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 found under Nos. 499, 538, 650 of the collection 
of Wilson’s photographs and also in his Vegetation of Western China, Nos. 425, 
427, 430.

123295, 12329}, 12329°, 123294, 12329"). a 
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 à common evergreen tree. The 
fruit is biennial.
