08 FEEXS. 



corcovadenso, B. Innceolahmv, and B. longifolium gracile. The 

 first two thrive best in the cool end of the stove, while the 

 last should be grown in the greenhouse. They should be 

 grown in a mixture of peat, loam, and sandstone. 



DAVALLIA. 



All the species and varieties of this useful genus form 

 teautiful specimens, and are of great service to the exhibitor. 

 Among the finest for that purpose are D. canariensig, D. 

 elpf/ans, D. Fijv'iisu plumosa, D. Inrta cristata, D. Moorerina, 

 and D. pyxidata. The stove kinds require a strong moist 

 heat and a plentiful supply of water at the roots, and should 

 be grown in baskets or well-drained pans, using a compost of 

 fibious peat and sharp sand, with a large proportion of char- 

 coal and sandstone, to allow the water to pass freelv away. 

 The greenhouse kinds should be grown among firmer material, 

 with less charcoal in it, and receive less water at the roots. 



GLEICHEXIA. 



This is a specially attractive race of ferns, and indispens- 

 able to the exhibitor. Among the best for exhibition are 

 O. eircinata glauca, G. dicarpa lo7ujipinnata, G. dicliotoma, 

 G.flahellata, G. Mendelii, and G. rupestris. They all require 

 greenhouse treatment, and should be grown in well-drained 

 pans or shallow tubs, using a compost of fibry peat and silver 

 sand with a little charcoal. They grow naturally on the banks 

 of streams where the water overflows their roots at times, 

 thus indicating that they require a plentiful supply of mois- 

 ture. They require to be firmly potted, leaving a hai'd even 

 surface for the wiry creeping stems to run upon. This genus 

 of beautiful ferns have rather delicate and easily injured roots, 

 and liquid manure or manure in any form should not be given 

 to them. They can be increased by division or by layering the 

 stems in small pots.
