Lórinand

The precise point where the name Lórinand fell out of use is unclear. Our last definite use of the term is in the middle of the Second Age, after the fall of Eregion and the founding of Imladris in II 1697. It may have continued in use for some time after this, perhaps even until the settlement of Galadriel in the land after III 1980 (that is, nearly four thousand years later).

Several of the older terms for Lórien translate as names like 'Valley of Gold' or 'Golden Wood'. It would be natural to make a connection to the golden mallorn trees for which the land was famous, but this cannot be the case. The mellyrn were brought there by Galadriel, and would not have existed during the Second Age. It is therefore conceivable that the name Lórinand was not actually used at the time, but was applied retrospectively by those familiar with the golden trees of later years.
