BOTA2000 Lecture Notes - Lecture 6: Eudicots, Caryophyllales, Proteaceae
Document Summary
Four stamens opposite sepals, filaments adnate to sepals. Pistil with long slender style, sometimes involved in secondary presentation. Pollination through wind, insects, birds or small mammals. Corolla of free, large, yellow or white petals, actinomorphic. Note 3-merous (e. g. monocots), 4-merous flowers (e. g. proteaceae) or flowers with many parts (e. g. nelumbonaceae) are more common in other flowering plants. Minor core eudicots contain phylogenetically basal groups (berberidopsidales,santales, caryophyllales) Hemiparasites able to produce sugars through photosynthesis but tap stems or roots of other plants for water & minerals. Seeds without testa (many bird pollinated & bird dispersed - sticky seeds) Large (33 families, 692 genera, 11 155 species) group (6% of eudicots) Herbs with swollen nodes, succulents, carnivorous plants (lecture 2 today) Many produce betalains (e. g. beta) instead of anthocyanin pigments. Small family of carnivorous plants 3 genera. Drosera - large genus (194 species 110 in south-west australia) lures, captures and digests insects using mucilaginous glands covering leaf surface.
