This is a creeping blackberry. I have looked in several books to try to determine the exact one. it might be pubescens or parvifloris, or perhaps hispida

On another forum I posed this berry and the responce was "dewberry" (no latin). What do you think of that?
I appreciate you time on this. The past week has seen me stumped by three new plants! Two down and this ...maybe number three is in the bag!

Dewberry is the common name of one of the Rubus spp that grows in Arkansas. It ripens two to three weeks before standing blackberries and in my opinion is somewhat sweeter. It bears with less frequency than the uprights though.

"Dewberry" is a general name for many species of Rubus, generally those with very few drupelets per fruit. The USDA PLANTS Database (plants.usda.gov) lists "dewberry" as a common name for 91 (!) species. The genus as a whole contains 2 or 3 times that many species in the US. So "dewberry" isn't a particularly helpful name and I'm a bit skeptical of the odds of nailing this guy down to a given species from an image.
