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

 and californicum Kaulf. with translucens, and they seem to belong to the same 

 small group, to which also P. Espmosae Weatherby (Chile, Atacama) must be 

 referred. 



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

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



and Ji^c?. 33. Very close to P. pycnocarpjun C. Chr. (Mex.-N. Chile). 



d. Xiphopteris Kaulf. About 50, pantrop. 



trichouianoides Sw. Trop. Amer. A puzzling record (see z^g. 766). 



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

 spread. 



lanceolatum L. Mex. and W. Ind. to subtrop. S. Amer. (also in Chile), St. 

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



Elaphoglossujn 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. 



Lhidenii (Bory) Moore. Mex. to Ecuad. and Braz. 



Gleicheniaceae. 

 Gleichenia Sm. About 130 sp., the majority of them referred to kS7/c//^;7<'j- (Kaulf.) 

 Ching, to which also the species in J. Fern, 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. 

 Ophioglossiim L. 28 sp. recognized by Clau.SEN [64); the genus "scattered with 

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



jernandezianum C. Chr. Xot very near 0. ypanense Mart. (Colomb., Braz.) 

 as CllRlSTENSEN thought, but close to 0. scariosnni Clausen from Peru, Dept. Juni'n. 



Lycopodiaceae. 

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

 several undistinguishable species in J. P^ern.; see z^g. 766. 



magellanicum Sw. S. Chile to P^ueg., P"alkl., S. Georgia, Marion I., Kerguel. 



scariosmn Forst. Chile, Valdiv. -Guaytecas Is. [L. gayanuvi Remy), N. Zeal.; 

 Trop. Andes, Braz. (Z. Jussieui Desv.). See I.e. "J^^ . 



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

 included the ferns — no Fern Allies were at that time known from Juan P'ernandez. 

 All were classified as American except 3, Dicksonia herteroajia, said to be similar 

 to a species from Fiji, Pteris berteroana (identified with comajis), and ''Asplejuiim 

 longissimian Blume", the species now known as Blechnuni longicauda. In 1914 

 (227) I went a step further; to my "Altpazifisches Element" 5 species were referred, 

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

 a more detailed subdivision (^jp, here translated from P^rench).
