March.'} GREEN-HOUSE REPOTTING. 201 



scriptive list of many of the finest, with a faint outline of their 

 characters and general treatment, which will prove a deside- 

 ratum for those who are inexperienced, and strangers to the 

 beauties, pleasures, and arts of exotic flora culture. Therefore, 

 if you have any of the following plants that you are desirous 

 of encouraging, they should be repotted this or next month at 

 the latest. Large plants will not require it if they were done 

 in August. Pots one size larger than those that they are in 

 are sufficient. 



Acacias and Mimosas being now united into one genus, 

 there are above two hundred species. About one hundred 

 and thirty belong to the green-house. Among such a beau- 

 tiful family, both for elegance of flower and beauty of foliage, 

 it will be difficult to specify the most handsome and desirable 

 for this department. A. dealbdta, A. glaucescens, A. verti- 

 ciUdta, A. florabunda, A. diffusa, A. armdta, A. decipiens, 

 A. fragrdns, A. jmlchella, A. lophdntha, A. decurrens, A 

 ptibescens, A. myrtifblia, A. conspicua, A. linearis, &c. 

 These will afford a great variety of foliage, and are very de- 

 sirable, flowering principally in winter, or early in spring. 

 The flowers of those belonging to the green-house are of a 

 yellow or straw colour; the most of those that are red or pur- 

 ple, with the celebrated medicinal species, belong to the hot- 

 house, for which see May. There are some of the species very 

 subject to the white scaly insect, which must be attended to, 

 that they may not get to any extent. (Soil No. 1.) 



Agapdnthus, three species. A. umbelldtus, with bright 

 blue flowers, is very celebrated, and well known in the col- 

 lections of the country. There is a variegated variety of it 

 highly desirable, the foliage being white striped, and frequently 

 the flower stem and the flower A. dlbidus has pale white 

 flowers, and as yet rather scarce. They have very strong 

 roots, and require plenty of freedom. Plants are always large 

 before they flower, and when the pots, by frequent shifting, 

 become inconvenient, the plant should be divested of all the 

 earth, and, if too large, divide it, cutting off the strongest of 

 the fibres; then they will admit of being put into smaller pots. 

 If the above operation is performed in August or September, 

 it will not retard their flowering, which, when well grown, is 

 very handsome, the flower-stem arising about three feet, and 

 crowned with twenty or thirty blossoms, continuing to bloom 

 successively. (Soil No. 12.)
