Gailes, Fr. ; Farber Eiche, Ger. (Our Jigs. 



1G38. and 1639. ; the first from Olivier, and the ^^ 



second from Du Hamel.) Leaves ovate-oblong, s!:;^ 

 very smooth on both sides, 

 deepl}^ toothed, somewhat 

 sinuated, deciduous. Fruit 

 sessile ; ri[)ening the second 

 year. Calyx tessellated. 

 Nut elongated, nearly cy- 

 lindrical. (Sm.) A decidu-

Africa. Height 4 ft. to 6 ft. Introduced ?. 



The leaves are about 1 or 1^ inches long, bright green, smooth on both 



sides, but paler beneath ; their serratures are deep and broad, not acutely 



pointed. Fruit solitary, nearly sessile. Cup slightly downy ; its scales not 



very distinct. Acorn two or three times longer than the cup, smooth, nearly 



cylindrical. Olivier observes that this plant, besides producing the galls of 



commerce, bears a number of different kinds of this 



excrescence, which are neglected as useless. The de- 

 scription and figures of these galls, and of the insects 



which cause their production, are in our first edition.

are described in our first edition. 



Q. mannijera Lindl. Bot. Reg. Chron., 1840, No. 72., 



and also Q. mongolica, appear to be nothing more than 



varieties of Q. sessiliflora. The latter produces the Koor- 



distan manna, a sweet glutinous substance, which oozes 



from the upper surface of the leaves during the hottest months of the yeai".
