DERIVATION" OF THE FLORA AND FAUNA 223 



chjlense (Kaulf.) Mett. Centr. Chile to W. Patag.; Falkl. Helongs to the capense 

 group (S. Afr., Indomal.), see 62. 2"] and /^p. 47. 



cycadifolium (Colla) Sturm. Ahnost too near /). i)ia^cllanicu))i (Desv.) Mett. 

 (S. Chile to Fueg. and Falkl.); both related to />. iabularc (Thunb.) Kuhn (S. and 

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



longUauda C. Chr. Very near />'. Sprucci C. Clir. from trop. S. Amer. (Ecuad., 

 Boliv., Hraz.), see 2^0. HiCKF.x records it from Tucuman in Argent. (7??. 246), 

 a statement overlooked also by CllRlSTENSEX. 



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

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



chilensis Fee. \'er\- close to /-*. iiivea (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 X. Guin.-E. As. and Austral.-Polyn. 



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

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

 Roxb. from St. Helena ver}' likely is another variety. 

 Adia)itum L. 200-225; widely distributed but most numerous in S. Amer. 



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

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

 Tasm. and X. Zeal. 



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



seniiadnata Phil. S. Chile, \'aldiv.-Huafo I. A distinct sp., possibly related 

 to P. ptdcJira Schlechtd. from Mexico. 



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

 particular!}' to P. endlicJicriiDia Ag. (Xorfolk L). 



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

 according to Christensex cannot claim to be regarded as different species 

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

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



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

 Polynes. 



Polypodium L. coll. World-wide; Ind. p-il. registers more than iioo sp. The genus 

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

 ous genera parth- restored from synonymy. 



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

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



magellanica Desv. S. Chile, Valdiv.-F'ueg.. And. Patag. (Rio Xegro); Tristan 

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

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

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

 Howe and Xorfolk Is., St. Paul and X. Amsterd. Is., Kerguel. 



b. Synammia Presl. According to CoPELAXD 6g. 184 only one species, 5. 

 Feuillei (Bert.) Copel. {Polypodium trilobuui Cav.\ but I fail to see how we could 

 exclude the island species.
