Western Szech'uan: west of Kuan Hsien, Pan-lan-shan, up- 
lands, alt. 3500-4500 m., June 24, 1908 and October 1910 (Nos. 
3632*, 4372^, 4580, type). 
This new species is perhaps most closely related to Q. semicarpifolia Smith, but 
that species has an annual fructification and a larger, nearly globular acorn. 
western Szech'uan these two species grow in the same regions at similar altitudes 
and superficially very strongly resemble each other. Both are gregarious plants 
and on the windswept uplands cover large areas in the form of scrub; in sheltered 
places they develop into small trees. In both the under surface of the leaves 18 8 
rich golden brown, but in Q. aquifolioides they persist at least until the end of the 
third season. Quercus spinosa David agrees with our new species in having bienni 
fruit, but in David’s species the leaves at maturity are glabrous, except the mid- 
rib in its lower half, and the tomentum on the young leaves is gray, never den 
brown; the veins are more spreading and the leaf strongly bullate; the scales of the 
cup are very short, firmly appressed and quite distinct one from another.
