N/C versus N/O for the components of LZ Cep (red squares). The inset zooms on the primary value. The evolutionary tracks are from Meynet & Maeder (2003). The dotted line (resp. dashed, dot-dashed, short-dash long-dashed lines) are tracks for a 15 M (resp. 20, 25, 40 M) star. The bold lines indicate the Wolf-Rayet phase of the evolution according to Meynet & Maeder (2003), i.e. X(H) < 0.4 and Teff  >  10 000 K.
