HARDY TEENS. 



it in many places, yet we know no Fern that would give 

 greater pleasure to the Fern-fancier. 



STKUTHIOPTERIS. 



From the Greek strut Mos, an ostrich, and pteris, a Fern : 

 the fronds in form like that bird's plumes. A genus containing 



two noble hardy species. 

 The fertile fronds are con- 

 tracted, and not produced 

 until after the barren ones, 

 among which they are quite 

 hidden. One species is Ame- 

 rican, the other European, 

 but both perfectly hardy. 

 STEUTHIOPTEEIS GEE- 

 (G-ernian). This 



MANIC A 



plant makes a glorious tuft 

 of fronds, 3 or 4 feet high. 

 It does not materially differ 

 from the other species, but 

 the two are quite unlike any 

 other Fern, and at least one 

 of them should find a plaoo 

 in every hardy fernery both 

 where there is plenty of 

 room. 



S. PENSYLVANICA (Pen- 



sylvania), Fig. 79. Native 

 of North America. Deci- 

 duous. Sterile fronds about 

 3 feet high, pinnate ; pinnae acuminate, deeply-divided, with 

 segments rounded. Fertile fronds about 1 foot high, con- 

 tracted, pinnate. This makes a noble specimen, and may 

 be propagated like the other by division.
