424 MR. ©. CHRISTENSEN ON THE FERNS OF THE 
GLEICH ENIACE/E. 
73. GLEICHENIA LINEARIS (Burm.), C. B. Clarke; C. Chr. Ind. 322.—G. dichotoma, 
Baker, Fl. Maur. 460. 
Mahé, Silhouette, and Long Island, Gardiner! 
Common through the tropical and subtropical regions of the Old World, and closely 
related forms occur in tropical America. 
SCHIZHACEA. 
74. SCHIZÆA DIGITATA (Linn.), Sw.; C. Chr. Ind. 616.—5. digitata, var. intermedia 
(Mett.), Baker, Fl. Maur. 516. 
Mahé, Gardiner! 
This is the genuine S. digitata, a species widely distributed through tropical Asia and 
Polynesia, but, so far as Africa is concerned, known from the Seychelles only. The 
locality Madagascar is doubtful. Baker referred the Seychelles specimens to S. inter- 
media, a species from New Caledonia distinctly different from S. digitata by having the 
sporangia intermixed with long paraphyses. 
MARATTIACE. 
75. MARATTIA FRAXINEA, Sm. ; C. Chr. Ind. 414. 
Mahé, Gardiner! New to the group. 
Distributed through the tropics of the Old World. 
76. ANGIOPTERIS EVECTA (Forst.), Hoffm.; Baker, Fl. Maur. 517. 
Mahé and Silhouette, Gardiner! 
Widely spread through the Old World tropics. 
OPHIOGLOSSACEA. 
77. OPHIOGLOSSUM PENDULUM, Linn.; Baker, Fl. Maur. 517; C. Chr. Ind. 471. 
Mahé, Gardiner! Thomasset! Silhouette, Gardiner! Apparently common. 
Tropical Asia, Australia, and Polynesia, the South-east African islands, but not known 
from the African continent. 
78. OPHIOGLOSSUM PALMATUM, Linn. ; Kuhn, Fil. Afr. 17 8; C. Chr. Ind. 471. 
Seychelles, Pervillé (fide Kuhn, not seen). 
Florida and tropical America; Madagascar, Réunion, and Seychelles.
