wiktionary
From early modern German Larche, Lärche, from Middle High German larche, from Old High German larihha, early borrowing from Latin larix, itself possibly of Gaulish origin. In the first century AD, Vitruvius wrote that the tree was given the Latin name "larigna" when the Romans discovered it at the town of Larignum.
etymonline
larch (n.)
type of coniferous tree with needle-shaped deciduous leaves, 1548, (William Turner, "Names of Herbes"), from German Lärche, from Middle High German larche, from Old High German *larihha, from Latin larix (genitive laricis), probably a loan-word from an Alpine Gaulish language. De Vaan discourages the suggestion that it could be related to Old Celtic *darik- "oak."
Native to the Alps; the name later was extended to North American species. Compare Danish lærke, Dutch lorken, also from Latin. In French, Old French larice was replaced by mélèze (14c.), a word of uncertain origin.
