Flowers 
Morphology, Evolutionary Diversification and Implications for the Environment

In this book, the authors present topical research in the study of the morphology, evolutionary diversification and implications for the environments of flowers. Topics discussed in this compilation include the bioactive components from asteraceae flowers; the classification, phylogenetic status and uses as ornamental groundcover of the arachis species; understanding the role of pigments in flowers; flowers as sources of therapeutic molecules; the floral development of sauvagesia (ochnaceae) revealing different origins of presumed staminodes; pollen grain diameter, in vitro pollen germination and regression between grain diameter and in vitro pollen germination in pickerelweed (pontederia cordata L.) and the development of novel pollination techniques to overcome the effects of heteromorphic incompatibility and herkogamy in pickerelweed.
