 staminate arnent pubescent; flowers remote, perianth 5 lobed, stamens 5 

 with ovoid anthers. Fruit maturing in 2 seasons, 1-5 together, peduncled,

W. Szechuan. 



Closely allied to Q. semicarpifolia, from which it differs by the acorn, 

 which is not ovoid, and not globular, and by the biennial fruitification. 

 It occurs in association with Q. semicarpifolia . 



Quercus gilliana Render & Wilson. 



Evergreen shrub or small tree to 6 m. tall. Branchlets purplish- 

 brown, at first pilose, finally glabrescent. Leaves coriaceous, subsessile, 

 oval to obovate, apex rounded, spiny pointed, base subcordate to slightly 

 auriculate, sinuately spiny-toothed, quite glabrous at maturity, 12 mm. 

 long. Fruit 2-4 together, subsessile, ripening in one season ; acorn 

 ovoid, cup hemispherical with triangular-ovate, glabrescent, scales, 

 enclosing nearly 1/2 of the nut. 



W. Szechuan. 



Distinguished from Q. semicarpifolia by the fruit, which is not 

 globular and embraced nearly 1/2 by the hemispherical cup. This 

 species usually occurs as scrub over large areas. 



Quercus oxyodon Miquel. 



Half evergreen tree up to 10 m. tall. Winter buds angular with gray, 

 acute, mucronate scales. Leaves oblong, acuminate, serrate, rounded or 

 broadly cuneate at the base, with numerous prominent, close, deeply 

 impressed lateral veins, glaucescent and silky pubescent beneath, 6-1 

 cm. long. Fruit ripening in 1 year, spicate, sessile; acorns ovoid to 

 subglobose, about 2 cm. long, broader than high ; cup saucer-shaped with 

 several irregular, crenulate, concentric rings which are grayish tomentose 

 and not deeply appressed. 



Hupeh, Szechuan to India. 



Common in Western China. The leaves persist through the winter 

 and are replaced by the new leaves in the spring.
