specimens report the flowers as totally white while others report the anthers as yellow. An interesting aspect of this variation concerns the possible transition of pollination systems in this species.

inhabits cloud forests mainly at middle elevation but spanning a broad range. An interesting hypothesis to test is if the more white flowers occur at higher elevations where the buzz pollinated species tend to decline. The species already presents the broad anther pores which in themselves hint to a transition that might be happening. One specimen from Cerro Hornito in western Panama (
<emphasis italics="true" pageId="149" pageNumber="150">Kriebel and Burke 5752</emphasis>
) might represent this species but the inflorescence is too immature to tell.
