tings in sand in a close frame, with bottom-heat. Loam, 



lumpy peat and sand.

CERCIDOPHY'LLUM. (From Cercis, the Judas-tree, 

 and phullon, a leaf ; the leaves having a general simi- 

 larity. Nat. ord. Trochodendraceae.) 



A small tree or shrub, hardy in the more favoured 

 parts of Britain and Ireland, or on a wall in the latitude 

 of London. Seeds, layers. Ordinary, well-drained soil. 



C. japo'nicum (Japanese). 8. Apetalous. Japan. 1889. 



CE'RCIS. Judas-tree. (From kerkis, a shuttlecock ; 

 the name given by Theophrastus. Nat. ord. Leguminous 

 Plants [Leguminosae]. Linn. lo-Decandria. i-Mono- 

 gynia.) 



The wood of C. Siliqua' strum is beautifully veined, and 

 takes a good polish. Hardy deciduous trees. Seeds, 

 sown in a gentle hotbed, in spring ; hardened off, and 

 pricked out into a sheltered situation ; the varieties by 

 grafting. In the south of the island they do well in 

 sheltered places, on a lawn ; in the north, they require 

 a wall.

CERCOCA'RPUS. (From kerkos, a shuttlecock, and 

 carpos, a fruit. Nat. ord. Roseworts [Rosaceae]. Linn. 

 12-Icosandria, i-Monogynia. Allied to Geum and 

 Purshia.) 



There is no unwholesome plant in this order ; and the 

 strawberry, raspberry, and the blackberry or the bramble, 

 are the nearest plants in affinity to the rose itself. Then 

 come the Potentilla, Geum, and Agrimonia, among which 

 stands Cercocarpus, followed by the Spiraeas and Quil- 

 laiads. Greenhouse evergreen shrubs. Cuttings of green 

 shoots in sand, under a glass, in a little heat. Peat and 

 loam. Winter temp., 40 to 45.

CE'REUS. Torch Thistle. (From cereus, waxy ; re- 

 ferring to the fact that some of the spines are as pliant 

 as soft wax, while others are as brittle as wax tapers. 

 Nat. ord. Indian Figs [Cactaceae]. Linn. 12-Icosandria, 

 i-Monogynia.) 



Cuttings, at any time, of either old or young shoots ; 

 the latter are the best, if the base of the cutting is well 

 dried. Instead of inserting them firmly in sand, they 

 do best when laid among rough material, such as peat 

 charcoal, leaf-mould, and brick and lime-rubbish. They 

 are generally described as stove plants ; but, unless when 

 they are just making their wood, they will endure a 

 very low temperature, if kept dry. Unless for the winter- 

 flowering varieties, and those desired to bloom at that 

 season, no water will be requisite from October to March, 

 if kept cool. Sandy loam, turfy peat, half-parts of lime- 

 rubbish and dried cow-dung. Water freely when grow- 

 ing, and when in bloom. Summer temp., 55 to 85 ; 

 winter, 35 to 50.
