Unusual shape, but nice unusual! The eye is directed by the generous petals and dorsal all marked with sanguine dots arranged in graceful streams toward the delicate green veining overlaying a custard yellow staminode, interestingly framed by a halo of red bristles. The solid/uniform yellow pouch is like a deep relaxed breath after the visual roller coaster of the rest of the bloom. Wow!
When brachy x multi are good, they provide a visual feast! I love it.
