March."] 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 Mvmbms 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. y/aucescens, A. vcrti- 
i-iUdfa, A. Jiorabiinda, A. diffusa, A. armdta, A. decipiens, 
A. fragrans, A pidcliella, A. lophdntha, A. deciirrens, A. 
piibescens, A. myrtifulia, A. conspictia, A. linearis, kc. 
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 gi'een-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.) 
Agapdntlms, three species. A. vmhdldtus, 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. 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 fre- 
quent 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.)
