NICKOL, MARTIN G. Botanisches Institut und Botanischer Garten, Christian-Albrechts-Universitaet, Kiel, D-24098, Germany. - Flower morphology and floral ecology of Plumbaginaceae.
Within Plumbaginaceae adaptations to maritime habitats led to
significant morphological and physiological features. Focussing on the
characters of the bisexual flowers their morphological features and
distinctive change during anthesis can also be interpreted as
adaptations to the microclimatic conditions and the pollinator
abundance in the mainly coastal environment of the different species.
Even within the genera Armeria and Limonium
(Armerioideae) a great variety in special floral features influencing
pollination efficiency has developed, e.g. heterostyly and polymorphic
pollen grains. These morphological patterns can not be interpreted
solely as autapomorphic characters strongly influenced by actual
environmental conditions, but moreover including the phylogenetic
relationships of and within genera.
Key words: Armeria, floral ecology, flower morphology, Limonium, Plumbaginaceae
