GROBIA, ETC. 61 



growing kinds. The wood for use should first 

 be covered over with sphagnum, and fastened 

 with lead-wire ; then placing the plant upon it, 

 and adding more over its roots, fastening it down 

 in the same way ; a plentiful supply of water 

 during its growth will be necessary ; but during 

 the season of rest very little is required. 



The genus Paxtonia does not require to be 

 elevated at all, if there be a good drainage in 

 the pot ; the same compost will also do for it, 

 excepting the leaf-mould, which should be rotten 

 wood, or small potsherds. 



They may likewise be grown on chumps of 

 wood covered with sphagnum ; but they then 

 will require a greater supply of water during the 

 time they are growing, which is generally be- 

 tween the latter end of April and the beginning 

 of June, when potting or blocking should be 

 done, as they are then forming their fresh roots 

 from the young shoots which at that time are 

 forming ; and when they have completed their 

 season's growth a slight watering will only be 

 required about once a week. Like all other 

 Orchidese they require a low temperature 

 during the resting season, but while growing, a 

 temperature such as is recommended for the 

 Indian species. 



The genus Grobya and Ccelia will succeed 

 better in the South American house.
