We calculate the upper critical induction $B_{c2}(\theta,\phi)$ of an orthorhombic ferromagnetic superconductor with parallel-spin \textit{p}-wave pairing along $\hat{\bm e}_3$ and an ellipsoidal Fermi surface with effective masses $m_1, m_2$, and $m_3$, where $\hat{\bm B}\cdot\hat{\bm e}_3=\cos\theta$. At fixed $\theta$, an ordinary $B_{c2}(\phi)$ is obtained, but at fixed $\phi$, a novel $B_{c2}(\theta)$ is predicted. For fixed $3View original: http://arxiv.org/abs/1210.7442
