Banks of the Ohio and Mississippi, Pursh ; near Macon, Georgia, Dr. 

 Loomis! — Leaves 4-8 inches in diameter, very oblique and naore or less cor- 

 date, with a short abrupt acumination, someAvhat shining above ; the veins 

 on the under surlace veryconspicuousin contrast with the white pubescence. 

 Cyme few-flowered, loose. Style longer than the petals. 



3. T. alba (Michx.) : leaves glabrous above, whitish-pubescent beneath ; 

 the veins pale ; serratures mucronately acuminate ; petals emarginate ; sta- 

 minodia spatulate, entire ; style nearly glabrous at the base.— Mc/i^./ sylv.

Woods, particularly along rivers, Pennsylvania to Maryland, and in the 

 Western States, Michau.v., f. Santee River, South Carolina, Dr. Godine! 

 —Leaves 3-4 inches in diameter with a short abrupt acumination, cordate, 

 somewhat unequal at the base ; the under surface rather thinly pubescent, 

 very pale, but scarcely white. Staminodia | the length of the petals. Fila- 

 ments slightly pentadelphous. 



4. T. puhescens (Ait.): leaves of nearly the same color on both surfaces, 

 nearly gkbrous above, pubescent beneath ; serratures slightly mucronate ; pe- 

 tals crenulate at the summit ; style hairy at the base.—" Vent. I. c. p. 10. t.

Fertile soils, along the sea-coast of Carolina, to Florida'. Mich an x, f. 

 Elliott, Baldwin! Kentucky, 5fAoH .' Texas, Drummond .' June.— A large 

 tree. Leaves 3-4 inches in diameter, the under surface when young rather 

 paler than the upper, but at length of nearly the same color ; serratures broad 

 and short. — There is great uncertainty respecting the synonymy of the last 

 three species, owing to the imperfect manner in which they are described by 

 most preceding authors. Indeed nearly aU the characters which have been 

 employed for distinguishing them are either inconstant or are common to 

 them all. A careful examination of the flowers in the living plants may af- 

 ford more certain marks of discrimination. 



Order XL. MELIACE^. Juss. 



Sepals 3-5, distinct or more or less united, imbricated in aestivation. 

 Petals hypogynous, as many as, and longer than the sepals, alter- 

 nate with them, often connivent or cohering at the base with each 

 other or with the stamen-tube: sestivation valvate or imbricated. 

 Stamens usually twice the number of the petals : filaments united into 

 a tube, inserted outside the hypogynous often discoid torus : anthers 

 sessile within the orifice of the tube. Ovary with usually the same 

 number of cells as petals, each cell containing 1-2 ovules : styles and 

 stigmas commonly united into one. Fruit drupaceous, baccate, or 

 capsular, with as many cells as stigmas, or by abortion l-celled ; 

 when dehiscent, loculicidal. Seeds mostly anatropous, sometimes aril- 

 led, never winged or flat : albumen thin and fleshy, or none. — Trees or 

 shrubs. Leaves alternate, without stipules, simple or compound.
