POLYPODIUM VULGARE, var. SEMILACERUM {Link)

 Syn. Hibernicum. 



By Mr. Wollaston. The forms of Polypodium vulgare seini- 

 lacernm may fairly be considered analogous to the decompositum 

 forms of Polystichum angulare, and in either case the character 

 can generally be developed, to a certain extent, from the normal 

 form by luxuriant growth. 



Some of the finest of the very numerous forms of semilacerum 

 have been found by Mr. Barnes, Mr. Wollaston, and Mr. Barnard 

 Hankey. 



"The name semilacerum was originally given by Professor Link 

 of Berlin, and was adopted by me for the British plant (i.e. the 

 Irish) believing it to be the same." — Note by Mr. Moore.
