ASPLENIUM. 



Description. A very extensive and widely dis- 

 tributed genus of hardy and exotic Ferns (prd. 

 Filices), exhibiting a wonderful amount of varia- 

 tion in height, habit, and cutting of the fronds. 

 Many of them are amongst the most valuable occu- 

 pant < of our cool and warm Fern houses, and the 

 genus is the heaviest contributor to the hardy 

 fernery, one species alone, Filix-fnemina, numbering 

 its varieties by the hundred. 



Propagation. By spores, in all cases ; and by 

 " bulbils " in a few instances, as, for example, 

 bnlbiferum and its varieties, and viviparum. 



Soil. The hardy species and varieties do well in 

 any light soil abounding in humus. For those 

 requiring stove and greenhouse temperatures, 

 equal parts of loam and peat, or loam and leaf soil, 

 with sand, answer well. A few pieces of charcoal 

 are beneficial. In the case of longissimum, which 



makes an elegant basket Fern, a little live Sphag- 

 num may be usefully introduced. 



Other Cultural Points. The hardy forms are 

 mostly deciduor.s, and thus need little water 

 during the winter, although a mulching of leaf soil 



/ 



ASPLEXIUM LUNULATl- M. (See p. 87.) 



serves the double purpose of keeping the roots 

 fresh and moist, and of protecting them from 

 frost. The stove and greenhouse species and 

 varieties need plenty of water at all times, and 

 Nidus and its varieties are by no means averse from 

 the use of the syringe. Liquid cow manure is a 

 capital stimulant through the summer months, and 

 it may be varied occasionally with a little clear 

 soot water. The chief insect pests are thrips, and 

 Snowy Fly (Aleyrodes), and they are especially 

 troublesome to the forms with broad, leathery 

 pinna?, such as obtusatum lucidum. Fumigation 

 will do no harm if it is not very strong, and this, 

 with the occasional use of the sponge, should 

 serve to keep insect pests under. Temperature for 

 the greenhouse forms, winter minimum. 40" ; stove, 

 58 to GO".
