of peat soil, and set into a similar frame. Whether grown in 

 pots or planted out, they do not at all like to be disturbed, 

 and should therefore be replanted or repotted as seldom as 

 possible. It is a remarkable as well as beautiful family, and 

 is worth any trouble to secure its successful cultivation. All 

 pretty. 



CYRTANTHUS. [Amaryllidacese.] Handsome bulbous 

 plants. Soil, strong, rich, but open loam. Propagated by 

 offsets. The evergi^een species require to be kept growing 

 in a warm greenhouse in winter ; the rest diy and at 

 rest. 



CYSTOMIUM. [Polypodiacese.] Greenhouse evergreen 

 fern. Soil, turfy peat and loam. Increased by division. 



OYSTOPTERIS. Bladder Feen. [Polypodiace^.] A 

 very pretty genus of small-growing ferns, with delicate annual 

 fronds, of from three to twelve inches in height. They grow- 

 well on rockwork, or in pots among turfy soil, intermixed with 

 lumps of brick or freestone, and well drained. They are mul- 

 tiplied by division of the plants. C. alpinum, C. bulbiferum, 

 C. fragile, and C. montanum are the principal. 



CYTISUS. [Leguminosse, § Papiliouaceae.j Elegant 

 and for the most part showy shrubs and small trees. C 

 lahurnum and C. alpinus are well-known free-flowering trees ; 

 and though the most familiar and common, are the most 

 beautiful of the whole family. They may be raised from seeds, 

 which need only be sown on the common open ground and 

 raked in, where they may be thinned to proper distances, two 

 or three inches apart, and remain the first season ; the next 

 they may be planted out in rows, a foot from plant to plant, 

 and two feet fiom row to row. As all these trees are wanted 

 as standards, whether for their own sakes or for stocks on 

 which to graft or bud other varieties, therefore the side-shoots 

 but the top two or three should be rubbed off while merely 

 buds. When they are tall enough their heads may be allowed 

 to grow and bloom, because those with the largest and hand- 

 somest racemes of flowers may be saved for Laburnums, and 

 the others may be worked with the different species of Cytisus, 

 some of which are white, others yellow, and many are of 

 different forms and habits, but all make good standards. 

 Some of them have small racemes of flowers, others bloom
