“In southern Florida the orchid flora is more or less confined to the peculiar hammock formations in the Everglades and in the pine woods. In these the species are found on the trees and on the ground, not infrequently around or withing the openings of lime-sinks. Each hammock is apt to have a distinctive flora, and when an orchid is common in one hammock, it may be rare in, or absent from, the next.”
