SUBGENUS Specklinia SECTION Muscosae Lindl. 1842
Characterized by the small caespitose to repent plants with a ramicaul that sometimes approaches the length of the leaf and blooms with two [rarely reduces to one] to more successively flowered, congested, subcongested or less common, lax, racemose inflorescence that may be shorter to longer than the leaf. The lateralspela may be free or connate and the petals are more or less acute to acuminate. The ligulate lip often ciliate also often has small marginal lobes near the middle. The disc had a pair of longitudinal calli that usually terminate in a more or less erect, bilobed projection above the base which is more or less accomodated by the concave column foot. The base of the lip is often membraneously bilobulate and the lip of several species approach that found within the genus Trichosalpinx.
