Monotropa hypopithys vs Monotropa uniflora -- an observational study near the University of Michigan Biological Station.

Abstract

Although both M. hypopithys and M. uniflora have shared many similar physiological appearances and have an indirect parasitic relations with other photosynthetic plants, each species seems to prefer a different habitat. M. hypopithys seems to prefer to grow in a cooler, drier condition with humus soil. Whereas M. uniflora seems to prefer to grow in a warmer, more moist with nutrient-poor soil.
