The spectrum of the recently discovered cataclysmic variable star (CV)ASAS-SN 13cl shows that a secondary star with spectral type K4 (+- 2subclasses) contributes roughly half the optical light. The radial velocitiesof the secondary are modulated on an orbital period P_orb = 4.86 hr with avelocity semiamplitude K = 246 +- 9 km/s, and the light curve shows ellipsoidalvariations and an apparent grazing eclipse. At this orbital period, thesecondary stars in most CVs are substantially cooler, with spectral types nearM3. ASN-13cl therefore joins the small group of CVs with anomalously warmsecondary stars, which apparently form when the onset of mass transfer occursafter the secondary has undergone significant nuclear evolution.
