HARDWICKE'S SCI EN C E-GOS SIP.

Lastrea marginalis. The last named has the cover 



(iudusium) of the spore-cases white.

Two other species of the same genus may be named 

 as worthy of attention,— Goldiu's Fern, {Lastrea 

 Goldiana) and Siebold's Fern {Lastrea podophylld). 

 The latter is from Japan, and probably would hardly 

 endure the winter's frosts unharmed. 



Our two rare little Woodsias have representatives 

 in the United States and Mexico, with fronds one 

 foot and upwards in length. The Mexican Woodsia 



Fern {Pohjstichum acrostichoides) as affording a 

 pleasing associate with our native Shield Ferns, 

 and equally capable of standing the climate. And 

 an evergreen species of Cyrtomium from Japan 

 {Cyrtomium falcatum), with rich dark fronds more 

 than eighteen inches in length, with large leaflets.

{Woodsia mollis) and Perrin's Woodsia {Woodsia 

 obtusa) are both hardy, and very desirable for an 

 open-air fernery. 

 Finally we might commend an American Shield 



Fig. 72. Cyrtomium falcatum. 



It is the more desirable as it serves to illustrate a 

 genus of which we have no indigenous species. 

 It is quite possible that some species has been 

 omitted which is equally hardy, 

 and equally worthy with the fore- 

 going for out-door culture ; but 

 we have named sufficient to prove 

 that an excellent collection of 

 exotic ferns may be grown out of 

 doors, many of which are pro- 

 bably unknown to amateurs. It 

 has been a necessity to employ 

 the botanical names, because with- 

 out them it would be very difficult 

 to order them from a nurseryman, 

 should any of our readers be so 

 disposed. The majority of the 

 above are too large to be grown in a closed 

 case. The woodcuts illustrate the fructification, 

 but hardly give any idea of the appearance of the 

 fronds.
