A noun appearing as ᴱQ. sirpe “stem, stalk (slender tube, etc.)” in the Qenya Lexicon of the 1910s under the early root ᴱ√SIRIP (QL/84).

Neo-Quenya: As this early root does not conflict with any later forms, I would retain this word as ᴺQ. sirpë “stalk, slender tube”. However, I adapt the early root as ᴺ√THIRIP “stalk” to preserve more Gnomish forms, so I would assume the s in ᴺQ. sirpë is from older þ. Furthermore, for “stem” I would use the later word Q. telco (LotR/1118).
