The Magnoliidae
Family Overview - The Magnoliales
Magnoliaceae - the Magnolia Family
Diversity:  12 genera and about 230 species, mostly trees/shrubs

Distribution:  Temperate northern hemisphere with high Asian diversity - 2 genera with 4 species in Texas.

Floral structure:


Calyx/Corolla not differentiated

Significant features:  leaves are simple, alternate, and stipulate with the stipules fugacious (falling early) and leaving a stipule scar that circles the shoot at the node (distinctive vegetative feature of the family). Flowers shoot-like, i.e., with numerous, separate parts on an elongate receptacle.

Magnolia grandiflora - with apocarpous gynoecium maturing to form an aggregate of follicles - mature ovules (seeds) offered to dispersers by hanging on a thin funiculus
