vintage Pyrex casserole, mystery pattern, green starflower & grasses spray

We like this vintage Pyrex pattern, and very seldom find it! At first glance it looks like the popular green and white Glasbake pattern - though it's not really much like it except for the colors, and the 70s wildflower style.

The dish is a 1 1/2 quart size, about 10" across the handles. Both the dish and the lid are marked, and both pieces are in very good condition, no chips, very little wear or scratching.
