Inziladun spoke: [
I don't recall seeing the argument that Nimloth was a cherry tree. What was the basis for that?]
I think they are referring to the blossoms of Nimloth as appearing to look like cherry blossoms. As a descendant of one of the two trees, where in various texts it is both described with blossoms like a cheery and leaves like a cherry tree. Nimloth is not described as such though in any text, but it did seem to glow? at times in at least one text form:
HOME Peoples of Middle Earh; The History of the Akallabeth referred to as the
night-shadows departing
when in flower.
Earendil in some early versions of the
Earendillinwe (as it eventually came to be so-named in
Lord of the Rings See
HOME Treason of Isengard) for the name), also carries cherry blossoms on his ship when he sailed to Aman, most likely in reverence to the Two Trees--
he needed all the help he could get.
The final long-misplaced and later rediscovered version for
Earendillinwe scheduled for inclusion in the book was published in
Lord of the Rings: A Reader's Companion. Mr Tolkien couldn't locate the final form and used an earlier form of the poem. Just an mildly related aside here on this last point, and probably the only really new point of interest.
