to well-drained 6-inch pots, using equal parts of fibrous loam, rough peat, leaf soil 

 and silver sand. Pot firmly; arrange the plants in a moist sunny position in an 

 ordinary plant stove. Apply water freely during the greater part of the year, keeping the 

 plants somewhat dry at the roots during the winter. Young, single stemmed, plants are 

 usually preferred to large specimens, and a fresh stock should be raised every spring 

 to take the place of old plants that may be thrown away after flowering. 



nymphjea. — This genus not only comprises the common Water Lilies, but also 

 several species that are worthy of a place among stove aquatics. Foremost among 

 these must be placed N. coerulea, syno. N. stellata, Tropical Asia ; leaves nearly 

 entire ; flowers blue, delicately scented and produced abundantly during the summer. 

 The flowers of N. c. cyanea, India, are also blue ; while those of 1ST. c, zanzibarensis, 

 Zanzibar, are of a still deeper shade of blue ; this is considered " one of the freest 

 flowering and most beautiful of all the Water Lilies." N. Lotus, Egyptian Lotus, once 

 sacred to Isis, a goddess of the ancient Egyptians, has peltate, sharply serrated leaves • 

 flowers large, red or white, with the sepals red at the margins. N. L. dentata is a 

 large pure white form, IN". L. rubra forming a good red companion. All are propagated 

 by seeds, which should be sown thinly in pots of rich soil, and immersed 8 to 12 inches 

 deep in water kept warmed to a temperature of 65° to 75°. If the seedlings are early 

 reduced to one in a pot, and given a liberal shift when they require it, they will grow 

 strongly and flower the same season. When the leaves die down the temperature of the 

 water should be lowered 10°, the plants surviving till the spring, even if the water is 

 drawn off altogether. In February or March, tree the roots of old soil and return them 

 to either large pots or tubs, filled with two parts rich fibrous loam to one part of well 

 decayed manure. Immerse 8 to 12 inches deep in the water, warmed as before. 

 Nympheas should have all the sun and light possible. 



Oranges and Citrons. — See Conservatories. 



otjvikandra, or Lattice-leaf Plant, so called from the peculiar formation of the 

 leaves ; an aquatic perennial, allied to Aponogeton. O. fenestralis, Madagascar, forms 

 leaves 6 to 18 inches long, and from 2 to 4 inches broad, these spreading out nearly 

 horizontally on the surface of the water. They are merely a network of vascular tissue 

 resembling a lattice window. Flowers, greenish- white, the flower stem splitting at 

 the top into two spikes. Plants are raised by sowing fresh seed in small pots of 

 loamy soil, immersing them in water heated to a temperature of 75°. Increased by 

 division of the roots m February or March. Grow the plants in small pots of loam
