68. PoLYPODiUM SERRULATUM (Sw.), Mett. ; Baker, PI. Maur. 504 ; C. Chr. Incl. 563. 



Mah^, Thomasset ! 



Distribution according; to Hieronymus (' Hedwigia,' vol. xliv. 80) : — Tropical America 

 (common), tropical West Africa, Madagascar, Mascarenes, Seychelles. 



59. Polypodium albobrtjnneum, Baker, PI. Maur. 505 ; C. Chr. Ind. 508. — P. sechel- 



larum, part., Baker, PI. Maur. 505. 



Mah^, Home, 681 ! 682 ! Gardiner ! Thomasset ! Silhouette, near the summit, scarce ; 

 epiphyte high up on trees. 



Endemic. 



P. sechellarum. Baker, was founded partly on a small sterile plant from Mahe (Some, 

 n. 194) and partly on a single leaf from Maui'itius {Lady Barkly), both of which I have 

 seen. The description in PI. Maur. is evidently written from the Mauritian specimen, 

 which belongs to a species distinct from P. albohrunneimi. The specimen from Mahe is, 

 I have no doubt, only a small sterile plant of P. albohrunneimi ; some of the rather 

 numerous specimens collected by Gardiner agree exactly with it. P. sechellarum. Baker, 

 is thus not known from the Seychelles, and the name therefore is very inappropriate. 



60. PoLYPODiUM CULTRATUM, Willd., var. ELASTICUM (Bory). — P. elasticum, Bory. 



P. asplenifolitmi, var. minor, Mett. ; Kuhn, Fil. Afr. 146. P. cultratum. Baker, PI. 

 Maur. 505. 

 Mahe, on tree-trunks over 2000 feet, rather scarce, Gardiner ! Thomasset ! 

 P. cultratum (type) is a tropical American species, and is also found in the island of 

 Pernando Po, Guinea. The variety elasticum is apparently confined to the Mascarenes 

 and Seychelles. It is very like the type, especially some of its smaller forms, but it is 

 more hairy, with longer and shorter hairs mixed on the upper surface and along the 

 margins. 



61. PoLYPODiTJM PUNCTATUM (Linn.), Sw. ; C. Chr. Ind. 557. — P. irioides, Lam. ; Baker, 

 PI. Maur. 507. 



Mahe, Thomasset ! 



Through the tropical regions of the Old World. 



62. PoiiYPODirM PHYMATODES, Linn. ; Baker, PI. Maur. 508 ; C. Chr. Ind. 553. 

 Mahe, Gardiner I Thomasset ! Bird Island, in dry places. Fryer ! Long Island, 



Gardiner] Silhouette, Gardiner \ 



Distribution. Prom South Africa through tropical Africa, Asia, Australia, and 

 Polynesia to Corea. 



63. Cyclophorus spissus (Bory), Dcsv. ; C. Chr. Ind. 201. — Polypodium spissutu, Bory; 

 Kuhn, Pil. Afr. 153. P. adnascens, Baker, PI. Maur. 506.
