I am pretty sure that D starts with Dor, both because of "land" and the presence of these letters in "broad". But I don't know what to do with the rest of it.
Btw, because I am in my gynecology rotation right now, every single freaking time I read that clue, my brain continues from the word "broad" to complete "broad ligament of the uterus".
At least in compensation I kept changing middle ear to Middle Earth all the time when doing ENT.
