then two feet high, and as much in dia- 

 meter. They will be fine objects either 

 for the greenhouse, when few other things 

 are in bloom, or for exhibition purposes. 



Winter Culture, As soon as the flow- 

 ers are all dead (if no seed is required), 

 the stems ought to be cut down, and the 

 plants either removed out of doors, or, 

 still better, into a cold pit. Plenty of 

 air should be given on all favourable oc- 

 casions ; and, as soon as the frost of win- 

 ter begins to appear, remove them into 

 the greenhouse, place them as near the 

 glass as possible, and keep them there 

 till the time of propagation arrives. Take 

 off the cuttings then, and throw the old 

 stools away. 



Forcing. On account of their impa- 

 tience of heat, Calceolarias, excepting a 

 few shrubby ones, do not force well. 

 These may be re-potted in January, and 

 put into a heat of 55 to 60. Give water 

 moderately, and allow the flower-stems 

 to grow from the first. They will then 

 flower in April and May. 



Diseases. The herbaceous varieties are 

 subject to a disease very like that which 

 has attacked the potato of late years. 

 They appear quite healthy, until dark- 

 brown spots appear on the leaves and 

 stems ; and in a week's time the disease 

 spreads, and the plants are dead. No 

 cure is known. As soon as it appears on 

 any plant, remove it at once, and throw it 

 away, because the disease is contagious, 

 and soon spreads to the healthy plants. 

 Too much wet at the root, or damp in the 

 house, will accelerate the disease. 



Insects. The most destructive is the 

 green fly (Aphis}. Whenever it appears, 

 fill the house with tobacco-smoke. Eed 

 spider (Acarus) will sometimes appear, if 

 the house be kept hot and dry. Dust 

 the leaves with sulphur where it is ob- 

 served. 



Calceolarias for bedding-out should be 

 propagated in the autumn, and kept in 

 the cutting-pots through the winter. Pot 

 them singly in the spring, place them in 

 a cold frame, and gradually harden them 

 off by May. Then plant them out in a 

 rich, light soil, where they are to flower.

CALECTA'SIA. (From kalos, beautiful, 

 and stachys, a spike. Calectasias are 

 branched herbs, with dry, permanent, 

 starry flowers, of a bright violet. Nat. 

 ord., Hushes [Juncaceae]. Linn., Q-Hex- 

 andria \-Monoyynia. Allied to Baxteria. ) 



Unless we had it on authority, we should not 

 take this for a rush, but a lilywort. Greenhouse

 C. cya'nea (blue-flowered). Blue. June. Aus-

 round. Nat. ord., a section of Compo- 

 sites [Asteracese]. Linn., 19-Syngenesia

Hardy annuals may be sown in the border, in 

 April; tenderer ones in a slight hotbed, and 

 transplanted in May. Greenhouse varieties by 

 cuttings ; sandy loam, and loam and peat for the
