A tree, usually sixty to seventy, or sometimes one hundred and twenty to one hundred and thirty 

 feet in height, with a taU slender trunk three or four feet in diameter, and slender, often pendulous 

 branches, the ultimate divisions spreading nearly at right angles. The bark of the trunk is about an 

 inch thick, furrowed, the light brown surface broken into small thin scales. The bark of the branchlets 

 is smooth, light gray, faintly tinged with red, and marked with numerous oblong dark wart-hke excres- 

 cences; it becomes darker in the second year, and in the third is dark gray or brown and conspicuously 

 rugose. ^ The dark red winter-buds are stout, ovate, and pointed. The leaves are obhquely cordate 

 or sometimes ahnost truncate at the base, the acuminate apex often contracted mto a long slender point, 

 sharply and deeply glandular-serrate, glabrous, with the exception of the tufts of rusty brown hairs on 

 the lower surface in the axils of the principal veins ; they are thick and firm, lustrous on the upper sui- 

 face, five or six inches long, three or four inches broad, and are borne on slender petioles an inch and 

 a half or two inches long. They turn pale yellow in the autumn before faUing. The pedunculate bract 

 IS fom- or five mches long, an inch or an inch and a half broad, rounded or pointed at the apex, and 

 tapermg usually to a short-stalked base. The cyme of flowers is produced on a peduncle three and a 

 half to four mches long. The flowers, borne on slender slightly angled pedicels, open during the first 

 weeks of July from buds slightly angled by the reduplicate margins of the sepals, and densely coated 

 with wlute tomentum. The sepals are densely hairy at maturity on the inner, and minutely pubescent 

 on the outer surface. The ovary is hairy, and the fruit, tipped with the remnants of the style, is densely 

 covered with short rufous tomentum. The seed is nearly a qi^arter of an inch long. 



The northern limits of Tilia Americana are in northern New Brunswick j thence it extends west 

 to the eastern shore of Lake Superior, and then northward and westward to the southern shore of Lake 

 Wmnipeg and to the valley of the Assiniboine Eiver.^ It extends southward through the Atlantic
