PART III. 



species is at White Knights, near Reading : it is about 60 ft. high ; and, at a 

 distance, the tufting of the masses has a very singular appearance. 



Geogrciphy, History, ^c. This species is found in Canada, and in the northern 

 parts of theUnited States : it is less common towards the south ; and, in Virginia, 

 the Carolines, and Georgia, it is found only on the Alleghany Mountains, "it is' 

 abundant in Tenessee, on the borders of Lake Erie and Lake Ontario, on 

 loose, deep, fertile soil. The wood of this tree is white and tender ; and, in 

 the northern states of America, where the tulip tree does not attain a timber 

 size, it is used for the panels of carriage bodies, and the seats of chairs. On 

 the Ohio, the images affixed to the prows of vessels are made of this wood ; and 

 the inner bark is formed into ropes, as that of the T. europse^a is in the north 

 of Europe. This lime was cultivated by Miller in 1752, but has not been very 

 extensively distributed. There are trees of it of 10 years' growth in the Lon- 

 don Horticultural Society's Garden ; and it is propagated, generally by graft- 

 ing, in some of the British and Continental nurseries. Price, in London, 2s. 6d. 

 a plant; at Bollwyller, 1 franc 50 cents; and at New York, 50 cents. 



^ T. a. 2 laxiflora. The loose-cymed-flowered American Lime Tree. 

 St/nonyme. T. laxiflbra Michx., Pursh, Dec, Uayne's Dendr., and Don's Mill. 



Description, Geography, Sfc. Petals each with a scale at the base, 

 inside. Leaves cordate, gradually acuminated, serrated, membrana- 

 ceous, smooth. Cymes loose. Petals emargmate, shorter than the 

 style. Fruit globose. (Z>o?z's ilir«7^.,i. p. 553., adapted.) A most 

 distinct species, according to Pursh. G. Don observes that it is 

 generally confounded with T. glabra ; which, if the trees in the 

 London Horticultural Society's Garden be correctly named, is not to 

 be wondered at : for their general resemblance is so great, that we 

 have no doubt of their being essentially the same species, notwith- 

 standing the comparatively loose cymes of the flowers, which, 

 however, we have never seen ; no plants of this variety, that we 

 are aware of, having yet flowered in Britain. This variety is said 

 to be found from Maryland to Georgia, near the sea-coast, where it 

 grows to the height of 50 ft., and produces its yellowish-white 

 sweet-scented flowers from May to July. It was introduced into 

 England in 1820, and is but sparingly cultivated. There is a plant 

 6 ft. or 8 ft. high in the London Horticultural Society's Garden.

Description. Petals each with a scale at the base inside. Leaves 

 truncate at the base, somewhat cordate and oblique, denticulately 

 serrated, pubescent beneath. Petals emarginate, shorter than the 

 style. Fruit globose, even. (Don's Mill., i, p. 553.) This variety is 

 of much less vigorous growth than the preceding; the leaves are 

 much smaller, and the branches more slender. The leaves are most 

 pubescent after their first expansion : as they increase in size, a part 

 of the pubescence falls off, and the hairs which remain form little 

 starry tufts. The colour of the bark is dark, and shows that it is more 

 nearly allied to T. americana than to T. a. laxiflora. It is a native 

 of the southern parts of theUnited States and the Floridas, where it 

 grows on the borders of rivers and large marshes, where the soil is 

 cool and rich, and not subject to inundation. It is the only variety 

 found in the maritime parts of Carolina and Georgia. Michaux found 

 it principally in the neighbourhood of Charleston, growing to the 

 height of 40 ft. or 50 ft., and having the general appearance of the 

 common American species. Its leaves, he says, differ widely in size, 

 according to the exposure in which they .grow : in dry and open 

 places they are only 2 in, in diameter;* but in cool and shaded
