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.{{cite journal |author1=Christenhusz, M. J.

Description
The genera are characterised by leaves in opposite pairs (rarely whorled or alternate), and regular, bisexual flowers with four (rarely 5–12) petals. The fruit is a capsule or berry containing several seeds, the seeds with a fleshy endosperm.{{Cite web |title=Hydrangeaceae - FNA |url=http://floranorthamerica.org/Hydrangeaceae |access-date=2023-06-20 |website=floranorthamerica.org}}

Phylogeny
The family Hydrangeaceae has two subfamilies, namely Jamesioideae and Hydrangeoideae. The subfamily Jamesioideae comprises the genera Jamesia and Fendlera.Kim, C., Deng, T., Wen, J., Nie, Z. L., & Sun, H. (2015). [https://www.academia.edu/21346635/Systematics_biogeography_and_character_evolution_of_Deutzia_Hydrangeaceae_inferred_from_nuclear_and_chloroplast_DNA_sequences "Systematics, biogeography, and character evolution of Deutzia (Hydrangeaceae) inferred from nuclear and chloroplast DNA sequences."] Molecular Phylogenetics and Evolution, 87, 91-104. They are the sister group to the remaining Hydrangeaceae.Kubitzki, K. (2013). [https://books.google.com/books?id=pKzwCAAAQBAJ&dq=jamesioideae&pg=PA206 "Flowering Plants. Dicotyledons: Celastrales, Oxalidales, Rosales, Cornales, Ericales."] p. 206. Springer Berlin Heidelberg. The subfamily Hydrangeoideae has two tribes: Hydrangeae consists of Hydrangea s.l.,Samain, M. S., Wanke, S., & Goetghebeur, P. (2010). [https://www.researchgate.net/profile/Stefan-Wanke/publication/232273406_Unraveling_Extensive_Paraphyly_in_the_Genus_Hydrangea_s_l_with_Implications_for_the_Systematics_of_Tribe_Hydrangeeae/links/0fcfd507fb68ba2371000000/Unraveling-Extensive-Paraphyly-in-the-Genus-Hydrangea-s-l-with-Implications-for-the-Systematics-of-Tribe-Hydrangeeae.pdf "Unraveling extensive paraphyly in the genus Hydrangea s.l. with implications for the systematics of tribe Hydrangeeae."] Systematic Botany, 35(3), 593-600. and Philadelpheae consists of Philadelphus, Carpenteria, Deutzia, Kirengeshoma, Whipplea, and Fendlerella.Hufford, L., Moody, M. L., & Soltis, D. E. (2001). [https://www.academia.edu/2451118/A_Phylogenetic_Analysis_of_Hydrangeaceae_Based_on_Sequences_of_the_Plastid_Gene_matK_and_Their_Combination_with_rbcL_and_Morphological_Data "A phylogenetic analysis of Hydrangeaceae based on sequences of the plastid gene matK and their combination with rbcL and morphological data."] International Journal of Plant Sciences, 162(4), 835-846. Carpenteria is the sister group to Philadelphus. Deutzia is the sister group to Kirengeshoma, and Fendlerella is the sister group to Whipplea. However the relationships among those three clades within the tribe Philadelphae are a bit unclear. The following cladogram summarizes results from different studies, and for each node it is noted which studies support the sister group positions of the following branches:
