31) Violaceae • Violet Family • Herbs (tropical members are trees and shrubs) • Leaves alternate, sometimes basal or on very short rhizomes, triangular in shape, stipules present • Flowers perfect (stamens and pistil present), zygomorphic, 5-merous, petals 5, sometimes the abaxial petal spurred • Stamens 5, with anthers touching in a ring around the pistil; 2 abaxial (or all) anthers with glandlike or spurlike nectaries • Fruit a capsule
ExamplesViolaceae • Viola (violet, pansy, johnny-jump-ups)
Viola X wittrockiana Pansy
32) Salicaceae • Willow Family • Deciduous trees and shrubs, leaves simple, often serrate or dentate, the teeth salicoid (vein expanding at the tooth apex and associated with spherical, glandular setae); • Plants dioecious ( “two houses” - flowers imperfect – staminate and pistillate on different plants) • Often catkin bearing; flowers seemingly subtended by bracts with a cup-like disc or gland • Seeds with an aril or tufts of hairs
ExamplesSalicaceae • Salix • Salix babylonica (weeping willow) • Populus • Populus tremuloides (quaking aspen) • Populus alba (silver poplar) • Populus deltoidea (cottonwood)
Salix spp. Pistillate catkins
Populus tremuloides trembling aspen
Populus alba Staminate catkins
33) Fabaceae (Leguminosae) • Legume or Bean Family • Herbs, shrubs, trees, vines or lianas; with high nitrogen metabolism and unusual amino acids, often with root nodules • Leaves pinnately or palmately compound or sometimes simple; pulvinus usually well developed, showing sleep movements; stipules usually evident. • Flowers often papilionaceous and distinctly zygomorphic • Corolla of subfamily Faboideae of 5 petals forming a banner, 2 wings, and a keel (2 petals fused along one edge); stamens 10 (all free, 9 fused and 1 free, or all 10 fused) • Carpel 1, with short gynophore (stalk below the ovary); Fruit usually a legume
ExamplesFabaceae – Subfamily Faboideae • Pisum (pea) • Faba (bean) • Lupinus (lupine) • Glycine max (soybean) • Medicago sativa (alfalfa) • Trifolium (clover) • Lens culinaris (lentil) • Arachis hypogaea (peanut)
