HEAT AND TEMPERATURE. 
those Plants that are natives of warmer climates, or 
within the tropics, as some species of Acacia, Ardisia, 
Burchellia, Cactus, Clerodendrutn, Strelitzia, Helio- 
tropium, Crinum, Daphne, Ixora, Euphorbia, Glox¬ 
inia, Manettia, and many others, which are what 
Florists term hot house or stove Plants, require a 
temperature of 60 to 80 degrees of heat, and many of 
them being natives of the Southern Hemisphere, 
flower in Winter, if properly treated, and would be 
desirable Plants for warm rooms. Most of the Plants 
grown in rooms and green houses are Plants from the 
temperate climates, as the Rose, Erica, Geranium, 
Fuchsia, Coronilla, Pittosporum, Calla, Camellia, Jas¬ 
mine, &c. These are what are termed Greenhouse 
Plants, and usually flower early in Spring and Sum¬ 
mer, resting a great portion of the Winter; these only 
require to be kept from freezing, or in a temperature 
from 40 to 60 deg., though most Greenhouse Plants, 
after resting, will commence growing in the tempera¬ 
ture of 50 deg. Several Plants that are apt to lose their 
leaves in winter and remain in a dormant state such as 
Hydrangea, Lemon-Verbena, Pomegranate, Erythrina, 
&c., will keep in a cellar together with the summer 
growing bulbous Plants as Tigerflower, Tuberose, 
Gladiolus, &c. If a furnace is put into the cellar they 
should be in the coldest part, where they will not 
freeze, and if they become very dry, they will want a 
little water occasionally, to keep them from perishing. 
Many kinds of herbaceous Plants as Primula, Auri¬ 
cula, Daisy, Violet, &c., will keep in a cool room 
about 40 deg., and as they are easily excited to grow, 
can be removed into a warm room as wanted, and will
