of the empire only the evergreen Ligustrum Japonicum of the south becomes a tree. Of the 

 other species, Ligustrum medium is much more common than Ligustrum Ibota ; at the north

 Japan, Ligustrum Ibota is also found. 



In the remaining Gamopetalous orders of trees Japan possesses only Ehretia acuminata, 

 which inhabits the Loochoo Islands, and possibly reaches the southern shores of Kuyshu, a 

 small tree, which I saw only in the Botanic Garden of Tokyo, and the beautiful Clerodendron 

 trichotomum, which in late summer enlivens the banks of streams with its great masses of 

 tropical foliage and brilliant flowers, and in Yezo often attains to the size and habit of a small 

 tree.
