INTRODUCTION.

At the time (1864) when this Monograph was commenced, the successful application of the system of cool treatment to Orchids accustomed to a moderate temperature in their native haunts gave a fresh impulse to the cultivation of that charming tribe of plants. By its means, what might almost be regarded as a new Orchid-world, teeming with interest and beauty, was suddenly brought within our reach. A fresh field was opened to the enterprise of collectors, the spirits of cultivators revived, and the hopes of botanists mounted high. Foremost among the spoils that we sought to secure, stood the various members of the genus Odontoglossum, which from the days of Humboldt[^[1]] and Lexarza, was known to abound in species pre-eminent for the loveliness and delicacy of their flowers but which had hitherto mocked the utmost efforts of our most skilful growers. For although (thanks to the labours of Warczewitz and Lobb) the Horticultural Society and Messrs. Veitch had more than once received large consignments of Orchids—among which were many Odontoglossa—from the mountain ranges of New Grenada and Peru, they had invariably succumbed under the stifling atmosphere to which, in common with the denizens of India, Guiana, or Madagascar, they were remorselessly consigned. Here and there, indeed, an accidental success was achieved in a greenhouse, but the hint was turned to no account, and as a rule—notwithstanding the repeated warnings and remonstrances of Mr. Skinner, Warczewitz, and others—for thirty years we persisted in the incredible folly of growing "cool" Orchids in "hot" stoves; so deeply rooted in the minds of horticulturists was the original prejudice! But it yielded at last, and no sooner had a few houses—constructed and managed on the cool-culture system—made it clear that the Orchids of temperate regions were prepared to submit to the skill of the cultivator, than a general raid was made upon the more accessible countries in which they were known to abound—more especially certain districts in Mexico and New Grenada. To the latter country, collectors were simultaneously sent off by the Horticultural Society, who despatched Mr. Weir; by Mr. Linden, of Brussels; and by Messrs. Low, of the Clapton Nursery; and all these rival envoys, much to their own mortification and chagrin, found themselves sailing for the same destination in the same steamer on the same errand!

It was now that the idea occurred to me of devoting a work of adequate dimensions to the illustration of the particular genus, which from the dried specimens in our herbaria, the plates in Pescatorea, the figures of Humboldt, and the descriptions of travellers was evidently destined to hold the first place among all the numerous company of cool Orchids; and thus began the present Monograph. I had expected that after the work of importation had fairly commenced, not only would the species described by Lindley and Reichenbach be easily obtained, but that along with these a multitude of others entirely new to science would likewise be received. In this respect, however, the results have scarcely come up to expectations; a circumstance that is partly to be accounted for by the difficulty attendant on their importation,[^[2]] but which is owing, I grieve to say, in a far greater degree to the untimely deaths of those zealous collectors, Bowman and Pearse, who, when in the very heart of the cool Orchid regions of Ecuador and Peru, succumbed under the pressure of their arduous labours. In Mexico, from which much novelty was expected, little has been added to the number of Odontoglossa previously known, and the same may be said of Costa Rica, notwithstanding the vigorous exertions of Mr. Endries. But in these countries it is evident that the genus is not so fully developed as in the mountain ranges of New Grenada, Quito, and Peru. From the latter country little indeed has yet been received, although the eastern slopes of its Andean chain are probably richer in species of unknown or unimported Orchids than any other portion of the globe. But we must await further improvements in the navigation of the affluents of the mighty Amazon, before we can hope to receive any large instalment of these much-coveted treasures.
