AUGUST, 1923.) THE ORCHID REVIEW. 243 
bulbs are grown sufficiently into the compost to escape injury by exposure. 
Where possible, it is advisible to select a position in the same house where 
more air and light can be admitted and less moisture afforded them 
atmospherically. This partial removal may be carried out as soon as the 
leaf at the extremity of the bulb is completed. Great care should be taken 
that plants which have completed their growth never get too dry at the 
roots, or receive any check that will cause them to finish too suddenly, as 
this frequently excites them afresh, instead of the buds at the base 
remaining dormant until after the flowering season is over. With a week 
or two of this treatment the young roots will have got well into the 
compost or around the sides of the pots, when they may be afforded cooler 
and drier conditions and less shading from bright sunshine ; they should 
be watered just often enough to keep the roots in a healthy condition, and 
to prevent undue shrivelling of the pseudo-bulbs. The new bulbs may be 
tied to neat stakes or they may be allowed to assume their natural pendant 
habit. Dendrobium Wardianum in particular blooms more freely, and its 
flowers are shown to better advantage, when the pseudo-bulbs are permitted 
to droop naturally. Other species of Dendrobiums and their numerous 
hybrids should be treated according to their various stages of development. 
Plenty of heat and moisture should be afforded growing plants. Aerial 
growths sometimes push forth from the pseudo-bulbs, these should be 
taken off, and, if it is desired to increase the stock, may either be potted 
singly in small pots, or placed several together in larger receptacles. 
Cuttings that were inserted as advised in a previous calendar, as they 
develop roots from the new growths, should be dealt with in a similar 
manner. After being potted they should be placed in a shady position. in 
the house until they are rooted in the compost, when they should receive 
Similar treatment to the established examples. 
Ca@Locyne.—Plants of Ccelogyne cristata are making rapid growth, and 
well established specimens will need copious supplies of water at the roots 
whenever the compost shows signs of dryness. An occasional watering with 
a weak solution of liquid cow manure will also be beneficial. Plants which 
have been repotted recently should be watered rather sparingly until the 
new roots have become established in the compost, and, during the whole of 
the first season after potting, should be afforded only clear water. The 
Surroundings of the plants should never be permitted to become dry. 
These conditions should be maintained until the pseudo-bulbs are matured 
and the flower scapes are developing, when the supply of water should be 
Sradually lessened. As plants of Coelogyne pandurata and the hybrid C 
Burfordensis pass out of flower, they should be given attention at the roots, 
Specimens that have outgrown their receptacles may have fresh rooting 
Materials afforded them as soon as new roots are observed to be pushing
