The pollen-pouches approach slightly at the base, directly opposite the nectary, where the two viscid pollen-glands stand on guard. Now, were the opening of the necta- ry at this point unimpeded, the same condition would exist as in the i)ur- ple-fringed orchid — the tongue might be inserted between the pollen disks and withdrawn without touching them. But here comes the remarkable and very exceptional provision to make this contact a cer- tainty—a suggestive struc- tural feature of this flower, of which I am surprised to find no mention, either in our botanies or in the literature of cross-fertilization, so far as I am familiar with its bibliography. The nectary here, instead of being freely open, as in other orchids described, is abruptly closed at the central portion by a firm l^rotuberance or palate, which projects downward from the base of the stigma, and closely meets the lip below. 137.
