Viola sagittata seed dispersal

I am looking for information on how Viola sagittata seeds are dispersed. 
The species is shade-intolerant and seems to be found most often in
low-nutrient soils where the soil has been scarified or compacted.  Ants
seem unlikely as a seed-dispersal vector for a species that appears to
depend on long-distance dispersal to small, ephemeral microhabitats, but I
know of no structures associated with violet seeds that would suggest
either a bird attractant or the ability to be carried a long distance by
wind.  Any data out there?  Please reply via e-mail.
