Possibly OK. However, if it is S. sericea, we need to be absolutely sure because the record will be added to official records for rare species. If you have a collecting permit you should take a bit in to the herbarium or the desk at the botanic gardens. Otherwise you need to check whether the hairs on the plant are attached at one end or in the middle, and whether the stems are densely hairy or not. A good macro photo would help, or field notes.
