Identification of a gentian


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

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.

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:

Calgary, Alberta, Canada - Zone 3
-30 C to +30 C (rarely!); elevation ~1130m; annual precipitation ~40 cm
