It is debatable whether the same word is used in the two attestations. The editor of S Modw tentatively interprets the term as a devoiced variant of boton, and defines it accordingly. The editor of bibb roth (G) points out that the term may be related to paucus, but that is not supported by the FEW. Only the word boton (also with the sense ‘petite excroissance d’où naissent les branches, feuilles, fruits ou fleurs d’un végétal’) is included in Möhren’s Le renforcement affectif de la negation (pp.66-74).
