EUPHORBIA. 
temperature of 70°; if they can be plunged 
in a bottom heat 10° higher, they will 
progress all the quicker. In this tempera- 
ture they will grow fast. Shade slightly 
during the hottest part of the day in very. 
bright weather, but in doing so do not 
‘darken the plants too much, or they will 
grow up weakly. Let them have a mode- 
rate amount of air early in the day, shut- 
ting it off in good time in the afternoon, 
and syringing overhead at the same time. 
They will bear during summer as much 
heat as the generality of stove plants. It 
will not be advisable the first summer to 
rest the smaller bulbs for flowering, as it 
will be better to get as much growth as 
possible. Early in August shift them 
into pots 2 inches larger than those they 
are in; continue to give them a liberal 
amount of heat and moisture, both at the 
roots and in the atmosphere, until autumn, 
when they will have made considerable 
progress. 
At this time, when the leaves are fully 
matured, cease shading, and gradually 
withhold water till the soil gets so dry as 
to cause the leaves to flag slightly ; do not 
let them be injured by the want of it, but 
give a little just to freshen them up, and 
again alternate the treatment by drying 
and then slightly watering them. Con- 
tinue this treatment for a month, during 
which time they can be kept in a night 
temperature of 55°, with a few degrees 
more warmth during the day ; then they 
may be well watered and placed in 10° 
more heat—if they can be plunged in 10° 
higher than this it will be still better. So 
managed they will quickly push up their 
flower-stems, and they should be encou- 
raged by being supplied with plenty of 
water at the roots and as much heat as is 
consistent with the diminished light of 
the season. Thus treated, when their 
blooming is over they will grow on slowly 
through the winter, and after their full 
development they may be again submitted 
to the drying and resting process, after 
which increase the temperature, give water, 
and treat them in every way as before. 
This alternate growing, resting, and flower- 
ing can be practised two or three times in 
the year with the best results without 
injuring the plants in the least. Do 
not at any time pinch them as regards 
pot-room. When the soil is well filled 
with roots they will be much benefited by 
a good soaking with manure-water once or 
twice a week. For general purposes mode- 
rate-sized plants in 12-inch or 13-inch 
pots will be found the most convenient, 
but where it is desired they may be grown 
on into specimens 6 feet across by simply

using pots or tubs proportionate in size. 
When large they make fine exhibition 
plants, their general appearance being such 
as to contrast well with their associates. 
E. candida differs little from E. ama- 
zonica, except that the flowers are much 
smaller and more elegant ; the foliage is 
also distinct. It is a native of the United 
States of Colombia, and a most desirable 
kind. 
E. Sanderiz has pure white flowers in the 
way of those of E. amazonica, 24 inches to 
35 inches in diameter ; it will be an accept- 
able addition to stove bulbous plants. It 
comes from New Grenada. 
Iysects.—Most of the pests that infest 
stove plants will live upon Eucharis, but 
from the nature of the leaves, they are 
more easily destroyed than on many plants. 
If thrips or greenfly make their appearance, 
fumigation will generally be found to be 
the best remedy, but from the regular use 
of the syringe these and red spider are not 
often troublesome. Should scale or mealy 
bug gain a footing they must be diligently 
sought for and removed by means of 
sponging, using a soft brush for the bases 
of the leaf-stalks where the bugs will be 
found to lodge ; for, if not destroyed, they 
will increase greatly and both disfigure the 
plants and do them serious injury by the 
constant cleaning process which their pre- 
sence makes necessary. 
EUGENTIA. 
These are evergreen plants varying in 
habit; some are shrubs, whilst others 
assume the proportions of trees. Only a 
few are worth growing under glass, and 
these cannot be counted as above second- 
rate in comparison with the many desirable: 
plants with which our greenhouses abound. 
They can be propagated and grown on 
sunilarly to Myrtles, which see. 
The two species best adapted for cultiva- 
tion in a greenhouse are :— 
E. apiculata. A white-flowered kind, 
from Chili. 
E. Ugni. Bears white flowers, and is 
also a native of Chili. 
EUPHORBIA. 
The genus Euphorbia comprises a large 
number of plants, existing in a wild state 
under the most opposite conditions of heat 
and cold, dry and moist atmosphere, from 
the Valerian-leaved (KE. valerianzfolia) 
of Siberia to the curious-crested angled E. 
lophogona, that flourishes in the hot regions: 
of Madagascar, the interesting E. orientalis, 
from the Levant, to the splendid scarlet-
