Difficult to tell from the photo - but it looks a bit hairy? If it is it is perhaps H.elodes (Marsh) with reddish sepals or H. hirsutum (hairy)with black glands on the sepals?
If it is perforatum - the leaves, when held to the light will be have slight holes visible with a lens or even the naked eye, it will be hairless and the sepals should be smooth in outline and acutely pointed?
