About Hieracium argutum Nutt.
Hieracium argutum Nutt. is a perennial herb that grows a mostly erect stem. Its lower stem is very hairy, and the hairiness decreases to nearly hairless toward the tip of the stem. This plant reaches between 60 centimeters and one meter in height. Its deeply toothed leaves are covered in long hairs. The largest leaves, which grow at the base of the stem, can reach 16 centimeters long. Shorter leaves may appear on the lower portion of the stem, and the upper portion holds few or no leaves. The inflorescence forms a wide, open cluster that holds many flower heads, each reaching up to about one centimeter wide. Each flower head is lined with hairy, often glandular phyllaries. It is filled with many yellow ray florets and contains no disc florets. Its fruit is a small, dark cylindrical achene, topped with a pappus made of brown bristles.
