Well it looks like you have 2 types one looks like a Dendrobium cane in the lower picture , is it attached to the rest of the plant , maybe the old canes have been cut off ? I would clean it up and pot in an orchid bark mix , if it is a Dendrobium they like to drink and dry , I would not divide it right now , that can be done later when the new growth matures . Also reduce light on it until established not total shade but not hot sun . Hope this helps a little . Gin
