PROPAGATION AND IMPREGNATION. 95 



being careful not to injure the roots ; each piece should 

 have some roots attached to it. After they are cut 

 through they should be parted, potted, and put into some 

 shady part of the house, and not receive much water at 

 the roots until they have begun to grow and make new 

 roots, when they may be liberally watered. Dendrobium 

 nobile, Pierardii, pulchellum, macrophyllum, Devonianum, 

 and varieties of similar growth are easily propagated. 

 This is done by bending the old pseudo-bulbs round the 

 basket or pot 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 part of the house with a 

 good supply of moisture. After they break and make 

 roots they may be placed in pots or baskets. Such sorts 

 as Dendrobium Jenkinsii, aggregation, formo sum, specie sum, 

 and densiflorum and varieties of similar growth are in- 

 creased by dividing the plants. 



Aerides, Vandas, Angrcecums, Saccolabiums, Camarotis, 

 Renantheras, and plants of similar growth are propagated 

 by cutting off the tops of the plant just below the first 

 root or by removing the shoots which spring from the 

 root or form in the axils of the leaves. 



The young plants should be put on blocks or in baskets 

 with some sphagnum moss, and kept in a warm damp 

 place till they begin to grow, receiving little water at 

 first. 



Odontoglossums, Oncidiums, Zygopetalums, Sobralias, 

 Trichopilias, Stanhopeas, Schomburgkias, Mormodes, Ly- 

 castet, Peristerias, Miltonias, Lcelias, Leptotes, Epidendrums, 

 Galeandras, Cyrtochilums, Cymbidiums, JBrassias, Cyrto- 

 podiums, Cattleyas, Bletias, Cycnoches, Coryanthes, Coelo- 

 gynes, Barkerias, Calanthes, Aspasias, are all propagated
