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
Fagaceae
Fagaceae
Quercus fruits = nuts = acorns
Quercus leaf
Quercus gambelii – Gambel Oak
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
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.
Brassica nigra
Cakile maritima
Cardamine
californicum
Raphanus sativus
Thysanocarpus
laciniatus
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.

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)
Aceraceae
Aceraceae insect and wind
pollinated
Acer negundo – Box elder
Acer glabrum – Mountain Maple
Acer saccharum
• http://www.youtube.com/watch?v=PMLcjYzENU&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
