ABSTRACT
The Flora of the Japanese sand-dunes, influenced and determined by the dune-sand and salt-dust of the sea-water, is indeed not very rich in species, yet is characterised by some general properties and a number of very frequently occurring plants. The existence of the forest and the beginning of the high Alpine Flora depend here primarily not upon the temperature, but upon the winds, which often allow the latter to exist, where the growth of trees is impossible. The considerable increase thus made of late to the knowledge of the Japanese flora is principally to be attributed to a more exact investigation of the mountainous interior. As, however, the Flora of Japan exhibits few aromatic plants, so, too, it has few with a tomentum on their green organs, though on the other hand, many are inclined to parti-coloured foliage in a high degree.
