Walleechu Shortly after passing the first spring we came in sight of the famous tree, which the Indians reverence as a God itself, or as the altar of Walleechu. It is situated on a high part of the plain & hence is a landmark visible at a great distance. As soon as a tribe of Indians come in sight they offer their adorations by loud shouts. The tree itself is low & much branched & thorny, just above the root its apparent diameter is 3 feet. It stands by itself without any neighbour, & was indeed the first tree we met with; afterwards there were others of the same sort, but not common. Darwin 11 August 1833
