362 THE ORCHID REVIEW. (DECEMBER, {[912- 
the Lelia is cinnabar-orange. In habit, too, the hybrid most resembles the 
Diacrium parent. It will be noticed that the Lelia flower was taken from 
a different print, but all are from the same negative. White and orange 
are well known to be difficult to photograph together, and the Lelia Hower 
was taken from a rather lighter print, the outline of the flower being rather 
clearer. It is interesting to note that we have now four generic combina- 
tions with Diacrium, namely, Dialelia, Diacattleya, Diacatlelia, and 
Epidiacrium. The three latter were raised in the collection of Sir Jeremiah 
Colman, Bart., Gatton Park, Reigate.

WE have again reached the season of the year when, owing to climatic 
conditions, things generally are as bad as possible for the cultivation of 
Orchids. What with fogs, dark and short days, an outside atmosphere 
heavily charged with moisture, and a very low temperature, all of which 
are detrimental. to the plants, the cultivator has enough to contend with, 
Daylight is now a scarce commodity, and, therefore, it is necessary that 
the plants should receive every particle of light possible. 
The remarks made last month as regards temperatures, watering, 
ventilation, and atmospheric moisture still hold good, and no pains should 
be considered too great to satisfy the wants of the plants at this season. 
The painstaking thoughtful grower will always be in advance of the slip- 
shod one, who leaves so many things to chance, and I often think that the 
plants themselves appreciate the cultivator who anticipates their require- 
ments some time beforehand. 
Although the past season has been far from an ideal one, owing to the 
lack of light and sunshine, the plants have made much finer zrowth than at. 
one time seemed possible. The growths not being so fully matured as after 
the bright weather of last summer, care must be taken that no serious 
fluctuations of temperature are allowed, or much harm may accrue. 
CATTLEYAS AND THEIR ALLIES.—At this season of the year not many 
species of these beautiful plants are in flower, but owing to the strides made 
by the hybridist, it is now possible to have bigeneric Lzliocattleyas the 
whole year round, and the great diversity in shape and colour of their 
flowers makes them most interesting and for gorgeous colouring unsurpass- 
able. With C. labiata and its varieties over, C. Percivaliana and C. 
Trianz will be the next species to flower, and those plants that are already 
showing flower buds in their sheaths should be placed in the lightest. 
position available, and have water afforded them whenever they become: 
dry. These remarks also apply to the whole of this family, both species: 
and hybrids, that are in a similar condition.
