Stapelia gigantea - My father-in-law introduced me to this plant. I finally find one recently. He called it a "dead horse cactus". Other names I've hear it called are "toad cactus", "star cactus". The beautiful blossom smells really bad and has red veins running through it. Don't let the plant be splashed by cold rain. It will made it look like it has some kind of disease with large black spots. It just doesn't like cold water.
