V1310 Scorpii (Nova Scorpii 2010, No. 1) was an Fe II-type nova whose early spectral properties are broadly representative of the class. We present a 0.8-5.2 μm spectrum from 11 days after peak brightness that exhibit these properties. In addition to the emission lines of C I, N I, and O I, V1310 Sco also shows the well-known one and two micron Fe II lines as well as midwave infrared (MWIR) Fe II lines not previously reported in novae. The strongest of the MWIR Fe II lines all descend from the same term (c4P), a term that is different from those that produce the one and two micron Fe II features.
