try several years, we are not aware of its ever having bloomed. 
(Soil No. 11.) 
Cobsea scdndens, the only species. It is a climber of 
very rapid growth ; has been known to grow above two hun- 
dred feet in one summer; large bell-shaped flowers; when 
they are newly expanded, they are of a pale green colour, and 
change to dark purple : will grow in the garden during sum- 
mer, bearing a continual profusion of flowers, but will not 
stand frost. When this plant becomes too large in the house, 
do not cut it close to the root, except there is a young shoot 
arisiug to carry off the superabundant sap, for the old wood 
will not push, which will soon cause a mortification. 
The best method to adopt in such a case is, to turn back 
a shoot, and lay it in the ground to root, when it will be- 
come a young plant, which should always be done as soon 
as it appears unsightly. It does best to be planted in the 
ground, but will not give any satisfaction as to flowering in 
a pot. It will flower as an annual if sown in pots this 
month, and placed in a warm room or hot-bed, and planted 
into the garden about the middle of May ; it seeds freely.

CoroniUa, a very few are fine species in the green-house. 
('. (jlailca is a celebrated plant among us, as a free and early 
flowering shrub. 0. valentiana, and C. vwmidlis, are equally 
so ; flower from April to June, colour yellow ; papilionaceous 
flowers in clusters; agree best in summer with partial shade. 
Drain the pots well. (Soil No. 12.) 
Corrla, five species and several varieties, all very pretty 
dwarf shrubs, and flower profusely-; foliage ovate, cordate, 
and either rusty or downy beneath. G. alba, and G. riifa, 
have both white flowers a little tubular. G. pvlchilla is 
a very handsome, erect-growing plant ; flowers large and 
tubular, of a bright red colour, and grows freely. G. specidsa 
has been long admired as a splendid free-flowering plant; 
flowers same shape as G. pulchella, but more elongated; 
colour red and yellowish-green. G. virens is a very free 
grower, flowers same shape as the last two, colour entirely 
green; G. multiflora, red — C. bicolor, green and white — 
G. Harrisii, spotted. They are abundant flowerers, when the 
plants are well established; having a continued succession 
from November to June, possessing the valuable requisite 
of flowering through the winter, and ought to be in every
