MUCUNA MUSHROOM. 275 



Mucuna (Cow-itch). Leguminoscr. 



Propagation may Ije effected by .seed.'^, or Ijy cuttings 

 of lialf-ripened wood under glass. 



Muehlenbeckia, Sarcogonum. Polygonacccr. 



Seeds. Increased usually by cuttings, t.iken in early 

 summer, in a frame. 



Mulberry (J/c5;7(.S(z/i')(Z, M. nigra, J/, rubra, etc.). Urticacea:. 



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. Tiiey may be cion- 

 budded in tlie spring (see Fig. 1 15). In the south, cuttings 

 of the Downing mulberry are used for stocks (Fig. IU5). 



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 jiols or bo.xes 

 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 \'erbascum. 



Musa (Banana, or Plantain-tree). Sc-ilaiiiinccc. 



Seeds may be sown in heat during spring. Suckers 

 are used for those species which produce them. iMany 

 of the species do not produce seeds freely, and suckers 

 must be relied upon. ]]Iusa Ensetc is |iropagated by 

 seeds. See Banana. 

 Muscari, including Botryanthus (Grape Hyacinth). Liliacecc. 

 Increased by seeds ; also by bulbels, which are obtained 

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

 second year. 

 Mushroom {Agaricus campcstris). 



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
