ADIANTUM. (MAIDENHAIR.) 



Description. Stove, greenhouse, and half-hardy 

 Ferns (ord. Filices) of considerable beauty and 

 value. Only one, pedatum, a native of North 

 America, is really hardy. Upwards of a hundred 

 species and varieties have been certificated by the 

 Koyal Horticultural Society since 185'J. 



Propagation. By spores, sown in heat and kept 

 close until germination has taken place ; and by 

 division of the old plants. 



Soil. Two parts of loam, one part of good leaf 

 soil, and sand, for the older plants ; equal parts of 

 loam and leaf soil, with rather more sand, for the 

 sporelings. 



Other Cultural Points. Although Adiantums are 

 really evergreen Ferns, and therefore must not be 

 allowed to get very dry, they all rest to some ex- 

 tent during the winter, and thus need considerably

less water then than they do during the growing 

 period. The popular cuneatum and its varieties 

 are commonly treated as deciduous Ferns, all the 

 fronds being cut down in the autumn, and they 

 answer very well to the treatment. 



The Beautiful farleyense. This rarely, if 

 ever, produces spores, and is propagated solely by 

 division. It delights in a strong heat, with plenty
