No, we came down through Grand Bay instead of Mobile-a little shorter we found. Was going to drive up there but my mother and siblings complained as they're not to much into botany...but this coming summer I can legally drive myself. Now whether my parents will allow me to borrow the car and leave them on the island remains to be seen... I did look on Dauphin Island for another rare plant that grows on the big shell middens on the backside near the causeway-could not find it. Looked for an hour or two in the hot sun, then got home and had two botanists tell me they'ld seen it, "just last year, all over the place." At any rate, this little thing is interesting: common named buckthorn something, grows on shell middens up and down the Gulf Coast, and a few places inland on limerock outcrops. One of the few native plants I know of that is so closely linked with archeological sites-there are actually a couple others that are limited to shell middens.

I didn't know that. Why are they linked to archaeological sites? Were the plants used by the ancient inhabitants?
