Hab. Sweden to Siberia, Japan, Azores, Barbary, Himalayas, Bombay, Neilgherries, 

 Cochin, and Hong-Kong ; Mascaren Isles, Zambesi-land, Angola, Natal, Cape Colony ; 

 Canada and the Saskatchewan to Rio Janeiro. Of Presl's species we place here without 

 hesitation spectabilis, Willd., capensis and Hugeliana, Presl, Jfilsenbergii, H. & G., 

 gracilis, Link, obtusifolia, Willd., and Leschnaultiana, Wall. O.japonica, Thunb. (0. spe- 

 ciosa, Wall.), is a curious variety from Japan and the Himalayas, with the fertile and 

 barren fronds often quite distinct, the former being developed the earliest and soon dis- 

 appearing ; and it also occasionally happens that some of the lateral pinnae become 

 fertile, whilst the terminal ones remain barren. Mr. McKen sends a similar form from 

 Natal.

Sori on the back of the leafy part of the frond. A small genus, almost confined 

 to the South Temperate Zone, with the capsules of Osmunda, but the ordinary habit 

 of Polypodiacese. TAB. VIII. fig. 63.
