192 WILSON EXPEDITION TO CHINA 



Western Hupeh: Hsing-shan Hsien, woods, alt. 1600-2600 m., 

 May 31, 1907 (No. 715, type); Fang Hsien, A. Henry (No. 6793). 



It is unfortunate that our material of this interesting tree is so incomplete, yet 

 it is so distinct from all known species that we do not hesitate to give it a name. 

 The leaves are shining green on both surfaces, even when quite young, and the den- 

 tation is remarkable. The margin is sinuate (sometimes obscurely so) and is 

 convex between the secondary veins, which are usually projected from the base of 

 the sinus and form short triangular teeth of irregular size often reduced to a small 

 and thickened mucro. Wilson paid considerable attention to the Chinese Beeches 

 and states that this new species is easily distinguished in the woods by its thick 

 and always single trunk and by its bark, which is a much duller gray than that 

 of the other two species. The branches are thick and spread to form a broad 

 flattened or rounded crown. In northwestern Hupeh and in northeastern Szech'- 

 uan this new species is fairly common in mixed forests and with F. Engleriana 

 Seemen often forms pure woods. Henry's No. 6793 is by Skan (in Jour. Linn. Soc. 

 XXVI. 527 [1899]) doubtfully referred to Oliver's F. sylvatica, var., which is the 

 same as F. Engleriana Seemen. 



Plants of this and the other two Chinese species brought home by Wilson in 1911 

 are growing in the Arnold Arboretum. 



A picture of this new Beech will be found under No. 0132 of the collection of 

 Wilson's photographs.
