I was just researching toxicity of Kalmia latifolia last week ironically. Both Rhododendron and Kalmia are attributed to imparting toxicity to honey make from their pollens. Kalmia angustifolia *and* Kalmia latifolia are both listed in this, though there needs to be signifcant amount of it around for the honey to actually be lethal. Here in nothwestern Florida, at the other end of Kalmia latifolia's range they are not as wide spread as further north but can be locally common and are just as enjoyable. I just found that there where three large specimens growing wild at my neighbors that will be a treat to seen in flower in the spring. As to ancient Greece though, not likely to be Kalmia as it is a North American genus with the possilble exception of the Cuban species. Alani Davis Tallahassee, Fl
