hand some tree, from 40 ft. 

 to 50 ft. high ; found on 

 the mountain of Salak. It 

 is nearly allied to Q. glaura 

 Thunb. ; but the leaves 

 are broader, less acute at 

 the base, and not glau- 

 cous beneath. (/>///><.) 

 The acorns are of a very 

 singular shape, and arc en. 

 closed in the cup. 



O. lincata Blume Fl. 

 Jav., t. 19. ; and our Jig. 

 1851. The parallel-veined 

 Oak. Leaves oblong-lan- 

 ceolate, sharp at both 

 ends, serrated or entire ; 

 glabrous above, glaucous 

 and downy beneath. Nuts 

 small, scarcely reaching a 

 line above the cup ; crown- 

 ed at the tip by a long 

 umbo. A large tree, at- 

 taining the height of 80 ft. 

 and upwards. A native of 

 the west of Java, in woods, 

 at elevations of 5000 ft. to 

 6000ft. (Blume.)

App. viii. Mexican Oaks not yet introduced. 



The first 22 of the following oaks are described and figured in Humboldt and Bonpland's magni- 

 ficent work on the plants of Mexico, entitled Plantce JEquinoctiales. The 14 that follow these are 

 taken from Nees, as quoted in Rees's Cyclopaedia ; and many of them are probably indenttcal with 

 those of Humboldt.

 p. 109. ; Roble de Duela, Span. Leaves on long footstalks, oval-lanceolate ; acute at each end, 

 remotely toothed with bristly teeth, quite glabrous. Fruit almost solitary, sessile. (Humb. et Bonp.) 

 A tall tree, glabrous in every part, except the cup. Branches alternate ; younger ones covered with 

 round tubercles. Leaves crowded towards the tips of the branches, 3 in. to 4 in. long, somewhat 

 leathery. Petioles 1 in. or 1J in. long ; a little thickened towards the base, slender. Female 

 flowers axillary, almost solitary and sessile. Cup goblet-shaped, closely imbricated. Scales oval, 

 membranaceous; covered on the outside with a peculiar down, scarious on their margins, and 

 blunt at their apex. Nut ovate, obtuse, terminated by the persistent style. Very common in the 

 forests near Xalapa, in New Spain, at an elevation of about 4000 ft. (677 toises). From the wood, 

 which much resembles that of Q. Rbbur, the Spaniards have given it the name of Roble de Duela, 

 that is, the Timber Oak ; a name which indicates that this oak is applied to the same uses as 

 Q. .Robur. This is a valuable tree, and it will one day become of such great importance in Mexico, 

 that the inhabitants ought to take more pains to increase it. Michaux describes it as a very lofty 

 tree, with a trunk 2ft. in diameter. It bears abundance of acorns, which, though they soon ger- 

 minate, might, with proper care [packed in moist Sphagnum], be sent to England.
