Rosids III Fagales Brassicaceae Rutaceae Anacardiaceae Aceraceae
Fagaceae • Oaks • Many tree species throughout N. America • TREES with SINGLE NUTS ATTACHED TO SPINY OR SCALY CAPS • One species in Colorado, Quercus gambelii
Brassicaceae (Cruciferae) — Mustard family • FOUR MEROUS (old name cruciferae, like a cross) • HERBS, rarely shrubs • Tetradynamous stamens = 4 stamen, 2 long, 2 short • Gynoecium with a superior, 2- carpellate/loculate ovary, with axile-parietal placentation and a usually 2-valved, dehiscent fruit with a replum (silique or silicle). • 365 genera / 3250 species
Brassicaceae Glucosinolates - major plant secondary products in the Brassicaceae and close relatives. - deter herbivory and parasitism - flavoring agents in the commercially important members of the Brassicaceae, such brocolli, cauliflower, and mustard.
Brassicaceae • Broccoli, brussels sprouts, cauliflower, cabbage, collards, kale (all cultivars of Brassica oleracea) • Rutabaga and canola oil (B. napus), mustard (B. nigra), turnip (B. rapa) • Arabidopsis thalliana is noted as a model for detailed molecular studies.
Malvaceae • The Mallow Family • Monadelphous stamen • Mucilaginous plants • Often with stellate trichomes
Malvaceae – Economic importance Gossypium spp. (cotton, the world’s most important fiber plant) and Ceiba pentandra (kapok), in both of which the seed trichomes are utilized, and Corchorus spp. (jute), a bast fiber plant and source of burlap; Theobroma cacao (cacao, the source of chocolate), Cola nitida (cola), Abelmoschus (okra), and Durio zibethinus (durian) Ochroma pyramidale (balsa) and Pachira aquatica; Brachychiton, Chorisia (floss-silk tree), Dombeya, Fremontodendron, Hibiscus (mallows), and Tilia (linden tree). Many others, such as Adansonia digitata (baobab, tropical Africa) are of great local economic or ecological importance.
Hibiscus sp. Kosteletskia virginica
Anacardiaceae • Cashew or sumac family • SHRUBS W/ 3-LOBED OR PINNATE LEAVES • 1-SEEDED RED OR WHITE BERRIES • Poison Ivy and Poison Oak are in this family • Important shrub ecologically, Rhus trilobata
Aceraceae • Maple Family • TREES WITH OPPOSITE LEAVES AND WINGED SEENDS IN PAIRS • Acer glabrum and Acer negundo (Box elder)
Acer saccharum • http://www.youtube.com/watch?v=PML-cjYzENU&feature=related • Maple syrup is the boiled down xylem (commonly called sap) that the tree is sending up from the roots to the leaves to get the leaves started in the spring • It’s about the only time the xylem is rich in sugars
