The most common wood used in paper making is the scrap from lumber production, and as to the species...whatever they harvest close to the paper mill is what they use. There are two broad categories of paper: groundwood and free sheet. Groundwood is the old-fashioned kind of paper, and there you really need softwood timber because they make it by soaking wood in water until the fibers come apart. Most groundwood ends up as cardboard. Free sheet is made by dissolving the fibers in chemicals. By the time the wood is sent into the sheet-forming process it's no longer wood but a kind of cellulosic glop, for lack of a better term. They're starting to really like poplar; it's as easy to work with as pine, and it grows so fast you can cut it for paper production in only seven years.
Generally speaking, softwoods are best for paper making as it's easier to split or break up the fibres in the pulping process. Softwood fibres tend to be more flexible than hardwood fibres which lends itself to making thin flexible sheets.
Examples of softwoods are Fir, Spruce, and Pine. a good site to visit is in related links below this answer.
