Brazil. 
N. Scheremetieurit. This is a larger 
‘grower than some of the genus, attaining 
a diameter of 18 inches or 20 inches ; 
inner leaves bright red; flowers purple 
and white. Brazil. 
N. spectabile. Has stout recurved leaves, 
reddish purple at the tips with greyish 
white bands on the under side. Flowers 
violet, produced in a dense mass. <A 
native of Brazil. 
Insects.—The texture of the leaves of 
Nidulariums is so hard, that they do not 
afford food for many insects, but both 
brown and white scale will live on them, 
and sponging is the best remedy. 
NOTHOCLANA. 
A pretty genus of Ferns, comprising both 
stove and greenhouse species. They are 
principally small growers, in appearance 
much like the Cheilanthes, to which they 
are nearly allied. 
For propagation and cultivation, see 
Ferns, general details of culture.

NYMPHAA. 
A magnificent genus of aquatic plants, 
most of which require a stove temperature. 
To do justice to them, and admit of enough 
kinds being grown to give variety, they 
should have a large tank with the water 
heated. The beauty of their flowers, com- 
bined with the length of time some of 
them keep on blooming (the hybrid N. 
Devoniensis, for instance, flowers for six 
months in succession) renders them ex- 
tremely desirable plants. Their cultiva- 
tion is simple, provided, as already said, 
there is a tank sufficiently large to accom- 
modate them. Some of the smaller species 
may with considerable success be grown in 
a large tub, placed in a warm part of the 
stove where there is plenty of light. 
They are increased by seeds or portions 
of the roots, the latter will in most cases 
be found the most convenient plan—cut 
the thick fleshy root-stock in good-sized 
pieces in the winter or early spring, before 
growth is made. Large wide pots should 
be used, and plunged in the tank, but yet 
raised sufficiently from the bottom to allow 
the leaves to rise somewhat above the 
crowns of the plants. Good yellow loam 
answers for them. Through the growing 
season the water should be kept regularly 
at 80°, or a few degrees over, and the tem- 
perature of the house ought to be such as 
required by the warm section of stove 
plants ; in winter it should not be lower 
than 55° for the warm species. Enough 
water should be regularly admitted to keep 
the whole sweet and clear, as if stagnant 1t 
soon becomes offensive. 
N. blanda. A white-flowered species 
from Trinidad. 
N. cerulea. A small-growing, blue- 
flowered species, that flowers in summer. 
Introduced from Egypt. 
N. cyanea. Bears blue flowers in summer. 
From India. 
N. devoniensis. A splendid kind, with 
deep rosy-crimson flowers. A garden 
hybrid. 
N. Lotus. A moderate-sized, white- 
flowered species, one of the most con- 
tinuous bloomers. From Egypt. 
N. rosea. A strong-growing, large- 
flowered, rose-coloured kind, from Last 
India. 
N. rubra. 
species, bearing large crimson blooms. 
comes from India. 
The following will grow in a lower tem- 
perature, but in other respects require 
treating similarly to the warm species :— 
N. dentata. Bears white flowers of large 
size, and in large numbers. From Sierra 
Leone. 
N. scutifolia. A beautiful blue-flowered 
species, from the Cape of Good Hope. 
This is one of the finest

CENOCARPUS. 
In these we have a genus of stove Palms, 
chiefly noticeable on account of the oil 
that some of the kinds yield, and which
