Asplenium Viride (The Green Spleenwort) 



(Plate VII) 



This Fern (Fig. 46) is very similar in make to Asp. trichomanes , 

 but has bright green stalks and midribs instead of black ones, and 

 the pinnse are not jointed at the junction with the midrib. It is 

 not usually found associated with Asp. trichomanes, but grows in 

 rock crevices, in moist mountain districts, often at high elevations, 

 even associating with the Holly Fern (Polysliclium lonchitis), but 

 is not, like that Fern, confined to high levels, since we have found it 

 in the rocks on the banks of streams of little elevation. It is not 

 easy to grow under cultivation, requiring cool air and moisture. 

 Soil should be mixed with much broken porous stone, and well 

 drained ; usual size, five to six inches. A few varieties have been 

 found, but none of value.
