840 FOREST CULTURE AND 
like seeds. The plant in congenial spots displaces 
nearly all other water-vegetation by the vigor of its 
growth. 
Nelumbo nucifera, Gaertner.* (Nelumbium, speci- 
osum, Willd.)—The Pythagorean Bean. Egypt; at 
Caspian and Aral Seas (46 degrees N.); Persia ; 
through India, where in Cashmere it occurs at an 
elevation of 5,000 feet; China; Japan; Amur (46 
degrees N.); tropical Australia as far south as 23 
degrees. The occurrence of this grand plant at the 
Ima, at Pekin, and at Astrachan proves sufficiently 
that we can naturalize it in Victoria. The Nelumbo 
requires deep water with a muddy bottom. The 
large white or rosy flowers are very fragrant. The 
seeds retain their vitality for several years. Accord- 
ing to the ancient Egyptian method, they are placed 
in balls of muddy clay and chaff, and then sunk into 
the water. 
Nephelium Litchi, Cambess. —South China, Co- 
chin-China and Philippine Islands. An evergreen 
tree, producing the Litchi-fruit. The pulpy arillus 
is of extremely pleasant taste, though not large. 
Nephelium Longanum, Cambess.—India and South- 
ern China. The Longan-fruit is obtained from this 
tree. It is smaller than that of the Litchi-tree. 
Nicotiana multivalvis, Lindley.—The Native Tobac- 
co of the Columbia River. Anannual. This with the 
following species can be utilized for certain kinds of 
tobacco. 
Nicotiana Persica, Lindley—The Shiraz Tobacco. 
Persia. Annual. This can be brought to perfection 
only in cool mountain regions. The mode of culture 
is somewhat different to that of the ordinary tobacco.
