FAGACEAE. — QUERCUS 235 



row, mostly entire, and more or less rounded at the base, and in consequence it has 

 remained obscure. His material on which he founded his Quercus glauca, 8 var. 

 stenophylla is much more typical of the species. It consists of leafy branches with 

 oblong-lanceolate acuminate leaves, attenuate at the base, from 1.2 to 2.7 cm. 

 wide, and sharply toothed above the middle; the petioles are from 1 to 1.5 cm. long 

 On specimens before us the leaves vary in width from 0.8 to 3 cm., are rounded or 

 attenuate at the base, and the petioles vary from 0.5 to 2.5 cm. in length. The 

 leaves are whiter on the undersurface than those of the very closely related 

 Q. glauca Thunberg, and the branclilets are always pale gray and not dark and 

 purplish as in Thunberg's species. The fruit ripens in one season. In the Gray 

 Herbarium there is a specimen from the Liukiu Islands, collected by C. Wright 

 (No. 307) and named Q. salicina, but it is Q. Miyagii Koidzumi (in Tokyo Bot. 

 Mag. XXVI. 167 [1912]), a very distinct species. 



Pictures of Q. salicina will be found under Nos. x575, x578 of the collection of 

 Wilson's Japanese photographs.

 CHINA. Hongkong: without precise locaUty, common, November 5, 1903,

We have before us a co-type of Blume's Q. salicina, and it is obvious that Hance 

 and Schottky are correct in considering the Hongkong plant distinct from the Jap- 

 anese tree. The confusion was primarily caused by Blume basing his species on 

 fragmentary material, but even the leafy shoots are quite different. In Blume's 

 co-type of his species the year-old shoot is pale gray, densely lenticellate and 

 channelled; the leaves are slightly oblique and rounded or very abruptly narrowed 

 and broadly cuneate at the base, the apex is acuminate and mucronate and the 

 margin is entire or sparingly toothed above the middle ; the petiole is from 5 to 12 mm. 

 long. The Hongkong plant has dark purphsh year-old branchlets, leaves attenuate 

 at the base, rounded or more rarely obtuse at the apex, usually entire, but occasion- 

 ally with one or two obscure rounded teeth, and petioles from 2 to 5 mm. long. With 

 complete material the differences are verj^ great, but it is only necessary to mention 

 here that in the Hongkong plant the fruit is very much larger and does not ripen 

 until the second season, while the Japanese plant ripens its fruit in one season. 

 Moreover, there is no species of Quercus of the section Cyclobalanops known from 

 Japan in which the fruit does not ripen until the second year. There has been con- 

 siderable confusion about Hance's name, but there never lias been any doubt as to 

 the plant he applied it to. Since Fortune'.s Q. bainbusacfolia is a nomen nudum, and 

 Master's Q. bambusifolia is a synonym of Q. myrsinaefolia Blume, Hance's name 

 remains valid under the International rules.
