Nclumbium — Nicotiana. 1 63 



sheltered from sudden changes of the atmosphere. A 

 mixture of good loam, sharp sand, and charcoal seems 

 to answer it best. Multiplied by division of the root- 

 stocks, or by seed. Wherever there is a contrivance for 

 heating the water in a small pond or tank in the open air, 

 these two remarkable plants would be well worth a trial. 



Nicotiana Tabacum {Common Tobacco). — There 

 are several varieties of this well-known plant, distinguished 

 by the different length and width of their oblong lance- 

 shaped leaves and the lighter or deeper colour of their 

 rosy flowers. A deep, well-drained, light soil, rich in 

 decayed vegetable matter, is essential to this plant, as is 

 also copious watering in summer. As it is so readily 

 raised from seed, and grows luxuriantly in rich soil, I need 

 not say it is a very desirable subject for association with 

 the Castor-oil plant and the like, and especially suited for 

 the many who desire plants of noble habit, but who can- 

 not preserve the tender ones through the winter under 

 glass. It should be raised in a hotbed, and put out in 

 May. Height, 6 ft. or more. N. macrophylla is the 

 finest variety. 



Nicotiana wigandioides. — A species of recent in- 

 troduction, with a simple stem 6 ft. or more high, and 

 very large, broad, woolly leaves which grow in a some- 

 what erect position. If placed in a hothouse at the close 

 of the year, it becomes woody and branching, and assumes 

 an arborescent habit. Requires good substantial, well- 

 manured soil, and copious watering. This is a useful 

 plant for grouping with the medium-sized tender subjects 

 in rich, light, well-drained soils, and should be planted 

 out about the middle of May.
