Word History

Etymology

borrowed from New Latin, genus name, from Greek hydr- hydr- + New Latin -angēa, feminine derivative from Greek angeîon "vessel, container" — more at angio-

Note: The genus name dates from linnaeus's Species plantarum, vol. 1 (1753), p. 397. Linnaeus took the name from Jan Frederik Gronovius and John Clayton's Flora Virginica, pars prima (Leiden, 1739), p. 50. Since the 19th century the name Hydrangea, taken to mean "water vessel," is said to refer to the "cup-like form of the seed-capsule" (hence Oxford English Dictionary, first edition, 1899). However, Gronovius, presumably the immediate author of the text, gives no indication of the name's significance. He describes the fruit of Hydrangea arborescens as "a small two-chambered vessel filled with tiny seeds, crowned with two small threads or little horns bent backward" ("… vasculo parvo bicapsulari seminibus minutissimis repleto, duobus parvis filamentis seu corniculis recurvis cornato"). This accords well with pictures of the plant's small seed capsules, though it takes some imagination to see an individual capsule as a water vessel.
