Honeybees and pollen

Xenophon was the first but not the last to describe poisoning by honey from
plants with toxic nectar. Kalmia latifolia is well-known as a source of
this. Deaths have occurred in North America. Rhododendron and other Kalmia
spp. are also responsible. But they sure have pretty flowers, though they
are not bulbous.
