206 GREEN-HOUSE — REPOTTING. [March. 



red; C. maculafa, superbly marked with red or crimson. 

 There are many others of very great merit of the shrubby 

 kinds cuhivated in Europe, such as whites of different shades, 

 dark crimsons, with white capes, and others blending into 

 almost every description of color and character. Any quan- 

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

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

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

 flower the following season. Flowering plants require to be 

 greatl}' encouraged, and must be shaded during summer from 

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



CalotlichiDim, 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. quadnffida has the largest flowers ; O. 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.) 



Calh'coma served i/oUa, 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.) 



(^amdllias. There are about eight distinct species of 

 this plant known in our collections; and the varieties of 

 Jcqjonica 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 representing and expressing every quality 

 that is grand or beautiful in floral imagination. Such has 

 been the rapid increase of varieties 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 luis been the result, which has 

 caused much difiiculty in attaining the best of the names. 

 The collections of this country were kept comparatively 

 jture 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 no- 

 menclature into an almost impenetrable chaos. But still 

 we can unite in saying, " AMiat species of plant is there 

 which better merits tlic intelligent and vigilant care of the
