sometimes seven,) and set on long slender pe- 

 tioles : they are shaped somewhat like those of 

 the lesser Maple, but of a dark green eolour, 

 with their upper surfaees shining : a sweet glu- 

 tinous substance cxsudes through their pores in 

 warm weather, whieh renders them clammy 

 to the touch. In February, before the leaves 

 are formed, the blossoms begin to break forth 

 from the tops of the branches into spikes of 

 yellowish-red, pappose, globular flowers, whieh 

 swell gradually, retaining their roiuid form, 

 to the full maturity of their seed-vessels, which 

 are tliick set with pointed hollow protuberances, 

 and, splitting open, discharge their seeds. It is 

 a native of North America. 



In the second species the leaves have their 

 lobes shorter, and much more sinuated on iheir 

 borders, ending in blunt points, and not serrated. 

 They have also none of those tufts of hair which 

 are found on the leaves of the first sort : its 

 native country is unknown. 



Culture. — These plants are increased by seed, 

 and layers. 



The seed should be sown as soon as it is pro- 

 cured from abroad, in spring, in a bed of light 

 earth, half an inch deep, when the plants will 

 rise some the same year and others not till the 

 spring following, moderate waterings being occa- 

 sionally given, keeping them clean from weeds 

 all summer, and protecting them from severe 

 frost the first two winters. When two years 

 old, plant them out in spring, in nursery rows, 

 two feet asunder, to remain thre*,' or four years, 

 or till wanted for planting out in the shrubberv, 

 or other places. 



Some sow the seeds in pots, or boxes, in order 

 to move them to different situations as the sea- 

 son requires ; and that when the plants do not 

 come up the same year, tlie pots may be plun- 

 ged in a hot- bed in the following spring to for- 

 ward their rising. 



The layers should be made from the young 

 shoots of the preceding summer, by slit-laying, 

 when most of them will be rooted by the follow- 

 ing autunm, though in a dry poor soil they are 

 sometimes two )ears before they are sufficiently 

 rooted for being removed to plant out. 



These trees have great merit for ornamenting 

 shrubbery plantations, in assemblage with 

 others of similar growth*., being handsome, 

 straight-growing trees, with fine heads, as well 

 as adapted for planting, detached as single ob- 

 jects, in spacious short grass openings, in which 

 they appear very ornamental, perfuming the air 

 all round in sunmier. 



Thcv succeed in any common soil and situa- 

 tion, and endure the severest cold without injury. 

 They are usually l<ept in the nurseries for sale.

LIKIODENDRUM, a genus containing a 

 plant of the hardy deciduous ornamental tree 

 kind. 



It belongs to the class and order Pohjandria 

 T^olygynia, and ranks in the natural order of 

 Coudunatce. 



The characters are ; that the calyx is a proper 

 two-leaved involucre: the leaflets triangular, flat, 

 deciduous : perianthium three-leaved : leaflets 

 oblong, concave, spreading, petal-form, deci- 

 duous : the corolla six-petalled, bell-shaped ; 

 petals spatulate, obtuse, channelled at the base; 

 the three exterior deciduous : the stamina have 

 numerous filaments, shorter than the corolla, 

 linear, inserted into the receptacle of the fruc- 

 tification ; anthers linear, growing longitudi- 

 nully to the sides of the filament : the pistillum 

 has numerous germs, disjiosed into a cone : 

 style none : stigma to each globose : there is 

 no pericarpium : seeds imbricated into a body 

 resembling a strobile : the seeds numerous, 

 ending in a lanceolate scale, emitting an 

 acute angle towards the base of the scale from 

 the inner side, compressed at the base, acute. 



The species cultivated is : L. tulipijh-a, Com- 

 mon Tulip-Tree. 



It has the young shoots covered with a 

 smooth purplish bark ; they are garnished with 

 large leaves, whose foot-stalks are four inches 

 long ; they are ranged alternate ; the leaves are 

 of a singular form, being divided into three 

 lobes ; the middle lobe is blunt and hollowed at 

 the point, appearing as if it had been cut with 

 scissars ; the two side lobes are rounded, and 

 end in blunt points : the leaves are from four 

 to five inches broad near their base, and about 

 four inches long from the foot-stalk to the 

 point, having a strong midrib, « hich is formed 

 by the prolongation of the foot-stalk : from the 

 midrib run many transverse veins to the 

 borders, which ramify into several smaller: 

 the upper surface of the leaves is smooth, and 

 of a lucid green, the under is of a pale oreen : 

 the flowers are produced at the end of the 

 branches ; they are composed of six petals, 

 three without, and three within, which form a 

 sort of bell-shaped flower, whence the luuiie : 

 these petals are marked with green, \e!low, 

 and red spots, making a fine appearance w hen 

 the trees are well charged with flowers: the 

 time of flowering is in July ; and when the 

 flowers drop, the germ swells, and forms a kind 

 of cone, which does not ripen in this climate. 

 It is a native of North America. 



It grows so large as to be a tree of the first 

 magnitude in its native situation, and is gene- 

 rally known by the title of pojdar : of la^e
