Abstract
I surveyed the flora of wild vascular plants in Shikoku Research Center, Forestry and Forest Products Research Institute, which is located on a lowland hill in a warm-temperate zone, and revised the previous flora list published in 2006, following APG III system. As a result, 360 species, 277 genera, 110 families of vascular plants (38 of ferns, 6 of gymnosperm and 316 of angiosperm) are recorded. Thirty-nine species (10 of ferns, 3 of gymnosperm and 26 of angiosperm) are newly added. Shade-tolerant plants such as evergreen ferns (e.g. Crytomium fortune) and evergreen trees (e. g. Elaeocarpus zollingeri) and disturbance-adapted weeds (e.g. Sonchus asper) are newly recorded. It seems that the flora changes as the environment of the Shikoku Research Center changes with transplanting of the experimental forests and with the growth of the forests and the arboretum.
