'''Bog-laurel''' (''Kalmia polifolia'') is an evergreen [[shrub]] of cold acidic bogs, in the family [[Ericaceae]]. It is native to north-eastern [[North America]], from [[Newfoundland (island)|Newfoundland]] to [[Hudson Bay]] southwards. Its leaves are arranged oppositely on the branch. They are waxy with an entire, revolute margin. The base of the [[Petiole (botany)|petiole]] is pressed against the stem. Below each leaf base there are ridges, where it appears as though a part of the leaf is curled around the circumference of the stem. This is especially noticeable lower on the plant. Bog-laurel contains [[grayanotoxin]], which when ingested lowers [[blood pressure]], and may cause respiratory problems, dizziness, vomiting, or [[diarrhea]].<ref name=Pojar>{{cite book |coauthors=Paul Alaback, Joe Antos, Trevor Goward, Ken Lertzman, [[Andy MacKinnon]], [[Jim Pojar]], Rosamund Pojar, Andrew Reed, Nancy Turner, Dale Vitt |editor=Jim Pojar and Andy MacKinnon |title=Plants of the Pacific Northwest Coast |edition=Revised |year=2004 |publisher=[[Lone Pine Publishing]]|location=[[Vancouver]] |language=[[English language]] |isbn=978-1-55105-530-5 |page=53}}</ref> {{Inc| Kalmia polifolia, Wang.
