 Engravings. Tratt. Arch., 1. No. 14. ; our fig. 124._in p. 450, 451. ; and the plate of this species in 



our Second Volume. 



Spec. Char., $c. Leaves cordate, roundish, 5-lobed ; lobes bluntish (or 

 pointed), repandly toothed, velvety beneath. Corymbs pendulous. Pe- 

 dicles hairy. Fruit rather hairy, with the wings somewhat diverging. 

 (Don's Mill., i. p. 649.) The flowers are pendulous, pale, and few in the 

 panicle. A large tree, with the general habit of A. Pseudo-Platanus, but 

 apparently of more vigorous growth ; a native of Hungary, Croatia, and 

 many parts of Italy; and introduced into England in 1825. "On all the 

 hills and lower mountains of the kingdom of Naples, in Camaldoni, Cas- 

 tellamare, and the Abruzzi, it is found abundantly, growing, usually, to the 

 height of 40 ft. It is extremely striking, with its reddish purple branches, 

 in the wood of Lucania, between Rotonda and Itubia ; and, in the Basi- 

 licate, and Calabria, it is said, by Tenore, to acquire colossal dimensions. 

 It is certainly very singular that so fine a tree as this, occupying so large a 

 tract of country frequently visited by English tourists, should be almost 

 unknown in this country; and yet, although it is perfectly hardy, and very 

 easily multiplied, it is scarcely ever met with in any but botanical collec- 

 tions." (Pen. Cyc., vol. i. p. 77.) There is a noble specimen of this tree in 

 the garden of the London Horticultural Society at Chiswick ; which, 

 though only 10 or 12 years planted, in 1835 had attained the height of 

 2G ft., with a trunk 5| in. in diameter, as shown in our plate in Vol. II.

fiynvnymes. A. carolinianum Bolt. ; A. trilob&tum, in the London Hort Soc. Gard. in 1835. 

 Engravings. A leaf is shown in Pen. Cyc., vol. 1. p. 76. ; and several in our Jig. 125. in p. 452. 



Spec. Char., %c. Leaves heart-shaped, 3-lobed, nearly equally serrated, 

 nearly smooth beneath. Clusters sessile. The stalks of the female flowers 

 simple, of the male flowers branched. Calyx bearded internally. Keys 

 smooth, diverging but little. (Pen. Cyc.) This species, according to 

 Pursh, inhabits North America, between New Jersey and Carolina, in deep 

 pine and cedar swamps. It was found on the west side of the Rocky 

 Mountains, about the sources of the Columbia, by Douglas; but Dr. 

 Hooker says the specimens sent home by him are too young to enable him to 

 form an opinion as to the correctness of the name. There are two plants 

 of this species, under the name of A. trilobatum, in the garden of the Lon- 

 don Horticultural Society, where they form low trees, or bushes, about 

 10ft. high. In its native country, the tree is said to grow to the height of 

 20 ft. The plants named A. barbatum, in the London Horticultural So- 

 ciety's Garden, and in Messrs. Loddiges's arboretum, and in some of the 

 nurseries in 1835, seem to be A. jolatanoides. The leaves, and the general 

 appearance of the plant, are those of A. Pseudo-Platanus, diminished, in 

 all its parts, to one third of its usual size. This species was introduced in 

 1812; and plants of it, under the name of A. trilobatum, may be obtained 

 in some of the nurseries. 



D. Leaves 5, rarely 1-lobed.
