The Mesoamerican subtribe Thyrsantheminae includes just 21 species, but contains nearly the full range of morphological and ecological diversity in the family: from fully open to tubular flowers, cleistogamy to chasmogamy, spreading stoloniferous plants to compact rosettes, and from habitats at sea level to 3,000 m in elevation.
Effects of light and nutrient availability on chasmogamy and cleistogamy in an understory tropical herb, Calathea micans (Marantaceae).
Self-pollination can be favored by cleistogamy, chasmogamy and self-compatibility, while cross pollination can be favored by dichogamy, herkogamy and self-incompatibility (Frankel & Galun, 1977).
These mechanisms include protogyny, chasmogamy, heterostyly, self-incompatibility, self-sterility, entomophily, anemophily, and hydrophily.
