Location: Hammarstrand Derivation of the botanical name: Hypericum, hyper, "above," and eikon, "picture," from old practice of placing flowers above an image in the house to ward off evil spirits at the midsummer festival of Walpurgisnacht, which later became feast of St. John. perforatum, perforat, "to bore through, pierce, perforate". Perforated, with the paired leaves joined at the base and thus 'perforated' by the stem. The standard author abbreviation L. is used to indicate Carl Linnaeus (1707 – 1778), a Swedish botanist, physician, and zoologist, the father of modern taxonomy. Location: Hammarstrand
