supply of water, and ought to be in every collection. (Soil 

 No. 11.) 



Cdnnas, about thirty species, several of them deserving 

 cultivation both for flower and foliage ; they are principally 

 datives of the West Indies. The finest are C. gigdntea, has 

 large leaves and orange flowers ; C. limbdta, flowers scarlet 

 And yellow ; C. discolor t has large cordate, acuminate leaves 

 of a crimson colour, CV iridiflora, has large crimson flowers. 

 They all, while in a growing state, require a liberal supply of 

 water, and being herbaceous plants, watering ought to be 

 given up about the first of November, and renewed in Febru- 

 ary, thus giving them a cessation which they require to flower 

 freely; but when water is constantly given, which is the gene- 

 ral plan in our collections, they continue to push weak shoots 

 and few flowers. They also do very well by planting them as 

 ornamental plants in the garden during summer, where they 

 bloom profusely, and their large roots can be placed in the cel- 

 lar all winter, where they will be free from frost. (Soil No. 

 12.) 



Cactus. This extensive genus is interesting, and varied 

 in character and habit; it is now divided into seven distinct 

 genera, according to their natural appearance and disposition. 

 We will describe a few of each genus, none of which going 

 under the name of Cactus, we will give them the six follow- 

 ing, premising that the time is not fur distant when this 

 family will be successfully cultivated in every parlour-window, 

 and the whole tribe will be sought for with more avidity than 

 any other class of plants that have ever been brought to 

 notice, not even excepting the Rose. They require a dry 

 heat, and win grow either in town or country, and are com- 

 pletely adapted 101 the denizen amateur, and will afford more 

 beauty and interesting display than can be imagined until 

 witnessed. 



Mamilldrias, about bounty species, and are those which 

 are covered with roundisn rearded tubercles, and with small 

 red and white flowers. M. coccinea, M. simplex, M. pusllla, 

 M. conica, M. stellata, and M. acanihbphlegma, are good 

 species, and will do well with water once a week during sum- 

 mer. (Soil No. 15.) 



Melocdctus, seven species, and are those that are roundish 

 with deep and many angles, with spines in clusters on the 

 top of the angle. M. communis is the Turk's cap, nampti
