21. 1896. 

 üryopteris caribaea C. Chr. Ind. 257. 1905. 

 Jamaica; Mt. Diabolo, Sherring (Kew, authentical specimen; New Yorli 



Bot. Gard., a leaf of Jenman's type collection received from Miss Slosson). 



Nearly identical with the narrow form of D. panamensis upon which Presl 



founded his new species. Jenman does not mention the glandular underside.
