Nephelium Longanum, Cambess. 
India and Southern China. The Longan-fruit is obtained 
from this tree ; it is smaller than that of the Litchi-tree. 
Nicotiana multivalvis, Lindley. 
The Native Tobacco of the Columbia River. An annual. 
This with the following species can be utilized for certain 
kinds of Tobacco. 
Nicotiana Persica, Lindley. 
The Shiraz Tobacco. Persia. Annual. This can bo brought 
to perfection only in cool mountain regions. The mode of 
culture is somewhat different to that of the ordinary Tobacco. 
Moderate irrigation is favorable. The plants when ripe are 
cut off and stuck into the ground again until they become 
yellow. They are then heaped together for a few days in 
the drying-house. They are then packed into thin strata 
and placed into bags, for pressure and daily turning. 
Nicotiana quadrivalvis^ Pursh. 
The Native Tobacco of the Missouri. An annual. 
Nicotiana repanda, Willd. 
Cuba, Mexico, Texas. Annual. It is utilized for some of 
the Havannah Tobaccoes. 
Nicotiana rustica, L. 
Tropical America. Annual. Some sorts of Eastern India 
Tobacco, of Manilla Tobacco and of Turkey (for instance 
Latakia) Tobacco are derived from this particular species. 
Nicotiana Tabacnm, L.* 
The ordinary Tobacco-plant of Central America. Annual. 
Various districts with various soils produce very different 
sorts of Tobacco, particularly as far as flavor is concerned, 
and again various climatic conditions will affect vastly the 
Tobacco-plant in this respect. We can thus not hope to 
produce for instance Manilla or Havannah Tobacco in our 
latitudes, but we can anticipate to produce good sorts of 
our own, more or less peculiar, or we may aspire to pro- 
ducing in our rich and frostless forest valleys a Tobacco
