perfection.

* As most of the Odontoglossa require to be treated in the same way, I transcribe, from the ‘Guide to Cool-Orchid Growing’ (Reeve, 1864), the 
following instructions for the culture of the genus :— They will all succeed perfectly in a low lean-to house facing the north, the mean temperature of 
which need not exceed 60°. They should stand on a shelf of slate or stone, near the glass, but should always be protected from the direct rays of the sun. 
Constant humidity should be maintained by damping the shelves and floors, but the plants themselves will only require water in moderation, and what 
is given to them should pass away freely, for if it stagnates, or if the compost in which they grow becomes sodden, the roots will immediately decay. 
A gentle evaporation is greatly assisted by placing layers of moss—to be kept damp of course—on the shelves whereon the plants stand. Odontoglossa 
cannot endure wooden blocks, but will thrive in a compost of which one-half consists of small broken potsherds, the remainder being a mixture of 
shredded sphagnum (dusted with fine sand) and fibrous peat. About one-third of the entire depth of the pots may be filled with this mixture, the 
other two-thirds containing nothing but large pieces of broken pots, so as to admit as much air as possible to the roots. ‘I'he pots in which the plants 
are grown should stand on other pots (inverted) placed in saucers of water, in order to secure humidity and protect them from wood-lice. Nearly all the 
species flower during the winter or spring months, a circumstance that greatly enhances their value. Many, e. y. O. pulchellum, are deliciously fragrant, 
and the flowers of nearly all the species remain in perfection for weeks, whether left on the plants or cut for bouquets. In so vast a genus we shall, no 
doubt, meet with many idiosyncrasies, but nine-tenths of the species will flourish under the treatment indicated above, and which may be regarded as 
suitable to the majority of cool Orchids. Most Odontoylossa are, like the Masdevallias, very impatient of the knife, and cannot therefore be rapidly 
multiplied. They have also a peculiar aversion to fumigation by tobacco, which causes their leaves to fall off.”
