The habitat of the plant is woods. The leaves are convolute, heart-shaped, oblong to ovate, on hollow stalks, angular, rfearly flat above. The flowerheads are purple, racemose, hardly stalked, round, ovate, contracted at the mouth in fruit, slightly webbed, in threes, close, at the end of branches, when young ovate, prolonged, not umbilicate. The phyllaries are ascending, and equal or exceed the florets, being awllike, the inner row lance-shaped, shorter. The upper part of the florets is more or less cylindrical, as long as the lower part. The plant is 2-4 ft. high, flowering in August, and is a biennial.
The habitat of this plant is woods in the north, mountain woods, and shady places. The habit is the rosette habit. The plant is erect, the stem purple below, slender, hairy or smooth. The lower leaves are oblong, spoon-shaped, narrowed into a foot-stalk, the upper stalkless, half-clasping, linear, oblong. The flowerheads are few, the florets yellow, in a corymb, the flower-stalk glandular, hairy. The involucral bracts are tipped with glands, lance-shaped, narrow, the involucre nearly cylindrical, the outer bracts close, short, as long as the pappus. The fruit is smooth, striate, with many ribs, narrowed above and below, as long as the White silky pappus. The plant is 2-3 ft. in height, flowering in July and August, and is a herbaceous perennial.
The habitat of this plant is moist mountain meadows, moist grassy ground, shady places, woods, and copses. The habit is erect, the stem being smooth, unbranched, angular, with many leaves, the radical ones egg-shaped, oblong, tapered, lance-shaped, the stem-leaves oval, large, heart-shaped, clasping, the leaf-stalks slender.
The flowers are yellow, the involucral bracts glandular, with black hairs. The fruit is cylindrical, not beaked, the pappus stiff, brittle, dirty white or brown, 10-ribbed. The plant is 2 ft. in height and is in flower between July and September, being a herbaceous perennial.

The styles are brown. The plant is 9-15 inches in height, flowering in June and July, and is a herbaceous perennial.
The habitat of this plant is woods. The stem is tall, wavy, purplish, stiffly hairy below and above, downy above. The radical leaves are 3-4, the outer soon fading, oval, toothed or nearly entire, the inner oval to oblong, lance-shaped, the innermost acute, shortly toothed. The stem-leaves are distant, the lower large, egg-shaped to lance-shaped, long-pointed, deeply divided nearly to the base, toothed below, with irregular lobes, stiffly hairy, stellately downy. The panicle is simple, the lower branches distant, the upper close, longer than the acladium. The flower-stalks are woolly-felted, hairy, glandular. The involucre is slender, rounded below. The phyllaries are linear to lance-shaped, the inner with a green border, with long, naked, points, woolly-felted at the base, glandular, sparsely hairy. The styles are yellowish or dingy.
Hieracium tridentatum, Fr., pro parte. - The habitat of this plant is hedgebanks and borders of woods. The stem is purplish, stiffly hairy, woolly-felted, nearly smooth above.

The lower stem-leaves are shortly stalked, lance-shaped, toothed, woolly-felted, stiffly hairy below, fringed with hairs on the border. The panicle is a compound corymb, the branches racemose, slender, erect to spreading, the upper close to spreading. The flower-stalks are arching, stiffly hairy, glandular. The heads are small, dark green, egg-shaped below. The phyllaries are dark green, linear, triangular to lance-shaped, the inner narrow, pale-tipped, woolly-felted, senescent, glandular, hairy.
