ARBORETUM AND PRUTICETUM. PART III. 



1861 



p. 107. Leaves somewhat lanceolate-oblong ; obtuse at the base, quite entire; downy beneath. Fruit 

 on short thick stalks. (Humb. et Bonp.) A tree, from 25 ft. to 30 ft. high. Branches round, covered 

 with minute tubercles ; younger ones somewhat hairy. Leaves about 2 in. long, leathery ; glabrous 

 above ; covered with pale down beneath. Petioles about 2 lines long. Female flowers in the axils 

 of the leaves, almost solitary, on short thick pedicels. Cups somewhat top-shaped, closely imbricated. 

 Scales oval, covered externally with a powdery down, acute. Nut ovate, terminated by the elongated 

 style. A native of the low mountains of New Spain, near Santa Rosa. Humboldt called this species 

 Q. crassipes, from the extreme thickness and shortness of the stalks of the acorns. Its leaves ter- 

 minate in a mucro. 



Q. lanceolata Humb. et Bonp. PI. ^quin., t. 81., and our fig. 1863., Michx. N. Amer. Syl., 1. 

 p. 107. Leaves lanceolate, quite entire, wavy ; the axils of the veins bearded beneath shinin above. 

 Fruit sessile. Scales of the cup turned backwards. 



1863 



(Humb. et Bonp.} A tree, from 30 ft. to 40 ft. high. 

 Branches alternate, covered with small tubercles, 

 glabrous ; younger ones, and the petioles, clothed 

 with stellate down. Leaves 2 in. to 3 in. long, and 

 1 in. broad ; shining on both sides, leathery. Petioles 

 about A in. long. Female flowers axillary, nearly 

 sessile, and solitary. The cup is in the shape of a 

 goblet, with the scales turned the contrary way ; oval, 

 glabrous, and convex on the outside. Nut ovate, 

 twice the length of the cup. A native of the tem- 

 perate regions of New Spain, between Moran and 

 Santa Rosa : where it forms immense forests, at an 

 elevation of 5400 ft. (900 toises). The wood is very, 

 hard, and will last a long time when driven into the 

 earth, or exposed to wet ; on which account it is 

 much esteemed by the Mexicans, and is used in the 

 works of the mines. This oak is remarkable for its 

 leaves, which are entire and wavy on the margin ; for 

 the goblet-shaped cups of its acorns, the scales of 

 which all point towards the tree, instead of from it ; 

 and the property which is possessed by its wood of 

 resisting decay in water. 



Q. reticulata Humb. et Bonp. PI. JEquin., t. 86., 

 and our fig. 1865., Michx. N. Amer. Syl., 1. p. 110. 

 leaves oboval ; emarginate at the base ; slightly 

 toothed towards the tip, rugged ; reticulately veined 

 and minutely downy beneath. Fruit sessile, on a 

 pedunculated raceme. (Humb. et Bonp.) A very lofty 

 tree; younger branches downy. Leaves 2 in. long, a 

 little emarginate at the base. Female flowers in ax- 

 illary solitary spikes, about the length of the leaves 

 Cup campanulate, closely imbricate. Scales membranaceous, lanceolate, externally downy, attenuated 

 on both margins, somewhat recurved. Nut ovate, twice as long as the cup ; terminated by the per- 

 sistent style. A native of arid mountains in New Spain, between Guanajuato and Santa Rosa, 

 forming considerable forests, at an elevation of about 6700 ft. (1450 toises). It attains a great height, 

 and the trunk is straight, and of great diameter. The wood is used in building. 



Q. chrysophljlla Humb. et Bonp. PI. .flSquin., t. 87., and our fig. 1864., Michx. N. Amer. Syl., 1. 

 p. 108. Leaves oblong ; obtuse at the base ; 3 5-pointed at the apex ; yellow beneath. Female flowers 

 in many-flowered pedunculated clusters. (Humb. etBonp.} A tall tree; younger branches furrowed, 

 as if with a powdery down. Leaves alternate, on long footstalks, 2 in. long, membranaceous ; shining
