There is no in game tree like that, to say 'this exists, but you haven't found a blah yet to make it from'

the list of what you do know is in the crafting stations... the cook pot, the forge, the workbench, and the hammer. If you want something and don't see it, try upgrading your stations, or making additional crafting support items like nails (always make one round of nails as soon as you get that nail type). If you see something on the vendor you don't know what its for, maybe buy one. And so on.

you can cheat in the stuff to unlock all the recipes on their stations if you wanted an in-game reference. Or join a server with established people and run around picking up and putting back the materials for a min. Or get someone to toss you a char who is naked but can make everything. Several ways to get there...
Im with you... there should be a help with all the items listed maybe, but there isnt at this time.
