DERIVATION OF THE FLORA AND FAUNA 22$ 



chilense (Kaulf.) Mett. Centr. Chile to W. Patag.; Falkl. Belongs to the capense 

 group (S. Afr., Indomal.), see 62. 2^] and i6g.^']. 



cycadifolium (Colla) Sturm. Almost too near B. viagellmiicum (Desv.) Mett. 

 (S. Chile to Fueg. and Falkl.); both related to B. tabulare (Thunb.) Kuhn (S. and 

 E. Afr., Madag., Mascaren.). 



longicauda C. Chr. Very near B. Sprucei C. Chr. from trop. S. Amer. (Ecuad., 

 Boliv., Braz.), see 2^0. HiCKEN records it from Tucuman in Argent. (133. 246), 

 a statement overlooked also by Christensen. 



Pellaea Link. About 80, the majority in S. Amer. (south to Chile), S. Afr. and 

 islands; N. Amer. north to Canada; N. Zeal. 



chilensis Fee. Very close to P. nivea (Poir.) Prantl (Ariz.-Chile), see 62. 30. 

 Hypolepis Bernh. A pantrop. genus of 45-50 sp., half of them trop. Amer., several 

 Afr. and surrounding islands, others N. Guin.-E. As. and Austral. -Poly n. 



rugosida (Labill.) J. Sm. Centr. and S. Chile; the typ. sp. Austral., N. Zeal., 

 var. villosoviscida (Thouars) C. Chr. [61. 6) on Tristan da C; Polypodiu7n viscidum 

 Roxb. from St. Helena very likely is another variety. 

 Adiafitum L. 200-225; widely distributed but most numerous in S. Amer. 



chilense Kaulf. Peru-Chile, Patag., Falkl. 

 Pteris L. 270-280, mainly trop. but extending north to S. Eur. and south to S. Afr., 

 Tasm. and N. Zeal. 



chilensis Desv. Near P. leptophylla Sw. (S. Braz.). 



semiadnata Phil. S. Chile, Valdiv.-Huafo I. A distinct sp., possibly related 

 to P. pidchra Schlechtd. from Mexico. 



berteroana Ag. Related to P. comans Forst. (Austral., Tasm., N. Zeal.) and 

 particularly to P. endlicheriana Ag. (Norfolk I.). 



Hisiiopteris (Ag.) J. Sm. An assemblage of trop. and austr.-circump. forms which 

 according to CllRlSTENSEN cannot claim to be regarded as different species 

 [62. 36), whereas Copeland [6g. 60) speaks of local, derived species (a concentra- 

 tion in Indomal.-Polyn.) differing sufficiently from the following polymorphous taxon. 



incisa (Thunb.) J. Sm. Chile, S. Afr., Tristan da C, Austral, Tasm., N. Zeal., 

 Polynes. 



Polypodiwn L. coll. World-wide; Ind. Fil. registers more than iioo sp. The genus 

 is now generally broken up, most radically by CoPELAND, who segregates numer- 

 ous genera partly restored from synonymy. 



a. Granimitis Sw. About 150; an essentially southern genus, reaching north 

 to West Indies and Bonin Is. and richest developed in New Guinea. 



magellanica Desv. S. Chile, Valdiv.-Fueg,, And. Patag. (Rio Negro); Tristan 

 da C, Marion I. In 62. 36 as P. Billardieri (Willd.) C. Chr. var. niagellanician 

 (Desv.) C. Chr., but later restored to specific rank by CHRISTENSEN 61. 18. Distri- 

 bution of Billardieri: Austral., Tasm., N. Zeal., Auckl. and Campb. Is., Lord 

 Howe and Norfolk Is., St. Paul and N. Amsterd. Is., Kerguel. 



b. Synammia Presl, According to Copeland 6g. 184 only one species, wS. 

 Feuillei (Bert.) Copel. [Polypodiwn trilobmn Cav.), but I fail to see how we could 

 exclude the island species.
