Q: About Utricularia subgenus Utricularia section Choristothecae

A: Having just dealt with section Chelidon, let us continue the freakshow with section Choristothecae! This section is probably most similar to Avesicaria, although the anthers, trap glands, and pollen set it apart.

Utricularia choristotheca
How do we start talking about this odd thing? The leaves are covered with long hairs. The rheophytic-style stolons are covered with gripping organs to hold onto rocks. The flower spur is inverted, so it sticks INTO the flower! And then there are the anthers; unique to the genus, they are on long stalks. Even the stigma is elongate. Very weird.

Utricularia determannii
Compared to its only companion in the section, this species is relatively subdued. It is only known from the type collection.
