reddish violet with deep red bracts. Brazil. 



N. fidgens. A compact-growing kind, 

 outer leaves deep green, inner ones red ; 

 violet-coloured flowers. Brazil. 



N. Innocenfii. Outer leaves stout and 

 broad, dark dull green above, red beneath ; 

 centre leaves orange colour ; flowers white. 

 Brazil. 



N. Laurentii. Leaves spotted dark brown 

 on a green ground colour ; flowers dull 

 purple. From South America. 



N. Meyendorffii. A strong-growing species 

 with leaves larger than those of some of 

 the family ; spiny on the edges, inner 

 leaves crimson ; flowers bluish purple. 

 Brazil. 



N. Scheremetieurii. 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. si^ectahile. 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 

 aft'ord food fur many insects, but both 

 brown and white scale will live on them, 

 and sponging is the best remedy. 



NOTHOCL^NA. 



A pretty genus of Ferns, comprising both 

 stove and greenliouse species. They are 

 principally small growers, in appearance 

 much like the Cherlanthes, to which they 

 are nearly allied. 



For propagation and cultivation, see 

 Ferns, general details of culture.

N. nivea. Tropical America. 



N. rufa. Tropical America. 



N. tenera. Mendoza. 



N. tomentosa. Mexico. 



GREENHOUSE SPECIES. 



N. EcJdoniana. South Africa. 

 N. Marantce. Southern Europe. 



NYMPH^A. 



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 lencrth 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 riart of the 

 stove" where there is plenty of light. 



They are increased by seeds or portions 

 of the roots, the latter vnll 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. Laige 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- 

 porature 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 it 

 soon becomes offensive. 



N. hlanda. A white-flowerea species 

 from Trinidad. 



N. cceridea. A small-growing, blue- 

 flowered species, that flowers in summer. 

 Introduced from Egypt. 



iV. 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 Egj-pt. 



N. rosea. A strong - growing, large- 

 flowered, rose-coloured kind, from East 

 India. 



N. rubra. This is one of the finest 

 species, bearing large crimson blooms. It 

 comes from India. 



The following wiU 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. 



iV. scutifolia. A beautiful blue-flowered 

 species, from the Cape of Good Hope. 



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
