The flower of this species is especially large -- about 11 cm from the leaf axil to the end of the flower, and about 4 cm across.  The larger leaves in this image are from the Drymonia, the smaller leaves are from a nearby Aeschynanthus.  This species needs a lot of space.

D. conchocalyx is native to medium-high altitudes in Costa Rica and Panama, and requires moderate temperatures indoors.  There is quite a bit of variation in the species in calyx color and petiole length.  The calyx can be red, green, purple or white, and the petiole can be almost non-existent or up to 7 cm long.
