Habit of a Hydrangea macrophylla

Hydrangeaceae is a family of flowering plants in the order Cornales, with a wide distribution in Asia and North America, and locally in southeastern Europe. it comprises nine (or fewer) genera with 223 known species.[3]

Overview

In its broad sense (as treated by the Angiosperm Phylogeny Group), the family includes 17 genera, but some botanists divide the family into two, with seven genera split off into a separate family, Philadelphaceae. The genera of Hydrangeaceae were formerly included in a much broader (but polyphyletic) Saxifragaceae.

The genera are characterised by leaves in opposite pairs (rarely whorled or alternate), and regular, bisexual flowers with 4 (rarely 5–12) petals. The fruit is a capsule or berry containing several seeds, the seeds with a fleshy endosperm.

Genera

Subfamily Hydrangeoideae
Subfamily Jamesioideae

In addition, the genus Pottingeria is sometimes included in Hydrangeaceae, while others treat it in either Celastraceae, or in its own family Pottingeriaceae.
