Identification spectra (in f_λ) of 12 of the new HST‐discovered high‐redshift SNe Ia, shown in the rest frame. Classification features are analyzed in § 2.3. The data are compared to nearby SN Ia spectra of the same age as determined by the light curves (see Table 3). Classification of the five SNe without spectra (SN 2003XX, ﹩z=0.94﹩; SN 2002fx, ﹩z=1.40﹩; SN 2002hp, ﹩z=1.31﹩; SN 2003ak, ﹩z=1.55﹩; and SN 2003aj, ﹩z=1.31﹩) are discussed in §§ 2.3 and 3.1.
