forme and riliatum, the tiny bulbils as on the pinnules of 

 A. capillus veneris imbricatum, and the root bulbils as on 

 A. Moorei and others. 



In the Aspidiums the proliferations mostly occur in the 

 form of bulbils on the main rachis, and these, if the 

 fronds are pegged down, on suitable soil will soon root, 

 and good plants may be established before severing 

 them from the parent ; but it is difficult to get them 

 off without damaging the fronds. 



In the gymnogeammas we have an interesting example 

 inG. scluzophylla ghriosa. This invariably produces one 

 bulbil, or young plant, at the extremity of each frond, 

 and in some instances the side pinnae will also produce 

 bulbils, and if the fronds are pegged down, young 

 plants may soon be established. Small pots filled, with 

 suitable soil are best where there is only one bulbil 

 at, or near the extremity of the fronds. 



The Hemiomtis produce young plants on the short 

 fronds which lie on the surface. They root, and soon 

 form a cluster of young plants round the parent. 



In the chelanthes we have one example, viz. Bergiana 

 (or Hypolepis Bergiana). Many of the Nephrolepis produce 

 young plants from the spreading stolons, and others 

 form bulbils under the soil. In the Platyceriums the 

 proliferations occur on the roots, and of those in 

 ordinary cultivation, P. grande is the only species which 

 has failed to reproduce from the roots. 



In the ivoodivardias we have two distinct forms of 

 proliferation ; W. orientalis having numerous tiny bulbils 

 on the surface of the fronds. These stand up with one 

 small frondlet, and when touched fall off easily. Treated 

 in the same way as small seedlings, they soon make 

 roots. 



In W. radicans it is rarely that more than one bulbil 

 is produced on each frond, and this is on the rachis 

 towards the extremity. A round scaly bulb is first
