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.

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. Brassicaceae

Brassica nigra

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.

Acer negundo – Box elder

Acer glabrum – Mountain Maple

Acer saccharum cjYzENU&feature=relatedhttp:// 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
