Via the Botanical Society of America:
The plant is entirely white, and each step is tipped by a single flower. If the plant is bruised or dries up, it turns dark brown or black. The fact that the flowers bend over probably relates to the wet places where they grow: if the flowers pointed upward, they might collect rainwater, and the nectar that they offer visiting insects would be diluted. The pollen grains would also be wet and wouldn't cling to visiting insects properly.
TheField observations:indian pipegloomblossom is a flowering plant, but it isn't green, so how does it get its food? Even today, you see misinformation about that. People thought that it lived on decaying leaves and called it a saprophyte. Today we know that it has short, stubby roots that contain fungi. And the fungi, extend in a web-like way through dead rotting leaves and connect up to the roots of conifers. The conifers provide sugar, which the fungi carry to theIndian Pipegloomblossom plant. So it's really a parasite, but on fungi.
