cool division. Those with pendulous scapes, of which C. Devonianum and 
C. tigrinum may be cited as examples, are best cultivated in pans, and 
suspended about two feet from the roof glass. The idea of placing 
Cymbidiums in a high temperature has been proved erroneous, and more 
air should be admitted than was usually the case. Red-spider will some- 
times attack the foliage, and scale will congregate around the pseudobulbs ; 
the former can be destroyed by sponging, and the latter must be removed 
directly they make their appearance. A diligent search ought to be made 
at the time of repotting for scale insects. 
_ PHALz#Nopsis.—Where a representative collection of these glorious 
Orchids exists, it-is best to devote a house or division to their culture, but 
if the number of plants do not warrant this, a shady part of the stove or 
Warm house should be chosen. They may be grown in baskets, ordinary 
flower-pots, or teak-wood cylinders, which must be well supplied with 
drainage. A large quantity of soil is not needed, and the top layer should 
be clean sphagnum moss, which ought to be kept growing and be renewed 
directly it gets into.a bad condition. The collar or base: of the leaves can 
be raised slightly above the rim of the receptacle, and the compost worked 
between the roots. After being disturbed water must be afforded with 
great care, for if the soil be saturated the roots will decay and the leaves 
damp off. A position near the glass should be selected, and the plants 
must be shaded from all strong sunlight. Throughout the growing season 
a genial moist atmosphere is necessary, and any examples that were ne 
repotted may be liberally supplied with water. The leaves of Phalzenopsis 
are occasionally disfigured. with the ‘spot’ disease, which is usually 
brought about by excessive moisture at the base and improper ventilation. 
In regard to the latter, no hard and fast rule can be laid down, bee at 
must be admitted either from the bottom or top ventilators, whenever it can 
be done without chilling the plants. rs 
Puatus.—Both the species and hybrids of this genus are worthy of 
cultivation, and well-grown examples always prove useful for arranging 
with other plants, even when not in flower. They bloom at different 
periods of the year, so it will be quite obvious that all the plants are on 
tepotted at the same time. This is generally carried out when commencing 
their new growth, and the compost employed is principally good fibrous 
loam, with a little peat or fibre and sphagnum moss. It should be used 18

Liberal and frequent waterings are necessary during their period of activity» 
and when the plants have filled their receptacles with roots an occaslo : 
application of weak liquid manure will be beneficial. When the season 
growth is completed, only enough water need be given to keep the 5° 
moist. The Intermediate or Cattleya house is usually chosen, but they
