Not sure what that is. Looks sort of like Japanese arrow boo, but I wouldn't sy for sure-doesn't look like anything we have here, but it definitely looks like arrow shafts. Where are you located? Cane/boo usually needs to dry a couple months before straightening. Any heat source will work as long as it's not so hot that it scorches it badly. Straighten each internodal section individually, then straighten the nodes to line them up. Cut your shafts a little bigger than you thingk you'll need as it will shrink some while drying.
