230 THE ORCHID REVIEW. [JULY, 1913. 
hanging pans, but in either case it is important that the plants receive 
plenty of light. They should be potted firmly in the usual Dendrobium 
compost. When growing actively the plants should be liberally supplied 
with water at the roots, but when growth is completed much less will 
suffice. During the winter months they are best removed to a light position 
in a cool Intermediate house. 
Oncipiums.—During the present month there are many of the cool 
Oncidiums, such as O. Forbesii, crispum, Gardneri, concolor, Marshall- 
ianum, and others which may require attention as regards repotting. They 
should be repotted when the young growths are from three to four inches 
long and are about to emit new roots. The flowers of these species are 
produced on pendulous racemes, and are delightful Orchids when in bloom. 
They all succeed in shallow pans, and resent having a large amount of 
compost placed about their roots, therefore moderate-sized pans should be 
used with a good supply of drainage. A similar compost to that used for 
Odontoglossums will answer their requirement, but slightly more half- 
decayed oak leaves may be added. The warmer-growing Oncidiums, such 
as O. Lanceanum, luridum, carthagi , and others of this section may 
also be afforded fresh rooting material as they reach the desired condition. 
These plants revel in a light position in the warmest house, and whilst the 
roots are growing actively they should have liberal supplies of moisture, and 
the plants may be sprayed freely during bright days, but during their 
resting season water should be sparingly supplied, as their fleshy leaves are 
capable of withstanding a reasonable amount of drought without injury. 
The cool O. macranthum and allied species that are developing flower 
spikes should be given water at the roots whenever they become dry until 
their flowers open. The inflorescences of all Oncidiums should be removed 
soon after all the flowers are fully developed, as they exhaust the energies 
of the plant. Oncidiums include some of the most beautiful and interesting 
of Orchids, and it is a pity that so little progress has been made in their 
culture as compared with most other groups. 
GENERAL REMARKS.—Since my last notes were written another mile- 
stone in horticultural history: has been passed. Those who have had 
the good fortune of seeing the series of shows held in the Temple Gardens 
are fully aware what an important influence the latter have had upon 
Orchid culture in this and other countries. At the recent show at Chelsea 
Orchids were one of the most prominent features of one of the greatest and 
best shows ever held, which must be highly satisfactory to those who, like 
myself, look to their popularity for a livelihood. If the strides made during 
the next twenty years equal those made during the last it is hard to conceive 
what will be attained, and in the hybridisation and cultivation of Orchids 
there is an unlimited field of operations.
