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]


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.


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.
