may be repotted whenever young roots are seen to be pushing from the 
base of the last-made pseudobulbs. Such cool-growing plants as L. 
pumila, prastans, Dayana and others are developing new growths. If a 
light position can be found for them in the Cool house they may remain 
there until their flowers show, but at that stage they will be the better for 
the increased temperature of the Intermediate house. These plants may be 
afforded fresh compost whenever they begin to make new roots. They are 
best cultivated in shallow pans that can be suspended close to the roof 
glass. These miniature plants delight in a reasonable quantity of light and 
air at all times, and a plentiful supply of water to the roots when in full 
growth. The thin-bulbed L. harpophylla should also be kept in a light 
position in the Cool house during the hottest portion of the year, and when 
the growths are nearing completion should be removed to the Cattleya 
house until their flowering period is past. 
OponToGLossums.—- Plants of any of the dwarf-growing section, such as 
O. Cervantesii, Galeottianium, madrense, Rossii, maculatum, and others 
that are in need of new rooting material may receive attention. They are 
all best grown in shallow pans suspended at the warm end of the Cool 
house. A similar compost to that advised for other Odontoglossums will 
answer their requirements. The compost must be placed firmly in the 
Pans, as all compost which contains osmunda fibre has the power to retain 
moisture in excessive quantities when loose. Water should be given care- 
fully until the roots have grown freely in the new compost, after which 
moisture should be liberally supplied until the growths are completed. 
While in full growth the plants will be benefitted by light sprayings over- 
head several times daily during hot weather. All these plants delight in a 
moist and humid position, which should be considered when affording them 
a position in the house in which they are grown. 
COCHLIODA AND ITS HYBRIDS.—C. Neetzliana, vulcanica, and sanguinea 
are best grown in shallow pans suspended from the roof of the Odonto- 
glossum house. As the numerous hybrids derived from this genera as one 
parent will succeed under the same conditions, they may be all treated 
alike. Any repotting that is necessary should be done whenever the young 
growths are about to push forth roots. With such a diversity of subjects 
the repotting of this family will go on right through the season. They 
should also be grown in well-drained shallow pans in the same manner as 
advised for the dwarf-growing Odontoglossums. 
DENDROBIUMS.—The cool-growing species, such as D. Jamesianum, 
infundibulum, and others, should, as they pass out of flower and start into 
growth, have attention as regards repotting, should it be necessary. Just 
as the young growths commence to push roots is the best season for this 
Operation. The tall growers do best in pots, the shorter ones in shallow
