CHAPTER XI 
SPECIALLY RARE AND VALUABLE PLANTS 
WHILE every plant in the collection should be given the 
best possible care and attention, it is advisable to keep 
the more rare and valuable specimens immediately under 
the eye of the grower. It is often the case that albinos, 
rare varieties, and new species are allowed to get mixed 
up in the general collection, and a plant that could not be 
replaced may be hidden by the commoner things which 
are not of so much consequence. In the case of the best 
spotted varieties of Odontoglossum crispum, albino Cattle- 
yas, and other exceptionally rare things, it is a good plan 
to arrange a batch of them together in the most suitable 
part of the house, or to place each on an inverted flower- 
pot at intervals along the staging, thus bringing them into 
prominence and facilitating the inspection of each at all 
times, Some use wire plant stands instead of inverted pots, 
but the moisture-holding flower-pots are preferable, if they 
are inspected occasionally to see that they are not harbour- 
ing insects. Albinos and fine varieties of Cattleyas and 
Lzlias could be grown in suspended Orchid pans or baskets, 
to take them out of the general collection, and so grown 
they would make better progress than if placed on the 
stages. In the case of any plant not making satisfactory 
growth it is often beneficial to place it on an inverted pot 
to bring it more prominently under notice.
