Distribution of Popular Plants in the Miyagi Prefecture, North Japan

Abstract

Distribution maps of 31 popular plants (Tab. 1) in the Miyagi Prefecture (140°15'E ～141°43'E, 37°45'N～39°00'N), north Japan, were prepared based on informations from local botanists and on author's field observations. Justicia procumbens was not detected in this area. Mallotus japonicus, Indigofera pseudotinctoria and Trachelospermum asiaticum showed coastal distribution in northern half of the prefecture as they are close to their northernmost distribution. Rate of occurrence in the northern part of the prefecture is less than that in the southern part for all the target plants suggesting the occurrence of a line of discontinuity in the amount of plant distribution.
