Omta Tso, Bhutan |
It was initially compared with Primula griffithii and P. tanneri but it was distinguished by leaves which are rounded at the apex, bluntly crenulate at the margin and a calyx which is sparsely farinose and glandular. The flowers are described as rich purple.

Color variations of P. calderiana X P. strumosa |
So are the plants at Omta Tso P. tsariensis or are they P. strumosa?
The most obvious differences between the two species are that P. calderiana / P. strumosa smells "disagreeable", and has farina present on the bud scales, and on the upper scape, calyx and pedicels whereas P. tsariensis is not noted for its smell, has efarinose bud scales and only trace amounts of farina on the pedicels and calyx.

I took the same flowers sometime in 2009 nearby Omta Tsho. I am sharing the link but sorry about the leaves.
