Since orchids never die, unless by accident, and never cease to grow, there is no limit to the bulk they may attain. Mishap alone cuts their lives short--commonly the fall or the burning of the tree to which they cling. Mr. Burbidge secured one, a Grammatophyllum, 'as big as a Pickford's van,' which a corvée of Dyaks could not lift. Some old collections even in Europe show prodigious monsters; in especial, I am told, that of the Duke of Northumberland at Alnwick. Mr. Astor has two Peristeria elata at Cliveden of which the bulbs are as large as an ostrich egg, and the flower stems rise to a height of nine feet! The most striking instance of the sort I myself have observed, if not quite the biggest, was a Cattleya Mossiae sent home by Mr. Arnold. It enclosed two great branches of a tree, rising from the fork below which it was sawn off--a bristling mass four feet thick and five feet high; two feet more must be added if we reckon the leaves. As for the number of flower-scapes it bore last season, to count them would have been the work of hours; roughly I estimated a thousand, bearing not less than three blooms, each six inches across. Fancy cannot rise to the conception of that gorgeous display. I doubt not that the forest would be scented for a hundred yards round.
Such giant Cattleyas are very rare in the 'wild state.' An orchid, though immortal, is subject to so many accidents that only species of very quick growth attain great age; these are less exposed to the perils of youth, naturally. From time to time, however, an Indian removes some plant which strikes him for its beauty or its size, and starts it afresh on a tree not too tall--and therefore young--in view of his hut. Thus it takes a new lease of life and grows indefinitely. I have not heard that 'white' peons are so aesthetic.
This Cattleya Mossiae had been rescued by an Indian. Mr. Arnold first saw it on his memorable search for Masdevallia Tovarensis. I must tell that episode to begin with.
More than thirty years ago a German resident at Tovar sent a white Masdevallia to a friend in England. There were very few species of the genus, few plants indeed, under cultivation at that time, and all scarlet. The novelty made a vast sensation. For a good many years the owner kept dividing his single specimen, and putting fragments on the market, where they fetched a very long price. Under such circumstances a man is not inclined to tell where his treasure comes from. At an earlier date this gentleman had published the secret so far as the name 'Tovar' went. But there are several places so called in Spanish America, and importers hesitated. At length Mr. Sander made up his mind. He sent Mr. Arnold to Tovar in New Grenada.
