The therionarca, altogether a different plant from that of
the Magi,1 grows in our own climates, and is a branchy plant,
with greenish leaves, and a rose-coloured flower. It has a
deadly effect upon serpents, and the very contact of it is suf-
ficient to benumb2 a wild beast, of whatever kind it be.
1 See B. xxiv. c. 102. The plant here spoken of has not been identified,
but the Epilobium angustifolium, montanum, tetragonum, &c., varieties of
the Willow-herb, have been suggested. They are destitute, however, of
all poisonous qualities.
