CHAPTER XXIII. 



THE GENERA ISOCHILUS, ARUNDINA, ARPO- 

 PHYLLUM, lONOPSIS, PACHYPHYLLUM, SCA- 

 PHYGLOTTIS, TETRAPELTIS, GEODORUM, 

 AND PONERA. 



These genera are inhabitants of various parts 

 of Asia and South America. Their cultivation 

 is but simple, and easily to be followed. 



The mode I pursue is in pots half filled with 

 potsherds, afterwards placing a thin layer of the 

 fibrous part of peat when the mould is beaten 

 out of it, and then potting the plant in a mixture 

 of well-chopped sphagnum, turfy peat, a little 

 sand, and a few small potsherds ; the plants, when 

 completed, should have their base nearly two 

 inches above the rim of the pot, with the mould 

 sloping a little towards the pot, they do not re- 

 quire large ones or removing very often, as they 

 do not produce their roots so freely as many of 

 this tribe: when the plants get too large for the 

 pots they are in, I shift them again into larger 

 ones; the time I prefer for this operation is from 

 the latter end of April to the beginning of June.
