able occasions. They must, however, be shaded from strong sunshine, and! 
the newly-potted plants must be watered with extreme caution, neglect of 
this important matter being one of the causes of failure with this most 
beautiful family. 
OponTocLossuMs.—The dull moist.conditions has been to the liking of 
these plants, and it is astonishing the progress they have made this season. 
The house should be freely ventilated on all favourable occasions, the plants. 
shaded from sunshine, and the atmospheric conditions kept continually 
moist. The compost should be allowed to become moderately dry between 
each application of water to the roots, as in a temperature like this much 
harm may accrue should it remain in a saturated condition. The repotting 
may be continued as the plants arrive at the proper stage of growth, 
using the same material as advised in previous numbers. 
CyprIPepIUMS should by this time have all been repotted, but where 
there are small seedlings in need of more rooting space, they may have 
attention at any season, using material according to the section to which 
they belong. 
DENDROBIUMS.—Where this genus is grown extensively there will 
always be some species or hybrids requiring attention as regards repotting. 
Any plants of the evergreen section, of which D. thyrsiflorum is the best 
known, may have attention soon after the blooming period is past, and the 
plants have started new growth. Few plants make better specimens for 
exhibition than some of these; but one seldom sees them now as they were 
‘shown in the past. They delight in a good fibrous rooting material of 
lasting quality, and should never be overwatered. Whilst making their 
growth they should be placed in the warmest division, and when the 
growths are completed they should be rested in an intermediate temperature, 
and in a dryer atmosphere. There are many beautiful species of this 
section which are amenable to the’same treatment, as D. Farmeri, 
Dalhousieanum, chrysotoxum, and others. 
LEPTOTES BICOLOR is a pretty-terete 
repotted now that the flowering season is past, and the plants are making 
treated precisely in the same manner as a 
leaved species, which may be 
new roots. It should be 
miniature Cattleya. 
Puarus.—The later flowering varieties, both species and hybrids, may 
now be repotted if in need of new material. They will root well, and grow 
freely in the compost advised for Calanthes, and they may be potted in the 
same manner. During this season of growth a decidedly moist atmosphere 
should be maintained by keeping all the surroundings of the plants 
_ frequently damped down. 
Oncrp1ums.—Cool-growing On 
ramosum, Gardneri, concolor, and Marsha 
cidiums, such as O- Forbesii, crispum, 
llianum should be repotted when
