Derivation. Button-wood refers to the smooth round heads of flowers, which resemble the globular 

 buttons formerly in use, and still seen in some military costumes ; Sycamore to the resemblance of 

 the leaves to those of that tree ; and Cotton Tree to the down detached in the course of the summer 

 from the leaves.

Spec. Char., fyc. Leaves 5-angled, 

 obsoletely lobed, dentate, wedge- 

 shaped at the base ; downy be- 

 neath. (Willd.} A tree, a native 

 of North America, where it grows 

 to the height of 70 ft. or 80 ft. ; 

 with a widely spreading head. It 

 flowers in May; and ripens its 

 seeds in October. Introduced be- 

 fore 1636. The Occidental plane 

 is easily distinguished from the Ori- 

 ental plane, by its leaves being 

 larger, and less deeply lobed (see 

 fig. 1 95 l.a. in p. 2033.); and by the 

 red colour of their petioles ; the petioles of P. orientalis being green. The 

 fruit is, also, much larger, and rather smoother. 



Variety. 



$ P. o. 2 tortudsaj Platane tortillard, Fr. This variety, according to Bosc, was found by 

 Malesherbes in a bed of seedlings. The stem is full of knots, which render the fibres 

 tortuous, and, consequently, difficult to split, like those of the Z/'lmus camp^stris tor- 

 tu6sa, mentioned in p. 1376. ; and, like that variety, it is thought to be suitable for the 

 naves of wheels. We have not heard of its being in cultivation in French nurseries. 

 In the Nouveau Du Hamel, it is stateil that M. Daubenton, fils, who raised many plants 

 of the Occidental platanus for seed, found the varieties almost infinite. 



Description, $c. The American, or Western, plane, in magnitude and general 

 appearance, bears so close a resemblance to the Oriental plane, that, by many 

 persons, they are confounded together. The former, however, is a larger tree; 

 of much more rapid growth than the Oriental plane; with broader and less 

 deeply cut leaves, red petioles, and fruit comparatively smooth, and consider- 

 ably larger. The bark is said to scale off in larger pieces, and the wood to be 

 more curiously veined. In all other respects, the descriptive-particulars of both 

 trees are the same. The rate of growth of P. occidentalis, when placed near 

 water, is so rapid, that in JO years it will attain the height of 40ft.; and a 

 tree in the Palace Garden at Lambeth, near a pond, in 20 years had at-
