"Flowers in few-flowered, open panicles; corolla inconspicuously 

 spotted. Fruit stout. Leaves caudate acuminate. 



"A tree in the forest occasionally 120 feet in height, with a tall, 

 straight trunk, rarely four and a half feet in diameter, and a narrow, 

 round-tipped crown of slender branches; usually smaller, although often 

 a hundred feet high, and when grown in open situations rarely more than 

 fifty feet in height, with a short trunk and a broad head of spreading 

 branches. The bark of the trunk is three-quarters of an inch or sometimes 

 nearly an inch thick, brown tinged with red, and broken on the surface 

 with thick scales. The branchlets are stout, and when they first appear 

 are light green, often tinged with purple, and covered with scattered pale 

 hairs; during the first winter they are light orange color or reddish brown, 

 covered with a slight bloom, and marked with many pale, conspicuous 

 lenticels, and with the elevated oval leaf-scars, which are a quarter of an 

 inch long and display a circular row of large fibro-vascular bundle scars; 

 in their second and third years the branches grow darker and the leaf-scars 

 and lenticels nearly disappear. The end of the branch dies in the autumn 

 without forming a terminal bud, and during the winter appears as an 

 elevated circular scar close to the upper axillary bud. The buds are 

 minute, globose, partly immersed in the bark, and covered with loosely im- 

 bricated chestnut-brown ovate scales, keeled on the back and slightly 

 apiculate at the apex; those of the inner ranks are accrescent and at 

 maturity are foliaceous, obovate, acute, gradually narrowed below a sessile 

 base, many nerved, with dark veins pubescent on the lower surface, and 

 sometimes nearly two and a half inches long and three-quarters of an 

 inch broad. The leaves are opposite or in threes, oval, long-pointed, cor- 

 date at the base, and usually entire or funished with one or two lateral 

 teeth ; when they unfold they are pilose on the upper surface and covered 

 on the lower and on the petioles with pale or rufous tomentum, which soon 

 disappears, and at maturity they are thick and firm, dark green above and 

 pale and covered with soft pubescence below, especially along the stout 

 midribs, and the principal veins marked in their axils with large clusters 

 of dark glands. They are ten or twelve inches long, seven or eight inches 

 broad, and are borne on stout terete petioles four to six inches in length. 

 They turn black and fall after the first severe frost of the autumn. The 

 flowers, which appear late in May or early in June, are borne on slender 

 purple pedicels, furnished near the middle with one or three branchlets, 

 and are produced in open, few-flowered panicles five or six inches long and 

 broad, with green or purple branches marked with orange-colored lenticels, 

 the lowest being often developed from the axils of small leaves. The 

 calyx is purple and divided at the base into two ovate pointed apiculate 

 divisions. The corolla is white, with a broad conical oblique tube nearly
