The basal part of the labellum stands over the bucket, and is itself hollowed out into a sort of chamber with two lateral entrances; within this chamber there are curious fleshy ridges.

唇瓣的基部位于桶的上方， 它本身被挖空成一个有两个侧向入口的腔室；在这个房间里有奇怪的肉质脊。

Bees visit these flowers, like those of the Coryanthes, in order to gnaw the labellum; in doing this they inevitably touch a long, tapering, sensitive projection, or, as I have called it, the antenna.

蜜蜂访问这些花， 就像那些Coryanthes的花一样， 为了啃唇瓣；在这样做的过程中， 他们不可避免地会接触到一个细长的、敏感的突出物， 或者我称之为天线。
