383 



N. Marliacea-chromatetta(fig. 478). — Soft canary-yellow 

 flowers, 4—6 inches across, with orange stamens. Very 

 free in errowth and flowers. 



Fig. 478.— Nymphaea Marliacea-chromatella. 



N. Marliacea-flarnmea. — Rich crimson -purple, suffused 

 with white or lilac. 



N. Marliacea-ignca. — A moderate grower, but one of 

 the deepest and richest in colour. Rich glowing crimson, 

 with orange centre. 



jV. Marliacea- sanguined. — Bright reddish-crimson. 



N. nivea. — White flowers ; fragrant. 



N. odorata. — The Sweet-scented Water-Lily of North 

 America, with shapely white flowers, smaller than those 

 of iV. alba. In the hands of M. Marliac it has given 

 rise to a very beautiful series of varied forms, having 

 shapely incurved flowers and blunt or spoon-shaped petals. 

 They are all suitable for small tanks, or the margins of 

 shallow ponds. The flowers close early in the afternoon. 



Var. exquisita. — Soft rosy-carmine flowers. 



Var. minor or pumila.— Small, with white flowers. 



Var. rosea.— Flowers larger than the type, elegantly cup- 

 shaped, clear soft rose-pink. 



Var. rubra. —Flowers dark-rose. 



Var. sulphured. — Similar to JV. M.-chromatella, but flowers 

 deeper yellow, with more pointed petals; fragrant. 



Var. grandiflora.— Stronger and larger than the last. Flowers 

 5-7 inches across, with petals like a Cactus Dahlia. Colour 

 clear yellow, with orange centre. 



The preceding two kinds have large brown-marbled leaves, 

 and are quite different to the other forms of JV. odorata. 



N. pygrnwa. — The very smallest of its race, the leaves 

 being only 2 or 3 inches wide* and the flowers less. 

 The latter are peculiar in having the segments arranged 

 squarely, hence the synonym N. tetragona. 



Var. helvola.— Similar in habit to the last, but having bronzy- 

 marbled leaves and soft canary- yellow flowers. Both are 

 suitable for small aquaria. 



N. Richardsoni(f\gA79). — Similar in habit to N. tuberosa. 

 Flowers pure white, standing well above the water, the 

 sepals and outer petals drooping so that they form a per- 

 fect globe. 



N. Robinsoni. — A Marliac seedling of a soft-red shaded 

 with buff or yellow, and of medium vigour. 



N. scutifolia. — A South African plant with sweet- 

 scented blue flowers. Differs from N. stcllata in having 

 broader blunter petals. Stove, or warm water. 



N. Seignouretii. — Pale-yellow, shaded or flushed with 

 carmine. 



N. stcllata (Starry Blue). — This is the common African 

 species. It may be wintered in warmth, and placed in a 

 sunny tank in May or June in the open air. Var. cyanea 

 is a pale-blue form from India. A long-stalked larger 

 pale form is known as the "Berlin variety", and var. 

 versicolor is white flushed with -red. N. stellata is often 

 miscalled iV. ccerulea. Var. zanzibarensis is the largest 

 and best form, the flowers being coloured rich purple- 

 blue, and often measuring 7 inches across. There are 

 paler smaller forms of it. 



N. Sturtevantii. — An American seedling from N. devo- 

 niensis, bearing very large and shapely flowers of a pale, 

 clear, rosy-red colour. 



N. tkerrnalis. — Leaves sharply toothed. Flowers pure 

 white, with a vinous odour. Stove or warm tank, being 

 found in the warm river Pecze, hence its specific name. 



N. tuberosa. — A free-growing North American species, 

 with ample foliage and large white flowers, produced later 

 than those of N. alba. Similar in habit to N. candidis- 

 sima, but the root-stock is creeping, bearing oblong tubers. 



N. Wm. Doogue. — Flowers 5-6 inches in diameter, 

 cup-shaped, and of a clear shell-pink colour ; petals very 

 broad and of great substance. An American seedling. 



N. Wm. Falconer. — One of the largest and best. 

 Flower 6 inches in diameter, garnet or ruby crimson, 

 with orange -yellow anthers. Being intermediate between 

 N. Leydekeri and N. Marliacea, it grows well, but is not 

 too robust. Leaves red when young, turning to olive- 

 green with red veins. An American seedling. 



Peltandra virginica. — The " Arrow Arum " of the 

 N.E. American woods, which may be grown in a sunny 

 sheltered pool, though it is not very showy. 



Pistia stratiotes (Water Lettuce). — A floating plant 

 with thick-ribbed, soft, light-green leaves. Subtropical,

but may be grown outside in sheltered tanks or vases 

 during summer. 



Pontederia cordata (Pickerel Weed). — Forms tall tufts 

 of heart-shaped leaves and blue flowers on slender 

 stems. 



P. crass ipes (the Water Hyacinth) (fig. 480). — A floating 

 tufted plant with inflated leaf-stalks, reniform leaves, and 

 spikes of rose-purple Hyacinth-like flowers. It thrives 

 in a sunny pool out of doors in summer, and multiplies 

 rapidly. 



Ranunculus Lingua (Largest Water Buttercup). — A 

 free and tall-growing plant 3-6 feet high, with narrow
