In addition 
to the above, Dr. F. 
W. Stansfield reports 
appearance of 
presumed 
prothalli on 
cut and layered edges of 
Polypodium vulgare grandiceps Parker, culture then failing, and 
plants in writer’s hands of Scol. v. crispum fimbriatum Stansfield 
(Stansfieldii) are reported by Mr. H. Bolton, of Warton, near 
Carnforth, to have resulted from layered edges of same 
variety. It seems probable that any varieties tending to 
produce filamentous tips or extremely fine divisions might 
become aposporous under close culture.
