unrecognizing

Tall fair men were beginning to complain of her unrecognizing manner.

How could these blank, unrecognizing eyes be Hugh's eyes, which had never until now met hers without love?

Their blank, unrecognizing expression, as they rested on him in mere kindliness, made her lovely eyes awful to him as a Gorgon's.

They seemed something alien in that moment; and they, gazing upon her white face and unrecognizing eyes, spoke in awed whispers.

The sight of his blank, unrecognizing gaze brought him back to the consciousness of the utter change in himself.
