- In the Nature Conservation Series of postage stamps, a 50-yen stamp showing “Koshinso“, a rare species of plant, has been issued on June 8.
- Koshinso (pinguicula ramosa Miyoshi) is a perennial plant belonging to Lentibulari-aceae (dicotyledon). The species peculiar to Japan is distributed in the extremely limited area – on alpine walls near Nikko, Tochigi Prefecture.
- The leaves, oblong in shape, are about one centimeter long and have short glandular hairs on their surface; the hairs secrete mucus to catch small insects and digest them.
- A 3-8 centimeter long stalk grows between two leaves in June or July, and a light purple flower like a violet blooms at its top.
- The species was discovered in Mt. Koshin in Ashio Town, Kamitsuga County, Tochigi Prefecture, in August, 1890 by Dr. Manabu Miyoshi; hence the name of the plant. The area in the mountain where the plant grows was designated as a Natural Monument on March 3, 1921 by the Government. It was designated a Special Natural Monument on March 19, 1952 in order to protect it from being ruined.
