Unknown something from Mugecuo Lake, Sichuan - Veratrilla?

[arisaema]

I'm not even able to identify what family this one belongs to... It's in a 9cm pot, and the leaves are fairly thick and succulent. Anyone care to make a guess?

Gentianaceae?

[arisaema]

You know, it might be Veratrilla baillonii..? Gentianaceae didn't occur to me as the leaves feel wrong, they are crisper and more brittle than the big leaved, Chinese Gentiana and Swertia I'm familiar with.

I wondered about a rather vigorous nivalid primula but I can't feel the texture, (let alone the price  ) which might rule that out. Anyway, you'd know a primula.

[arisaema]

It has the feel of some thick-leaved Primula (think P. x pubescens or P. parryi without the stench), but I think the roots are wrong, and it didn't have an overwintering bud. (And I think the slope it grew on was too dry for most primulas to survive...)
