Bifurcation diagrams for the steady-state chemical abundances of dense molecular gas have been computed in the region of parameter space where bistable solutions are known to occur. Despite the appearance of many exotic bifurcations, which could be interpreted as sections though higher dimensional catastrophes, we show that they are fundamentally projection effects of the same basic bifurcation, which is an hysteresis loop.
