A word appearing as {alalbe >>} alalme “inflorescence” in notes from around 1959, derived from √GAL (PE17/153). Compare this to [ᴹQ./ᴱQ.] alalme “elm” from The Etymologies of the 1930s and the Qenya Lexicon of the 1910s (Ety/ÁLAM; QL/29); in the 1959 notes Tolkien decided “elm” was albe.
Neo-Quenya: In these 1959 notes, the root √GAL had a connection to flowers seen nowhere else; see alma “flower” for discussion. As such, I think this “inflorescence” word was a transient idea, and I would use other words like lós and olos “inflorescence” for purposes of Neo-Quenya.
alalmë (1) noun "inflorescence" (PE17:153), cf. alma #2.
