SCILLA 



yellowish white, is fairly large, and com- 

 prises many hardy annuals and perennials, 

 propagated by seed and division of the 

 roots. The most noteworthy perhaps 

 are Scabious arvensis, or " Gipsies' Rose," 

 the lilac scabious of the cornfields, and 

 S. atropurpurea, or ''Mournful Widow," 

 a dark purple species often found in gardens. 

 They are chiefly useful as cut flowers for 

 nosegays. 



Scale. 



An insect that infests and does much in- 

 jury to many trees and plants both under 

 glass and out of doors. The males are in the 

 form of small flies. The females look like 

 small plates or scales whence the name- 

 fixed to the leaves and bark, and appearing 

 like flat grey or brown spots on them; 

 Different trees and plants are infested by 

 different kinds of scale, and each has its 

 distinctive name. Apples, pears> peaches, 

 nectarines, roses, camellias, oranges, 

 lemons, acacias, palms, and oleanders, are 

 especially susceptible to injury from them. 

 They are destroyed by the application of 

 Strong soapy water in the proportion of I

 the proportion of ^ gill to I gallon, lye of

SchizantllTlS (not. ord. Solana'cese). 



A genus of half-hardy annuals with 

 flowers of pretty shape, variously coloured, 

 from which it has obtained the name of the 



SCILLA NUTANS, OR BLUEBELL. 



Butterfly Flower, or Fringe Flower. The 

 plants are well adapted for pot culture in 

 good rich soil, and as border plants. If 

 seed be sown under protection in autumn 

 the plants raised will flower in the green- 

 house or conservatory in early spring. The 

 species chiefly sown in open ground as a 

 border plant is Schizanthus pinnatus, 

 which, with its varieties, is as hardy as 

 all the ordinary hardy annuals. 



Scilla (nat. ord. Lilia'cese). 



The species of t'ds genus are very 

 numerous, the best known being Scilla 

 nutans, otherwise the Bluebell, Harebell, 

 or Wild Hyacinth. They are spring flower- 

 ing, bulbous plants, and as such their 

 culture and propagation is the same as for 

 bulbs, which see. S. Sibirica^ or Siberian 

 Scilla, is equally well suited for pot culture 

 or growing in the open ground. S. bifolia 

 pracox is another useful species, but those 

 that are most in use and their varieties will 

 be best ascertained by reference to the bulb
