Night-Flowering Nymph^eas. — N. amazonum, a native of 

 South America, has fragrant yellowish - white flowers, below 

 medium size. The plant is of moderate growth, with smallish

 flowers of the largest size ; it is of vigorous growth, with large 

 purplish-green leaves, deeply toothed at the margins, and marked 

 on the upper surface with irregular-shaped dark brown blotches.

 allied to the 

 Lotus section, 

 and increases 

 freely by means 

 of tubers. N.

 hybrid raised 

 in the Berlin

 bearing parent. 

 The flowers

 hue towards 



the base of the petals. The plant is of robust habit, with large 

 leaves, scalloped, and sharply serrated at the margins ; it is a 

 free-flowering and very desirable hybrid. N. Deaniana is a 

 hybrid of American origin, producing large clear rosy-pink flowers 

 very freely ; it is of vigorous growth, with large bronzy leaves, 

 and belongs to the Lotus section. N. devoniensis (Fig. 606) is a 

 reputed hybrid between N. Lotus and N. L. rubra, the latter 

 being the seed-bearer; it is stated to have been raised at Chats- 

 worth in 1851, and named in honour of a former Duke of 

 Devonshire. It is a magnificent Water Lily, with flowers of 

 the largest size and of a rich deep red. The freedom with 

 which it flowers, combined with its robust habit, entitles it
