MUCUNA MUSHROOM. 275 



Mucuna (Cow-itch). Leguminos&. 



Propagation may be effected by seeds, or by cuttings 

 of half-ripened wood under glass. 



Muehlenbeckia, Sarcogonum. Polygonacece . 



Seeds. Increased usually by cuttings, taken in early 

 summer, in a frame. 



Mulberry (Morusalba, M. nigra, M. rubra^ etc.). Urticacecs. 



New sorts are grown by seeds, which should be han- 

 dled in the same manner as small-fruit seeds. Named 

 varieties are multiplied by cuttings of the root, or of ma- 

 ture wood, and sometimes by layers. They may be cion- 

 budded in the spring (see Fig. 115). In the south, cuttings 

 of the Downing mulberry are used for stocks (Fig. 105). 



The common white mulberry was formerly used as a 

 stock for named varieties, but Russian mulberry seedlings 

 are now much used. The stocks may be top-worked out- 

 doors (as explained above) or root-grafted in the house. 

 The fancy varieties are commonly crown-worked, in the 

 house in winter, the stocks being grown in pots or boxes 

 for the purpose. They are then kept under glass until the 

 weather permits them outdoors. By this method choice 

 specimen trees are procured, but they are readily handled 

 by cheaper methods. The weeping and other ornamental 

 sorts are worked upon the Russian mulberry. 



Mulberry, Paper. See Broussonetia. 



Mullein. See Verbascum. 



Musa ( Banana, or Plantain-tree ) . Scitaminea. 



Seeds may be sown in heat during spring. Suckers 

 are used for those species which produce them. Many 

 of the species do not produce seeds freely, and suckers 

 must be relied upon. Musa Ensete is propagated by 

 seeds. See Banana. 



Muscari, including Botryanthus (Grape Hyacinth). Liliacecz. 

 Increased by seeds ; also by bulbels, which are obtained 

 by lifting the old bulbs early in the autumn, about every 

 second year. 

 Mushroom (Agaricus campestris). 



Break up the commercial spawn into pieces about as 



large as a hen's egg, and plant it two or three inches deep 



in drills or holes, using from one-half-pound to a pound of 



spawn to each square yard of bed. 



The spawn is the mycelium of the fungus grown in a
