yes each person can only get one of each . If you get two you can't place both on the alter . So pick up just one botanical and one crystal. Each set unlocks a chest that each member of the group can loot . so two bonus chests if done right .
So if Im getting it right than one person can loot one crystal + one flower? And then all 6 items has to be placed in the final room to open final chest?
I just finished a run where I picked up two crystals and a flower. I was able to place both crystals on their altar, I just had to back away a bit and aim at one side of the altar.
The last flower is right near the boss that drops a flower. When you go back up out of his area look on your right and there will be a lootable plant. Its all the way at the top of the ramp.
So as of 05/07/2013 I spent over one hour looking for the green crystal and could not find it. I found the blue thanks to this post. So I gave it a shot anyways and just the blue, red and yellow crystal spawned the chest and the other items spawned the 2nd chest. So it would appear that perhaps the green crystal could have been patched out? As others have mentioned I guess the big chest in the middle only is available via Dungeon Delves.
Duo'd with 19 rogue and 21 cleric; first boss was difficult, optional boss and final boss was a joke.
So there's nothing special if you get both chests? I just ran it with a 21 (now 22) Rogue + Dire Wolf companion...found out I was missing the Blue Crystal and went looking for it, and fell through the map being too nosey. If it's just a chest like the flowers, it's not worth running again anytime soon.

All die, so die well.
Blue crystal: First blue room, left side in the cluster of blue stones (after you get down the "stair")
Red crystal: on table at first boss, easy to find
first flower: on table at first boss, easy to find
Mushroom: dropped by second boss
Third flower: Over the second boss, right before going to next room (where it does the curved bridge) on the right side.
Could elaborate with a movie. but... too... lazy.
