Small Spreading Pogonia

A station in Barbour County, West Virginia, is 240 km north of other stations and may be a result of introduction (K. B. Gregg 1989).

Cleistes bifaria has been treated as a variety of the following species; it is readily separated by its relatively short column, which is correlated with the relatively small size of other floral parts, and differences in lip keel. It is, to a large extent, isolated from the following taxon by geographic distribution and flowering time where their distributions overlap (P. M. Catling and K. B. Gregg 1992).

Plants (12–)15–46(–64) cm (in flower). Leaves: blades on flowering stems, (2.5–)45–145 × (4–)6–25 mm. Flowers: sepals 24–55 × (2–)3–5 mm; petals 21–36 × 6–10(–12) mm; lip 21–33(–38) × 13–16 mm, central keel relatively thick, 2.4–2.6 mm wide, very slightly grooved, groove 0.3 mm deep and verrucose or braided with 5–7 discontinuous ridges; column 13–19 mm. Capsules (9–)27–41(–81) × (3.2–)4–8(–8.5) mm. 2n = 18.
