SWISS FERNS. 



As we have remarked before, it may surprise some to hear 

 that there are very few ferns in Switzerland which we have 

 not in England, and those few are rarely met with. But 

 then, on the other hand, there is an abundance of many of 

 those which are scarce with us, and, like the flowers, they 

 grow with a freedom and a luxuriance which make them 

 seem almost another thing. 



We therefore merely give a short notice of the Swiss. 

 Ferns, following the arrangement of M. Morthier, leaving 

 fuller details to be gained from the many books on the 

 subject which are published in this country. 



Teems used. 

 Spore, seed. 



Sporangia, cases, oi* capsules, containing the seed. 

 Soi'i, the arrangement of these capsules in little clusters on the back 



of the leaf, or on spikes or panicles separate from it. 

 Jndusium, a thin membrane which sometimes covers the sori when young 

 Pinna, the primary division on each side the main stalk. 

 Segment, the division of the pinna. 

 Frond, the leaf.
