FAGACEAE. — QUERCUS 237 



Quercus gilva Skan in Jour. Linn. Soc. XXVI. 514 (non Blume) (1899), quoad 



specimina Henryana. 

 Cyclobalanopsis Delavayi Schottky in Bot. Jahrb. XLVII. 657 (1912). 

 Synaedrys Delavayi Koidzumi in Tokyo Bot. Mag. XXX. 191 (1916). 

 CHINA. Yunnan: Mengtsze woods, alt. 1800 m., A. Henry (Nos. 10504, 

 10504=^; tree 6 m. tall). 



As Schottky points out, this species is easily distinguished from Q. gilva Blume 

 by its biennial fruit. In addition to Henry's specimens Skan refers other material 

 to Blume's species, but we have seen no material from China referable to this 

 Japanese tree, and we doubt if it grows there. 



Quercus Schottkyana Rehder & Wilson, n. nom. 

 Cyclobalanopsis glaucoides Schottky in Bot. Jahrb. XLVII. 657 (1912). 

 Quercus glaucoides Koidzumi in Tokyo Bot. Mag. XXX. 200 (non Martens & 

 Galeotti) (1916). 

 CHINA. Yunnan: Szemao, woods, alt. 1600 m., A. Henry (Nos. 11770, 

 11770% 11698% 116981^; bush or tree 2-6 m. tall). 



This species is very distinct from its allies and is characterized by its long female 

 aments and by its very small acorn and cup. Schottky suggests that Q. glauca, 

 var. villosa Skan may belong here, but to us this seems highly improbable, and we 

 are doubtful if Skan's plant is entitled to any rank to distinguish it from the 

 type.
