24 ORCHID- grower's manual. 



This is effected by bending the old pseudobulbs round the 

 basket or pots in which they are growing, or by .cutting the old 

 flowering bulbs away from the plant, and laying them on some 

 damp moss in a shady and warm part of the house, with a 

 good supply of moisture. In either case, they will break and 

 make roots and new shoots, after which they may be potted 

 or put in baskets. Such kinds as D. Jenkinsii, D. arjgrer/atum, 

 D. formosum, 1). speciosum, D. densiflorum, and similar grow- 

 ing sorts, are increased by simply dividing the plants. 



The species of Aendes, Vanda, AngrfBCum, Saccolahlum, 

 CamarotiSf Fienanthera, and similar growing kinds, are all 

 propagated by cutting the tops off the plant just below the 

 first root, or by taking the young growths from the bottom of 

 the plant. After they have formed roots they should be cut 

 off with a sharp knife, and afterwards put on blocks or in 

 baskets with some sphagnum moss, and kept in a warm and 

 damp part of the house, without receiving much water till 

 they have begun to grow, when they may have the usual 

 supply. Odontoglossums, Oncidiums, Zygopetalinns, Sohralias, 

 TrichopiliaSj Stanliopeas, Schomhurgkias, Peristerias, Mor- 

 modes, Miltonias, Lycastes, Leptotes, Lalias, Galeandrafi, 

 Kpidendrums, Cgrtopodiums, Cyrtochilums, Cymbidmms, 

 Cycnoches, Coryanthcs, Ccelogynes, Cattleyas, Calanthes, 

 Brassias, Bletias, and Barkerias, are all propagated by 

 dividing them into pieces, each having a portion of roots 

 attached to it, and a young bulb or growing point. 



Thunia alba and T. Benso7ii(B are very easily increased. 

 The best way is to cut the old pseudobulbs off after the young 

 ones have begun to flower, that is, just before the plant has 

 made its growth. The pseudobulbs should be cut into pieces 

 about six inches long, and then put into a pot in some silver 

 sand, with a bell-glass over them, till they have struck root ; 

 they should then be potted in some fibrous peat and moss,
