In this brief note we point out that the four spatially resolved relativisticjets among the 14 dynamically confirmed black hole X-ray novae are all insystems with long orbital periods. Many shorter period systems show transientradio outbursts which are attributed to jets, but these jets have not beenspatially resolved. Super-Eddington accretion has been suggested as arequirement for jet formation and may be consistent with our compilation ofluminosities, but some super-Eddington outbursts did not form spatiallyresolved jets. We speculate that some as yet unknown process (or combination ofprocesses) favors formation of substantially larger jets in long periodsystems. Two short period systems show evidence for extent, but have not beenresolved into multiple components as the long period systems have.Comment: 19 pages, accepted to ApJ 07 March, spectral types added to tabl
