Flora Pittsburghensis

Pyrolaceae

Wintergreen Family

Current botanists place this entire family as the subfamily Pyroloideae in the family Ericaceae, the Heath Family.

Pyrola elliptica

Pyrola rotundifolia

Indian Pipes (Monotropa uniflora). Indian Pipes are strange little plants that have no chlorophyll. They get their food by theft: they steal it from little fungi in a process called myco-heterotrophy. Since they have no chlorophyll, they have no particular need for light; and they are often found deep in the woods. They bloom in late July. As they age (which happens very quickly), the dangling bells of these peculiar plants turn more and more upward; eventually, when they go to seed, they will be completely vertical, and completely black. —Note that Monotropa is placed in the family Ericaceae by current botanists; we list it both there and here, because the Check List of the Vascular Flora of Allegheny County places it here.
