Salicaceae |
- Simple, alternate and stipulate leaves - Dioecious, imperfect flowers, perianth is absent, inflorescence a catkin, many ovules - 2 to 4-valved capsule, seeds attached to fine hairs, wind dispersed |
|
|
|
Betulaceae |
- Leaves alternate, spiral, simple and stipulate with pinnate venation - Inflorescence often a pendulous catkin, unisexual (imperfect) flowers and monoecious - Fruit: a 1-seeded nut or nutlet, animal or wind dispersed - Bark: sometimes exfoliates in layers, often horizontal lenticels (pockets for air exchange) |
|
|
|
Fagaceae |
- Usually alternate and spirally arranged along the branch, simple and often lobed, pinnate venation - Usually monoecious trees, inflorescence unisexual, male flower usually in a dangling catkin and female flowers in a head-like structure - Fruit in a nut, often covered in an involucre of scales (cap), acorn, animal dispersed |

Ulmaceae |
- Leaves alternate, simple and often very thick, with asymmetrical leaf bases (oblique) - Flowers solitary, or aggregated in cymes, 4-9 sepals, apetalous, 4-5 stamens, gynoecium superior - Winged samara, wind dispersed |

They requires wind/animal dispersion and need the acidity in animal's stomachs in order to breakdown the hard exterior (scarification) |

Hippocastanaceae |

The tissues of some species may be toxic. |
|
|
|
Aceraceae |

Samaras usually in pairs (the angle between the pair is diagnostic). Wind dispersed. - All species are woody, therefore shrubs or trees |
|
|
|
Oleaceae |
- Opposite, simple or pinnately compound - Dioecious or monoecious - Capsules, drupes, berries, or samaras. Wind dispersed. |
