ResumoSince Linmean period up to this date we have known no other genera than Salix and Populus in the family Salicacex.The present genus which I am introducing is a new addition to the family.It is a big magnificent tree growing along the river-sides in North-Korea.The trunks become one or one and half meter in diameter and the height of tree becomes more than thirty meters.Its appearance is in every respect a Salix.Its bud has two or three imbricated scales like S. glandulosa and some others.The outermost one of the scales wholly envelopes the inner ones, though it is imbricated at its margin.The tree is dicecious like a Salix.The male catkins are drooping like Populus, but have neither gland nor cup-like disk.The female catkins, too, have neither gland nor cuplike disk, but have very fugaceous membranaceous five-nerved bracts.The ovaries are blunt at their apices and have two distinct forked styles.The styles are articulated and deciduous.In May of 1917, a staff of the Bureau of Forestry in North-Korea collected the specimens bearing the male catkins near Nanshadoko along the Jalu, and in the next year Mr. TSUTOMU ISHIDOYA found the male tree near Taichuri of South-Hamgyoeng.Those specimens were delivered me by Messrs. MASATOMI FURUMI and T. ISHIDOYA, from which I made the descriptions of Salix splendida (see the Tokyo Botanical Magazine Vol.XXXII, p. 215.Oct. 1918).There I pointed that the plant may represent a distinct section by the lack of the gland.We have had many fruit-bearing specimens, but no female flowers reached us until Mr. KIICHI IWATA has collected them in May of this year.Examining his specimens I found that this plant represents a distinct genus.The name Chosenia is derived from Chosen or Korea.It distributes all over those districts where
