The Ferocious Man-eating Tree of Madagascar

It is from seven to ten feet high and something like a grape fruit in shape, with rough, ugly tendrils stretching out in all directions. The trunk is black and hard as stone.

At the top of. the tree are six palpi, six feet high, that rear straight up and twine and whirl about incessantly. There is a cup also at the top which contains a clear, appetizing looking fluid. But alas for him who drinks it. He becomes peculiarly crazed and unable to get down.

Then it is that the whirling palpi twine themselves slowly but surely about the helpless man until all life is gone. This species of tree is naturally avoided as a deadly serpent would be, and the natives consider that it is actually alive and possessed of an evil and terrible spirit.

Valley of the Zombies, 1946

Ormand Murks, thought dead but survives via means of a voodoo potion, has an insatiable need for blood. Murks kills Dr. Maynard, the doctor responsible for  committing him to an insane asylum. Meanwhile two young lovers are suspected of the murders and are out to prove their innocence. Though this doesn’t have much in the way of valleys or zombies, it is a fun little flick with pretty good acting and dialog.
