In addition, other six species (Bletilla striata, Galearis cyclochila, Neottianthe cucullata, Pelatantheria scolopendrifolius, Platanthera hologlottis, and
Pogonia minor, Table 1) also harbor extremely low levels of within-population genetic variation.
While swamp pink grows in forested, low nutrient swamps that are typically small in size and widely scattered across most of the installation, small whorled
pogonia can be found in a variety of habitat types across its natural range.
Large whorled
pogonia (Isotria verticillata)--a separate, but closely related species that in many ways mimics the small whorled variety--can be found in modest numbers throughout the state.
I knew from field conversations with local botanists and government officials that the small whorled
pogonia survived in scattered pockets of Virginia, but was rather scarce in the northern regions where I predominantly worked.
Daily spawning fraction estimated for this species was similar to that reported for
Pogonias cromis from the Gulf of Mexico (Fitzhugh et al., 1993), but higher than those estimated for other sciaenids, such as Seriphus politus (DeMartini and Fountain, 1981), Genyonemus lineatus (Love et al., 1984), Cynoscion nebulosus (Brown-Peterson et al., 1988) and Cynoscion guatucupa (Macchi, 1998).
Few people ever get a glimpse of Isotria medeoloides, more commonly known as the small whorled
pogonia, because of its erratic growing patterns.
The floral biology of Arethusa bulbosa, Calopogon tuberosus, and
Pogonia ophioglossoides (Orchidaceae).
These include rose
pogonia and grass pink, both of which produce delicate blossoms.
Nicknamed the "rarest orchid east of the Mississippi," the federally threatened small whorled
pogonia is dependent on fungi that form a bond primarily with oaks, hickories and American beech.
Likewise, the presence of
Pogonia species such as P japonica and P minor in eastern Asia as well as P ophioglossoides in eastern North America helps to paint a picture of what must have been a continuous flora between these two continents at a time prior to Pleistocene glaciation events.
Consequently, many orchids, such as grass pink, rose
pogonia, and white fringed orchid are found most often in coastal dune sands and in bogs and fens (a type of marsh).

Commonly known as rose
pogonia,
Pogonia ophioglossoides (Jussineu) is a native wild orchid frequently found in acidic, boggy areas.
Quantico also provides habitat for such federally-listed threatened or endangered species such as the bald eagle (Haliaeetus leucocephalus), dwarf wedge mussel (Alasmidonta heterodon), and small whorled
pogonia (Isotria medeoloides), an orchid.
