薮茗荷(ヤブミョウガ) Pollia japonica

　ヤブミョウガが小川のほとりに生えていました。湿った場所が好きなようです。我が家にはミョウガが生えていますが、両者で花は全く異なります。葉はよく似ていますが、ミョウガのほうが長いようです。ヤブミョウガは、ツユクサに分類され、ミョウガはショウガ科です。

　A bush ginger has been growing on the bank of a stream. They seem to like damp places. Japanese ginger grows in my garden, but the both flowers are completely different. The leaves are similar to each other, but Japanese ginger's leaves a little longer. Pollia japonica is classified as Commelinaceae, and Japanese ginger belongs to the Zingiberaceae family. Both plants are referred to as ginger in Japan.
