Cult. The species of Jmmdnma being all annuals, and tor 

 the most part natives within the tropics, the seeds of them must 

 be sown in pots, which should be placed in a hot-bed fr^"™^J^^ 

 in a stove, and when the plants have grown to the height oi 

 inches, they may be transplanted into other pots, 3 or 4 plants 

 in each ; these pots should be placed in the stove or warm part 

 of a green -house, placing each in a pan of water. Some ^^ "^^ 

 plants may also be planted out in the open ground, in a shel-
