 Viola labradorica 'purpurea' = V. riviniana? (what's the story)
The 'purpurea' suffix to the Viola labradorica name was used to indicate a form with more-purple leaves, but the plant encompasses a range of leaf-purplenesses, so such a qualification may not be very useful.
Viola labradorica is a valid species, as you describe, but I have yet to see it in cultivation.
Footnote: Viola riviniana Purpurea Group seems to be gaining adoption, but I am not 100% sure it is the best name, since there is also a Viola purpurea, and the ICNCP frowns upon a cultivar group having the same name as a species in the same denomination group.

 Mycorrhizal Citations
Size and nutrient concentration of the patches were varied between treatments.4 Species differed in the size of their root systems and in their ability to respond to localized nutrient-rich patches.
Oxalis acetosella and Viola riviniana, which produced the smallest root systems, showed similar root growth in nutrient-rich and control patches.
Only one species (Oxalis acetosella) could be shown to benefit from colonization by increased phosphate uptake.7 The soil is a heterogeneous environment in terms of nutrient availability; differences between species in the ability to exploit this heterogeneity may affect their distribution, and could be a mechanism that reduces interspecific root competition.
