One of the soft maples.

From 1843–2018, two large beautiful mature trees grew in 🇮🇪 Ireland, on the grounds of ⟰ Trinity College in Dublin, [2] just outside the building holding the Book of Kells.  Said to have been planted there in a wet area of the grounds due to the tree's ability to draw from the soil and evaporate large quantities of water. [3]   A process, I learned much later, called phytohydraulics, using evapotranspiration.  Terminology!   Unfortunately, after 175 years of faithful service, and suffering from heart rot, the trees blew down/were cut down.
