Specklinia subgen. Hymenanthae (Clade C) is a highly supported clade that includes the species of the Specklinia grobyi-picta complex. Species belonging to this clade can be recognized as species of Specklinia , as defined here, by their convergent lateral sepals, the obtuse petals, ligulate lip and pollinaria without caudicles or viscidium, and within Specklinia by the inflorescence that is frequently elongate, exceeding the leaves, racemose, multi-flowered, with several flowers open at once, the flowers mostly monochrome purple, yellow, green or whitish, never orange, a column with a pair of prominent, rounded wings near the apex and a pair or orbicular glands at the base, and a linearligulate lip. This subgenus of 37 species has the widest distribution in the genus. It is the only clade of Specklinia found in all areas from Mexico, through Central America and the Antilles, south to Bolivia and Brazil. The most variable and widespread of all species of the genus, S. grobyi , belongs to this group. All species of Specklinia from Brazil, as well as most species of Specklinia from the Antilles, Ecuador and Mexico belong to this subgenus.
