Flower heating following anthesis and the evolution of gall midge pollination in Schisandraceae [PDF]
, 2010 Premise of the study: Flower heating is known from a few species in 11 of the c. 450 families of flowering plants. Flowers in these families produce heat metabolically and are adapted to beetles or flies as pollinators.
