Abstract:

We investigated native plant survival in early modern (Edo period), modern (Meiji, Taisho, and early Showa period), and contemporary (late Showa and Heisei period) metropolis. Modern metropolis developed after industrial revolution alongside of commuter transportation development. Although effects of urbanization on native plant have been studied in many contemporary cities, remnant of native plants in early modern metropolis have not yet known.  
Edo city, former Tokyo, was the third largest city in the world at 1800 with 685 000 population following Peking (1 100 000) and London (861 000), and urbanization continued since those days. We compared herbaceous plant species composition in remnant green spaces of ancient city area of Edo, in green spaces in new reclaimed lands, and in current rural areas.  
The detected remnant species naturally growing in Edo city were Rubus hiusutus ,Viola hondoensis, Viola grypoceras and Taraxacum albidum. They were often found in residence of daimyo feudal lord in Edo period. Taraxacum platycarpum were found at green areas of temple and small sized samurai residence. These remnant plants were not found in new reclaimed green areas.
