the front of the border, and are beautiful annuals for pots. 
N. atomaria,—Dotted Love-grove——The growth is the 
same as the preceeding, with flowers which are white, dot- 
ted with dark-purple. It is the original of several of the 
garden varieties, among which are: WV. discoidalis elegans, 
‘in which the flowers are of a light chocolate, or reddish- 
maroon color, conspicuously and distinctly bordered with 
white, and W. discoidalis vittata with nearly black flow- 
ers, broadly margined with white. 
N. maculéta.—Spotted Love-grove.—Similar in habit 
and size of flowers to WV. insignis, but the white flower 
has a dark-violet blotch on each one of the petals. WV. 
aurita, with purplish-blue flowers, is sometimes cultivated. 
NICOTIANA,—Tosacco. 
[Named for Jean Nicot, who first introduced the plant into France.] 
Nicotiana Tabécum,—Tobacco.—This is cultivated in 
fields for its narcotic leaves. The flower is somewhat 
showy, and it may be grown in the garden as a curiosity, 
as well as for its leaves, which are useful to destroy in- 
sects. Its decoction, the powder of the leaves, and the 
smoke produced when they are burned, are all used by the 
gardener in freeing his plants from insects. It would be 
well if the plant were raised only for the destruction of 
insects, rather than, as I fear is the cause, for the destruc- 
tion of human beings. 
N. longifléra.—Long-flowered Tobacco.—Star Petunia. 
—An annual species, with much the habit of a Petunia, 
with pure white flowers, having a long tube and a star- 
like limb to the corolla,
