LIMNOCHAEIS. 179 



LiMNOOHARIS. 



L. Humboldti. — This very handsome plant should be 

 potted in good rough loam, and placed in a shallow part of 

 the aquarium. The leaves are ovate, smooth, and of a 

 bright light green colour, and float upon the surface of the 

 water. The flowers are large, bright yellow, and produced 

 very freely all summer. Native of Brazil. 



Nelumbium. 



This splendid species can be grown in tubs or cisterns, as 

 the leaves and flowers both rise several feet above the water ; 

 during the resting season they may be allowed to get tolerably 

 dry, though not quite so. Good rich loam and well-decom- 

 posed manure suits them, but they require strong heat to 

 induce them to flower. 



N. speciosum. — This is the sacred Bean of the Egyptians. 

 The leaves of this fine plant are about eighteen finches in 

 diameter, peltate, orbicular, light green in colour, and rising 

 upon slender stems, which grow about four feet high. The 

 flowers rise to the same height as the leaves and are very 

 large, of a delicate rose and white, and very fragrant. It is 

 a common plant in China, where it is held in high esti- 

 mation, and it is also widely distributed through the East 

 Indies. 



Nymph^a. 



A lovely genus of plants, which should be grown wherever 

 accommodation can be afi'orded them. They will grow and 

 bloom most profusely in strong heat, but will thrive almost 

 as well if treated more temperately. The best plan is to 

 plunge them into water at a temperature of about 80° or
