That's half-correct. Var. itinerans is a runner, but there are varieties that are not (var. guangdongensis, var. chinensis, and var. lechangensis).

Hard to tell from that picture if it is indeed a runner. That coloration just looks a lot like M. sikkimensis. I suppose it's possible that there are more itinerans varieties around though. Dr. Hugo Volkaert told me that he could show me 20 different varieties in Thailand alone!
