Note E310 — 51.

"The May weed doth burn" (Anthemis cotula, L.). The juice of this plant is possessed of an acrid blistering property which renders it extremely noxious to reapers. The irritating effects are produced in a still greater degree by the seed when ripe, and are mostly manifested in the lower extremities, from the close adhesion of the seeds by their rough surface, aided by the friction of the shoe, causing first abrasion, then active inflammation, and even ulceration. Dr. Bromfield (Flora Vectensis) says: "I have been repeatedly assured by the peasantry that they have known men incapacitated for work, and laid up, from the injurious operation of this noxious weed, for days together in harvest time."
