Rhododendron Chrysanthum. 
Potsonous Prorerties.—The acridity of Kalmia latifolia j 
is so great as to render it poisonous, The honey which bees — 
prepare from the materials they find in the flowers of Azalea 4 
pontica, is reported, both by ancient and modern authors, to — 
be poisonous. M. Richard also mentions Ledum palustre 
and Andromeda mariana as dangerous; A. ponticum and 
A. maximum are to be suspected. Ledum is said to be very 
narcotic.
