Particularly, special attention should be paid to Jeju, as a large part of the orchids that exhibit low levels of genetic diversity occur on this island (Cephalanthera subaphylla, Goodyera repens, Liparis pterosepala, Oreorchis coreana, Pelatantheria scolopendrifolius, Peristylus densus, Platanthera hologlottis, Pogonia minor, and Tipularia japonica).

Meanwhile, periodic and unpredictable dormancy makes small whorled pogonia one of the most elusive orchids in North America.
Since swamp pink and small whorled pogonia both tend to occupy relatively small spatial areas, land managers cannot readily determine their distribution across the installation by looking at aerial photographs or topographic maps.
Small whorled pogonia generally can be found rising from the leaf litter to a maximum height of around 10 inches, with five to six leaves that are "whorled" or encircle the top of the stem, just below the flower.
Large whorled pogonia also possesses the same number of leaves, in an identical pattern.
What is more, although the small whorled pogonia
is currently classified as a threatened species, it is not rigorously protected because it is a plant.

However elusive, the small whorled pogonia
is making a comeback.
