NIEREMBERGIA, Nat. Ord. Solanacece. 
The Nierembergias are veiy pretty plants with delicate, whitish flowers, tinted with lilac, and 
with a deep purplish lilac blotch in the center. The plant is slender and delicate, bearing abund- 
ance of flowers the whole summer. The Nierembergias are tender peren- 
nials, and are therefore suitable for house culture, or they may be treated 
^ as tender annuals, and will flower early in the season, if transferred from 
"ml ^^-ic^Mi %A frame or the green-house to the garden,

M^e cannot recommend the Nierembergia too 
highly. The engraving shows the flower of 
.natural size, and is a fair representation of its form, but the engraving representing the appear- 
ance of the plant does not give so good an idea of its character. 
NIGELLA, Nat. Ord. RanMuculacece. 
The Nigellas are curious, hardy annuals, with finely cut leaves, and very curious, showy 
flowers, which, from their singular construction, have acquired many odd names, as Love-in-a- 
Mist, Devil-in-a-Bush, etc. Seeds 
grow very readily, and may be sown 
in the open ground early in the spring, 
and in most sections in the autumn. 
They are natives of Asia Minor, Egypt^ 
and other Eastern countries, and the 
seeds, being aromatic, are extensively 
used both by oriental cooks and physi- 
cians. Indeed, they are supposed by 
Egyptian ladies to improve the complexion ; but as their ideas of a good complexion may not 
agree with Western notions, perhaps it would not be well to try the experiment. Both seeds and 
leaves, we believe, are used in India to prevent the ravages of moth and other insects among 
clothing, 
NO LAN A, Nat. Ord. Nolanacca:. 
Nolanas are trailing, hardy annuals, the plant fleshy and succulent, and with flowers veiy 
much resembling Convolvulus minor, but with more substance. The Nolana prefers a light soil, 
and it is seldom too hot or dry to suit its wants. The Nolana is a 
native of Peru and Chili. Seed may be sown in the border where 
the flowers are desired, or in a seed-bed in the garden, to be trans- 
planted as needed. Excellent for rock- work, baskets, etc. The 
Nolana delights in the same treat- 
ment, soil, &c., as the Portulaca, and 
may be used with the best effect in 
situations where our old Portulaca 
would be desirable. This class of 
plants, the natives of Southern climes, 
that delight in heat and drouth, are our choicest treasures in midsummer, Mdien the thermometer 
is above ninety much of the day, without a drop of rain for weeks.
