SUBGENUS Dracontia Luer 1986

Characterized by the caespitose habit and a ramicaul as long or longer than the leaf and an inflorescence that arises from the ramicaul through a spathe with or without a distinct annulus a short distance below the abscission layer. The spathe subtending the inflorescence is large conspicuous and foliaceous in 3 species. The relatively large flowers are bourne successively or simultaneously in loose, racememes with flowers that have tailess sepals but some speceies have a dorsal sepal with narrowly acute apices. The lateral sepals are connate from midway to deeply connate into a synsepal that is shortly bifid at the apex. The column is relatively short and often thickened towards the base and the well developed foot has a more or less free tip that is sometimes curved and reminiscent of the free-incurved extension of the column foot seen in Masdevallia. The anther is subapical or ventral with a pair of free, ovoid pollina other than in P macrantha that has a conspicuously elongated anther cap and the stigma is ventral in all spcies of the section.
