On behalf of the botanical community living outside of China I express deep regret at the passing of Wu Zhengyi, one of the greatest botanists of his time.  He knew not only the plants of China but also those of the whole North Temperate Zone better than any of his contemporaries, and made deeply important contributions to our understanding of them, their relationships, and their geography.  Scholarly from a very early age, he was a master of Chinese language and literature.  Raised as the son of an important and distinguished family in Yangzhou, he fit the New China well as it developed during his long and productive life. He was a steadfast friend with whom I had the pleasure of climbing Emeishan in 1980 and co-chairing the Editorial Committee of the Flora of China project for its entire 26-year span.  He taught many and encouraged many, and we shall profoundly miss his presence among us.

唁文

我代表国际植物学界对当代最伟大的植物学家之一吴征镒教授的逝世表示最沉痛的哀悼。吴征镒对中国植物乃至整个北温带植物的熟知程度无同侪能比，并为植物学的传承和发展做出卓越贡献。吴征镒早年便精通中国文学与文化。他出生于旧时扬州官吏世家，后随着新中国的发展投身科学并硕果累累。从1980年同攀峨眉，到26年来始终共事《中国植物志》编辑工作，我一直为拥有如此挚友深感荣幸。永远怀念我们的良师益友吴征镒！
