Can anyone identify...?

PVR'd this from TCM, an exquisite film. I've been poring over the cast listing, much of it uncredited, and I can't match a player to one of my favorite performances. She's that wonderfully droll old lady who lives with the other two sillier women, and sees the hysteria for what it is. Seems like that fine of a character actress must've been in lots of other stuff, but I can't seem to place her.
