The calyx is tubular, terminated by two lateral lobes.  The corolla is two-lipped.  The lower lip terminates in three lobes.  The distal portion of the upper lip forms a hood, called a galea, which encloses the stamens and style.  There is a slit in the bottom of this structure to provide access to pollinators.  A portion of the upper lip surrounding this slit has been removed in this specimen, to reveal the stamens and stigma.
