Crocus gargaricus ssp gargaricus and ssp herbertii are very similar, Mathew did not recognise ssp herbertii in his monograph. It is said that ssp herbertii increases by producing stolons and this is the principle distinction. An account of this plant and a photograph are to be found in the Quarterly Bulletin of the Alpine Garden Society Vol 68, No 2, pp205-206. There may be other factors to observe, presence/absence of leaves at flowering and the distribution in the wild might be relevant - Tony W has seen them in the wild and might be able to help. In my limited experience ssp gargaricus is easier to cultivate being more tolerant of the drier summers here, it sets a little seed for increase.

Just to be clear, the two subspecies are now recognised when Mathew did an update in The Plantsman June 2002.
