3Iarch.'] green-house — repotting. 197 



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

 their characters and general treatment, which will prove a 

 desideratum 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 Mimoms 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 beauti- 

 ful 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, dealhdfa, A. (/laucSscens, A. verti- 

 cilldta,, A.Jlorabitnda, A. diff'usa, A. armdtaj A. decijpienSj 

 A. fragrdnSj A. 'pidcMlla^ A. lophdnthaj A. deciirrens, A. 

 piihescens, A. mi/rtifoUa, A. conspicnaj A. linearis, &c. 

 These will aff'ord 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 color ; 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.) 



Ac/ajxinthuSy three species. A. umhelldtus, 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 fre- 

 quently the flower stem and the flower A. dlhidus 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 fre- 

 quent shifting, become inconvenient, the plant should be 

 divested of all the earth, and, if too large, divide it, cutting 

 cfi" 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.)
