Melissa I think I found the term you were looking for that started omb…. It is most likely obturator [ plant anatomy term ]?
Defined as 1) an outgrowth of the funicle, that forms a bridge between the micropyle and other tissues. 2)Part of the ovary of a flower that chemically guides the pollen tube to the micropyle.

Thanks, Harold. I love the term–do you know that humans have obturator muscles? The internal and external obturators originate deep in the pelvis, near the sitz bones, and end in the mass of muscles terminating on the trochanter (top of the femur). There is also an obturator nerve, and a hole in the pelvis itself is called the obturator foramen. The definition of the Latin word is something that occludes or blocks up an opening.
