At the far end of the house stands another piece of rockwork, another little cascade, and more marvels than I can touch upon. In fact, there are several which would demand all the space at my disposition, but, happily, one reigns supreme. This is a Cattleya Mossiæ, the pendant of the Catasetum, by very far the largest orchid of any kind that was ever brought to Europe. For some years Mr.
Beneath the staging you may see myriads of withered sticks, clumps of shrunken and furrowed bulbs by the thousand, hung above those leaf-beds mentioned; they are "plumping" in the damp shade. The larger pile of Catasetum there are two may be four feet long, three wide, and eighteen inches thick; how many hundreds of flowers it will bear passes computation.
It grew and grew very fast, never receiving water unless by the rarest accident, until those experts could identify a healthy young Catasetum. And there it has flourished ever since, receiving no attention; for it is the first rule in orchid culture to leave a plant to itself where it is doing well, no matter how strange the circumstances may appear to us.
No orchids, however, give more material for study; on this account Catasetum was a favourite with Mr. Darwin. It is approved also by unlearned persons who find relief from the monotony of admiration as they stroll round in observing its acrobatic performances. The "column" bears two horns; if these be touched, the pollen-masses fly as if discharged from a catapult.
Strange incidents occur continually in this pursuit, as may be believed. Nine years since, Mr. Godseff crossed Catasetum macrocarpum with Catasetum callosum. The seed ripened, and in due time it was sown; but none ever germinated in the proper place. A long while afterwards Mr. Godseff remarked a tiny little green speck in a crevice above the door of this same house.
He will be apt to cry, "Would that the difficulties and perils were infinitely graver so grave that the collecting grounds might have a rest for twenty years!" January 19th, 1893. I have received your two letters asking for Cattleya Lawrenceana, Pancratium Guianense, and Catasetum pileatum. Kindly excuse my answering your letters only to-day.
The construction of the flower in another closely allied orchid, namely, the Catasetum, is widely different, though serving the same end; and is equally curious. Bees visit these flowers, like those of the Coryanthes, in order to gnaw the labellum; in doing this they inevitably touch a long, tapering, sensitive projection, or, as I have called it, the antenna.
As soon as the three Orchidean forms, Monachanthus, Myanthus, and Catasetum, which had previously been ranked as three distinct genera, were known to be sometimes produced on the same plant, they were immediately considered as varieties; and now I have been able to show that they are the male, female, and hermaphrodite forms of the same species.
This Catasetum, wafted by the wind, when the seed was sown, found conditions suitable where it lighted, and quickened, whilst all its fellows, carefully provided for, died without a sign. It thrives upon the moisture of the house. In a very few years it will flower.
We also found on our last visit something new a very large bulbed Oncidium, or may be Catasetum, on the top of Roraima, where we spent a night, but got only two specimens, one of which got lost, and the other one I left in the hands of Mr. Rodway, but so we tried our best.
