62. D. physematioides (Kuhn et Christ) C. Chr., Revision nr. 31. 
Area: San Domingo. 
63. D. opposita (Vahl) Urban; C. Chr. Revision nr. 25 fig. 15, 16; Smiths. Misc. 
Coll. 52: 375. 
Area. Type: Lesser Antilles, common. Different forms occur in Jamaica, 
Cuba, Florida, Mexico, Colombia— Peru. var. rivulorum (Raddi): Southern Brazil. 
I now regard D. amphioxypteris (Sod.) C. Chr., Revision nr. 52 as a variety of 
D. opposita, at least I can not distinguish specifically from that species an authen- 
lical 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, WnmnrcnT nr. 3925 (S, W), previously 
determined as D. sagittata, which it resembles in general habit but totally different 
in pubescence. 
66. D. leucothrix C. Chr. Smiths. Misc. Coll. 52: 377. — Fig. 12e. 
Area: Bolivia. 
67. D. panamensis (Pr.) C. Chr., Revision nr. 28 fig. 19. Smiths. Misc. Coll. 52: 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, LErBorp (Hb. Presv!), exactly 
identical with P. litigiosum Liebm. 
Aspidium Ghiesbreghtii Fourn. Mex. Pl. 1: 94, 1872, Mexico, GHIESBREGHT, 
BouncEau nr. 3615 (Mus. Paris!) 
Nephrodium caribaeum Jenm. Journ. Bot. 1886: 270; Bull. Dept. Jam. n. s. 3: 
21. 1896. 
Dryopteris caribaea C. Chr. Ind. 257. 1905. 
Jamaica; Mt. Diabolo, SHERRING (Kew, authentical specimen; New York 
Bot. Gard., a leaf of JENMAN's type collection received from Miss SrossoN). 
Nearly identical with the narrow form of D. panamensis upon which PREsL 
founded his new species. JENMAN does not mention the glandular underside.
