Hieracium Serratifrons, Almq

This species is not found in the typical state, but numerous varieties are met with in this country. The stem is stiffly hairy below, woolly-felted, glandular above. The radical leaves are like those of H. silvaticum, the outer abruptly narrowed or heart-shaped below, the others running down the stalk, toothed, stiffly hairy below. The stem-leaf is stalked, linear, or egg-shaped, lance-shaped, acute. The panicle is more or less composite, umbelled above. The heads are dark. The phyllaries are rather broad, shorter, and blunt, or longer and acute, glandular, hairy, woolly-felted, and senescent. The styles are yellow or dull.

The stem-leaves are small, high on the stem, linear, bractlike, woolly-felted, or when low large, lance-shaped, with a long, narrow point, nearly hairless, stalked, clasping. The panicle is a forked corymb, the upper branches close, exceeding the acladium. The flower-stalks are short, straight, woolly-felted, glandular. The heads are 6-8, with a blunt base. The phyllaries are bent in in bud, dark, broad, short, the outer triangular, elongate, the inner lance-shaped, acute, woolly-felted, glandular. The styles are brownish-olive. The ligule tips are smooth or downy. The margins of the receptacle pits are cut, toothed, the teeth awllike or bristle-like. The plant is 12-18 in., flowering in July, and is a herbaceous perennial.

Hieracium rubiginosum., F. J. Hanb. - The habitat of this plant is limestone scars. The stem is simple or branched, robust, purplish-red (hence rubiginosum), hairy below, woolly-felted, glandular above. The radical leaves are thick, numerous, large, broadly egg-shaped, dull deep green, purple-tinged, acute, lance-shaped, toothed, the base wedge-shaped, stiffly hairy on the paler under surface, and a little on the upper, the margins toothed. The stem-leaves, 1-3, are stalkless, egg-shaped, long, narrow-pointed, lance-shaped, sharply toothed. The panicle is a close, falsely forked corymb, the branches exceeding the acladium. The heads, 4-15, are cylindrical, blunt. The flower-stalks are woolly-felted, hairy. The phyllaries meet together in bud, and are broad, blunt, the inner narrowed, acute, with a pale border, woolly-felted, stiffly hairy, glandular. The ligules are golden, the tips are stiffly hairy at the back. The styles are yellow. The margins of the receptacle pits are raised, toothed, and lacini-ate.
