Naturalisation in Extra-Tropical Countries. 331 



total quantity of tobacco raised in the United States during 1885 

 was 562,736,000 Ibs. from 752,520 acres, valued at 9,013,666 [J. 

 R. Dodge]. In India 641,000 acres were planted with tobacco. In 

 Hungary during the same year 140,516 acres were devoted to tobacco- 

 culture, the produce being 1,225,400 cwts. The Victorian import 

 during 1887 was 2,488,410 Ibs., valued at 252,426 (raw and manu- 

 factured). 



Niemeyera prunifera, F. v. Mueller. (Lucuma prunifera, Bentham. ) 



The Australian Cainito. An evergreen tree, sparingly dispersed 

 from the north of New South Wales through the coast-forests of 

 Queensland. The fruit is of a plum-like appearance and edible. 

 Culture is likely to improve its quality. 



Nuphar multisepalum, Engelmann. 



Western North-America. This Water-Lily produces nutritious 

 seeds, which taste like Broom-Corn, and are used locally for food, 

 but are more particularly valuable for waterfowl. Various species of 

 Nymphasa might be utilised in the same manner, irrespective of their 

 value as decorative lake- or pond-plants. The author naturalised the 

 British Water-Lily, Nymphasa alba (Camerarius), in Victoria long 

 ago. The very decorative N. gigantea (Hooker) extends naturally 

 in Eastern Australia to 30 S. 



Nyctanthes arbor tristis, Linne. 



India, up to Assam. This arborescent shrub or small tree (to 30 

 feet) may be grown in almost any moist regions, free from frost, for 

 the exquisite fragrance of its flowers, from which essence of jasmin 

 can be obtained. 



Nyssa aquatica, Linne. 



The Tupelo or Pepperidge. Eastern North-America. This large 

 tree can be grown in pools and deep swamps, and is thus well adapted 

 for aquatic scenery, though the foliage is deciduous. The spongy 

 roots serve as a substitute for cork and the floats of nets. 



Nyssa Silvatica, Marshall. (N. multiflora, Wangenheim.) 



Eastern States of North- America, where it is called the Forest- 

 Tupelo or Black Gum-tree [Dr. Asa Gray]; also called Sour Gum- 

 tree. Attains a height of about 50 feet. Suited for forest-soil ; 

 has horizontal branches and a " light, flat spray, like the Beech." 

 Can be propagated from cuttings. The wood is very hard, but light, 

 and almost unwedgable ; it serves for hubs of wheels, pumps, side- 

 boards of carts, trays, bowls, dippers, mortars, wooden shoes, 

 hatters' blocks and various turners' work. The foliage turns bright 

 crimson in autumn. The fruits are pleasantly acidulous, like those of 

 N. capitata (Walter) and of some other species, and often used for 

 preserves.
