 in height with a trunk 6-15 inches in diameter, farther west in the Ohio 

 basia reaching a height of 100 feet with a trunk diameter of 4 feet. In 

 the open the bole is short and bears a broad, spreading crown. Trees in 

 the forest possess tail, straight trunks and reduced cro^vTis. 



Leaves — - Opposite or 3 at a node, broadly ovate, 8-14 inches long, 6-8 inches 

 wide, acuminate at the apex, rounded or cordate at the base, entire or 

 with 2-3 lateral teeth, at maturity thick, firm, dark green above, paler 

 and soft pubescent below, borne on stout, terete, pubescent petioles 4-6 

 inches in length. 



Flowers — Appearing in June and early July after the leaves, perfect, showy, 

 borne on slender, purple pedicels in terminal, open, few-flowered panicles 

 5-6 inches long. Calyx purple about y2 of an inch long, divided to the 

 base into 2 ovate, apiculate divisions. Corolla white, spotted A^-ith purple, 

 2-21/^ inches long, A\'ith broad, campanulate, flat tube and spreading, 

 5-lobed limb. Tube marked on the inner surface of the lower side A\'ith 2 

 rows of yeUow blotches following 2 parallel ridges. Stamens 2, slightly 

 exserted, ■v\'ith flattened, twisted filaments and oblong anthers borne vis- 

 a-vis on either side of the stigma. Pistil consisting of a sessile, ovoid, 

 2-celled ovary abruptly contracted above into a slender glabrous style 

 bearing 2 stigmatic lobes at the apex. 



Fruit — A linear, subterete, dark brown capsule 8-20 inches long, %-% of 

 an inch thick at the center and tapering toward each end. The capsules 

 are borne in thick-stemmed persistent panicles and remain closed and

 valves before falling to loose the seeds. Seeds numerous, oblong, com- 

 pressed, ringed. The -w-ings entirely surround the seed and are produced 

 longitudinally into fringed ends.

 mth a slight bloom, reddish or yellowish bro-nni, marked by numerous, 

 conspicuous lenticels and raised, circular leaf-scars, usually winter-kiUing 

 at the tip in New York State. Terminal bud absent. " Lateral buds 

 minute, hemispherical, chestnut-bro^\Ti, imbedded in the bark. Bud-scales 

 loosely imbricated. Pith large, white, homogeneous or chambered at the 

 nodes. Mature bark, thin, reddish or grayish brown, broken by shallow 

 fissures into longitudinal, flat ridges. 



Habitat — Prefers rich, moist soils along stream courses and on bottom-lands. 

 In New York State it occasionally becomes naturalized about door-yards 

 and abandoned homes.
