What is the difference between this and Stylidium graminifolium as this is what I thought it was and what has previously been identified on my block. Is it possible to have both?
Yes both may occur in the same area . A while ago Stylidium armeria subsp. armeria was included in a loosely broad taxonomic concept of S. graminifolium . I have added the relevant information to the species pages here in NatureMapr, hence see: • Stylidium armeria subsp. armeria • Stylidium graminifolium • and so on such as Stylidium montanum .
