First, I corrected the spelling of dysentrica to dysenterica. But the genus name keeps getting corrected to Pulicaria. Did you mean Pulicaria dysenterica? Pulicaria dysenterica is described as a downy plant. Wildflower Fleabane, Common Irish Wild Flora Wildflowers of Ireland Inula salicina has a synonym Inula glabra, which would indicate that it would be hairless. I don't know either of those plants.
