234 WILSON EXPEDITION TO CHINA 



A specimen in the Gray Herbarium collected in the Liukiu Islands by C. Wright 

 (No. 306) differs markedly from the type in the under surface of the leaves, which 

 are clothed with a loose floccose gray tomentum. 



Franchet reduces this species to a variety of Q. Ilex Linnaeus and makes other 

 Chinese Oaks varieties of Linnaeus's species. In this he is followed by Skan, but 

 both have overlooked the important character of the fruit. In Q. Ilex it matures in 

 one season, but in all the Asiatic Oaks referred to it as varieties by Franchet and 

 Skan the fructification is biennial. Von Seemen (in Bot. Jahrb. XXIX. 289 (1900)) 

 refers specimens collected by A. von Rosthorn at Nanch'uan, southeastern Szech'uan, 

 to Q. Ilex and remarks that they resemble Kotschy's var. lanceolata. His brief 

 description suggests to us a species very closely related to Q. Franchetii Skan. 



We have seen no specimen of Quercus from China or any other part of eastern Asia 

 that is in any sense referable to Q. Ilex Linnaeus, and we are strongly of the opinion 

 that neither the species nor any of its varieties or forms grow there. Franchet and 

 other authors evidently attached too much importance to the general appearance 

 of the leaves and overlooked important characters in the fruit. In China there are 

 a number of different species of Quercus in which the leaves exhibit the same varia- 

 tions as are found on those of Q. Ilex. They are spiny or entire, pubescent or 

 glabrous, according to the different ecological conditions under which they grow, and 

 these same variations occur on different species of Oaks native of western North 

 America.
