intermedium Colla [translucens (Kze) Fee]. JOHOW united P. irilobimi Cav. 

 and califoyjiicuDi Kaulf. with traiislucens, and they seem to belong to the same 

 small group, to which also P. Espiiiosae W'eatherby (Chile, Atacama) must be 

 rcferretl. 



c. PolvpodiioJi s. str., about 75 sp., mainly N. hemisph. and neotrop. 

 Masafiierae Phil. S. Peru to N. Chile (Antofagasta), Argent.; comp. i^g. 14 



and 16S. 33. \>ry close to P. pycnocarpiiui C. Chr. (Mex.-N. Chile). 



d. Xiplwptcris Kaulf. About 50, pantrop. 



tyichonianoides Sw. Trop. Amer. A puzzling record (see 2^g. 766). 



e. Plcopeliis Humb. et Bonpl. About 40, pantrop.; the following sp. wide- 

 spread. 



la}iceolatii>n L. Mex. and \\\ Ind. to subtrop. S. Amer. (also in Chile), St. 

 Helena, Tristan da C, Afr., Madag., Indomal., Hawaii. 



lUapJioglossiiui Schott. A pantrop. genus of more than 400 sp., very numerous 

 in And. S. Amer., 4 sp. on Tristan da C, and many sp. in Polyn. and Hawaii. 



Li)idenii (Bory) Moore. Mex. to Ecuad. and Braz. 



Gleicheniaceae. 

 GleicJienia Sm. About 130 sp., the majority of them referred to 5//f//<f?7/i- (Kaulf.) 

 Ching, to which also the species in J. P'ern. belong; about a dozen sp. spread 

 over the austral zone; 5 Chile, one extending to Falkl.; i S. Afr., i Madag., 

 Mascaren. and Seych. Is., i Tasm., i Tasm. and N. Zeal., 2 N. Zeal. 



quadripartita (Poir.) Moore. S. Chile to Fueg. 



pedalis (Kaulf.) Spreng. S. Chile, south to Chonos Is. 



cf. litoralis (Phil.) C. Chr. Hardly identical with this little known species and 

 perhaps only a form of G. pedalis. 



Ophioglossaceae. 

 OpJiioglossuDi L. 28 sp. recognized by Clausen {64); the genus "scattered with 

 remarkable uniformity over the habitable globe" (COPELAM) 6g. 12). 



fertiandezianum C. Chr. Not very near 0. ypaiicnse Mart. (Colomb., Braz.) 

 as Chris ri-:NSEX thought, but close to 0. scariosuni Clausen from Peru, Dept. Junin. 



Lycopodiaceae. 

 Lycopodiuin L. A large world-wide genus, badly ill-treated by Nessel, who listed 

 several undistinguishable species in J. P^ern.; see 2/i.g. ^66. 



j/Kii^r/Iimiiinn Sw. .S. Chile to P\ieg., P'alkl., S. Georgia, Marion I., Kerguel. 



scariosiiiH I^'orst. Chile, Valdiv. -Guaytecas Is. [L. gayajiuni Remy), N. Zeal.; 

 Tr(){). Andes, Braz. [L. Jiissicui Desv.). See I.e. J^S'] . 



In his treatment of the geographical groups distinguished by him, JOIIOW 

 included the ferns — no 1^'ern Allies were at that time known from Juan Fernandez. 

 All were classified as American exce[)t 3, Dicksonia berteroafia, said to be similar 

 to a species from T'iji, Ptrris bcrtcroaiia (identified with comans), and '' Aspleniimi 

 /oJigissiuiNiN Illume", the s[)ecies now known as BlecJinimi longicatida. In 1914 

 [22^) I went a step further; to my "Altpazifisches P^lement" 5 species were referred, 

 to the Trop. American 5, and all the rest to the Chilean. In 1934 I attempted 

 a more detailed subdivision (279, here translated from P>ench).
