We consider aspects of the relationship between nilpotent orbits in a semisim-ple real Lie algebra g and those in
its complexification gïÂÂ. In particular, we prove that two distinct real nilpotent orbits lying in the same complex orbit are
incomparable in the closure order. Secondly, we characterize those g having non-empty intersections with all nilpotent
orbits in gïÂÂ. Finally, for g quasi-split, we characterize those complex nilpotent orbits containing real ones.
