【Publication of "Taisei Honzo Meiso", Ito's first botanical book.】
Based on Thunberg's "Flora Japonica" which Siebold had presented to him, Ito wrote "Taisei Honzo Meiso" in 1829, when he was 27 years old.
"Taisei Honzo Meiso" chiefly presents information about plants in the West. There is information indicating that in order to publish this book, he had to raise a huge amount of money, which he did by offering his land and house as security.
Ito became famous because of the publication of this book.
In this book he introduced the Linnaean plant classification system for the first time in Japan, explaining it in simple language.
He invented Japanese equivalents for many botanical words in English, such as "pollen", "stamen" and "pistil" and explained the functions of flowers in detail.
Some of Ito’s Teachings
“Make anything you discover or study known to the public, in any way you can. If what you make public is alleged at a later date to be wrong, you should discuss the issue with the person who made the allegation. Acting this way will surely lead to the advancement of science.”
“Do not hesitate to make what you have discovered and thought known to the public, without hesitating because you think that you may be wrong or get laughed at if you announce your idea. Even if you are wrong or get ridiculed, consideration of your idea will surely be useful to you and to all other people, as well."
