sterile frond are quite variable in cutting; more so 

 than one would realize without a careful comparison 

 of specimens though several forms are so distinct as 

 to be regarded as varieties if not species.

 I was, till the middle of July 1909, under the same 

 impression as most amateur botanists that the fern 

 was rare and local. On July nrst I found by accident 

 about a score of these ferns in the corner of an up- 

 land pasture. Investigation disclosed hundreds up and

 ten miles north of Port Hope. About July 20th I was 

 fern hunting with an old Oxford chum near Lanark, 

 Ontario and while examining a fine clump of inter- 

 rupted fern which was surrounded by sterile fronds of 

 the native fern, I once more, by accident spied a group
