Alliances have
been proposed based in morphology and affinity to facilitate the
correct
identification of species.
Note:
Baptistonia species usually presents
cylindrical (cigar-like)
short or elongated pseudobulbs; semi-connate lateral sepals, except B.
colorata that has free
ones; long or short erect, arched or pendent inflorescences (paniculate
or raceme rachis).
The three
descriptions enhanced with lilac color represents species that have
front of anther cap with only a rostrum (without two lateral
appendixes).
Most of species in this
gallery have additional pictures showing vegetative aspects, flower
analysis and other topics about anatomy and morphology of flowers that
can be accessed on PHOTOSTUDY link.
