Hey folks.
An interesting note about this species, from Taylor's book. There are four utric species that share a similar flower form (U. antennifera, dunlopii, capiliflora and dunstaniae, I think - excuse any spelling errors, I don't have the book handy.)
However; in two species the appendages extend from the upper corolla lobe, while in the other two, they extend from the lower corrola lobe. This indicated two completely different evolutionary paths to arrive at a very similar and seemingly very unlikely form. There must be a pollinator in the neighborhood with a very strong and particular attraction to that flower shape.
Anyway, just thought it was interesting.
