Physical constraints on temperature difference in some thermogenic aroid inflorescences.

abstract：BACKGROUND AND AIMS:Reciprocal herkogamy, including enantiostyly and heterostyly, involves reciprocity in the relative positions of the sexual elements within the flower. Such systems result in morphologically and, since pollen is deposited on and captured from different parts of the pollinator, functionally distinct f...
