So just in case anyone has a need for this in the future, here's what you can get from the gathering points unlocked by using the favors for each region:

Botany
Churning Mists - Wyvern Wart / Dragon's Wart
Coerthas Western Highlands - Foxglove / Bitter Foxglove
Sea of Clouds - Void Nut / Heavensnut
Dravanian Hinterlands - Black Swan Feather / Mute Swan Feather
Dravanian Forelands - Bladeleaf / Swordleaf

Mining
Coerthas Western Highlands - Red Ooid / Red Roundstone
Sea of Clouds - Violet Ooid / Violet Roundstone
Dravanian Forelands - Green Ooid / Green Roundstone
Churning Mists - Yellow Ooid / Yellow Roundstone
Dravanian Hinterlands - Blue Ooid / Blue Roundstone

To make these nodes potentially spawn you have to fully deplete a level 60 node in these regions, so gathering from four to leave only one gather on each before using your favors is a good way to speed up the start of your favor timer.

For what these get used for, here's a link to the two-star turn ins i posted: http://theexodus.guildwork.com/forum/threads/5678bdd8002aa80b6a53a65d-two-star-crafting-turn-ins
