upturned toward the end. The habit of the trees is decidedly graceful, 

 but tlie branches are sparse. Near the village of Nanshatongu, on the 

 borders of South Kankyo and North Heian provinces, in forests of Spruce 

 and Fir this Thuja is abundant and small, slender trees are common. In 

 the middle upper slopes of Laoling-san — a peak some 2000 meters high 

 in northern Korea it forms an undergroMh to Pinus pumila Kegel. As a 

 garden plant this Thuja should be valuable as a ground cover and also as a 

 shrub or small tree, I collected seeds on the Diamond Mts. in 1917 and 

 the plants raised from them are now growing well in the Arnold Arboretum.

This new Fir is a most interesting addition to the flora of Korea where it 

 is confined to the volcanic island of Quelpaert and to the Chiri-san range 

 in the south of the peninsula. It is characterized by its pyramidal habit, 

 its deeply fissured rough bark and by its cones with exserted bracts. It 

 combines most of the characters of the three related species Abies neph- 

 rolepis Maxim., A. sachalinensis Mast, and A. Veitchii Lindl. The first has
