Such quasiparticles have been proposed in various contexts in condensed matter. Using first principles calculations, we identify a pair of semi-Dirac bands anti-crossing at \u22123\u2009eV below the Fermi level in the electronic structure of hexagonal close-packed cadmium. The linear out-of-plane dispersion is kept up to the Fermi level. We demonstrate that the dichotomy between the linear and quadratic dispersions is driven by an orientation-sensitive hybridization between the\n                    <jats:italic>s<\/jats:italic>\n                    and\n                    <jats:italic>\n                      p\n                      <jats:sub>z<\/jats:sub>\n                    <\/jats:italic>\n                    orbitals.
