accords very badly with that of LINNÆUS's _ochroleuca_, they
have been generally considered in this country as one and the same
plant, distinguished by the name of POCOCKE's Iris, Dr.
POCOCKE being the person who, according to MILLER, in
his time first introduced it from _Carniola_ (by inadvertence spelt
_Carolina_, in the 6th 4to edition of the Dictionary). There are
grounds, however, for suspecting some error in the habitat of this
plant, for had it grown spontaneously in Carniola, it is not probable
that SCOPOLI would have omitted it in his _Flora Carniolica_.

Leaving its place of growth to be more accurately ascertained hereafter,
we shall observe, that it appears perfectly naturalized to this country,
growing luxuriantly in a moist rich soil, and increasing, like most of
the genus, very fast by its roots. It flowers later than most of the
others.
