210 WILSON EXPEDITION TO CHINA 



add that in all the specimens of L. Henryi before us the petioles are always longer 

 and the leaves narrower; the cup is never thickened and tubercled and the bracts 

 subtending the branches of the male inflorescence are ovate-lanceolate acuminate 

 and three times the size of those on L. spicata Rehder & Wilson. Lithocarpus 

 Henryi occupies a distinct geographical region, and until our knowledge of the 

 Chinese Oaks is more complete we think it is best to maintain it as a distinct 

 species. 



Pictures of this tree will be foimd under Nos. 499, 538, 650 of the collection 

 of Wilson's photographs and also in his Vegetation of Western China, Nos. 425, 

 427, 430.

 12329% 12329^ 12329% 12329^ 12329"). 



Schottky also includes Henry's No. 9636, but that has leaves pubescent on the 

 under side and the male inflorescence is much shorter and the flowers are different. 

 In the neighborhood of Mt. Omei L. viridis is a common evergreen tree. The 

 fruit is biennial.
