Identification of a gentian

Hi!

I need help to identify this gentian. The best suggestion so far is G. algida var/ssp purdomii.

cheers

Gentiana algida is said at Flora of China to have terminal cymes (whereas your plant has axillary and terminal cymes), "flowers solitary, rarely in terminal 2 or 3(-8)-flowered cymes", with blue-striped flowers, sometimes with blue spots in the floral tube.      http://www.efloras.org/florataxon.aspx?flora_id=2&taxon_id=200017879

The habit of your plant, with axillary and terminal cymes, plus green spots in the floral tube makes me wonder if it is Glentiana straminea:

Here's an illustration of G. straminea that shows a similar habit to your plant:
