'210 GREEN-HOUSE REPOTTING. {March 



tifcy of new sorts may be obtained by cross impregnation be- 

 tween any two of very different colours; the seeds will ripen 

 in July-, when they may be sowu on light soil, and they will 

 flower the following season. Flowering plants require to be 

 greatly encouraged, and must be shaded during summer from 

 the violent noonday sun. (Soil No. 10.) 



CalotJidmnus, four species. This genus is named in allu- 

 sion to the splendid appearance of the branches, covered with 

 scarlet flowers, of curious construction, which come out of the 

 old wood. All the species are of -easy culture, and very like 

 dwarf pines. C. quadrijftda has the largest flowers; C. cla- 

 vdta the most abundant. They are all evergreens, and flower 

 from April to November, and are very desirable in a collec- 

 tion. (Soil No. 6.) 



Callicoma serratifblia, the only species, and remarkable 

 for tufted yellow heads of flowers, which come out at the 

 axils, and continue from May to July. The foliage is ovate, 

 lanceolate, deeply serrated and opposite. (Soil No. 6.) 



CanUllias. There are about eight distinct species of this 

 plant known in our collections; and the varieties of. japonic a 

 approach to one thousand, to which many are yearly added ; 

 but, unfortunately, their merits are not fully scrutinized before 

 they are sent forth to the floral world, under names represent- 

 ing and expressing every quality that is grand or beautiful in 

 floral imagination. Such has been the rapid increase of va- 

 rieties in Europe, and even in this country, that, in many 

 instances, three or four distinct plants have come out under 

 the same name; consequently, a great confusion of names has 

 been the result, which has caused much difficulty in attaining 

 the best of the names. The collections of this country were 

 kept comparatively pure till within the last few years, when 

 the anxiety of our cultivators to obtain variety caused them 

 to import from the French and German markets, which has 

 thrown the nomenclature into an almost impenetrable chaos. 

 But still we can unite in saying, " What species of plant is 

 there which better merits the intelligent and vigilant care of 

 the amateur and horticulturist?" The elegance of its form, 

 the beautiful verdure of its foliage, and the pure and brilliant 

 jolours of the large and elegant flowers, sufficiently justify the 

 idmiration of all. In fact, we may say, there is not a green- 

 house in which this lovely plant has not found a place, where 

 it stands in the first rank of floral population. To give a full
