Krigia biflora - Two-flower Cynthia, Twoflower Dwarfdandelion, Orange Dwarf-dandelion. Krigia is a small genus of about 7 species endemic to North America. Most species are only in the eastern part of the continent, east of the Great Plains, except for this plant, Krigia biflora. One of the two varieties, var. viridis is found in Colorado, Arizona, and New Mexico, and is a smaller plant than the variety shown here, Krigia biflora var. biflora. Krigia biflora var. biflora is also found in most of the eastern half of the continent. The Krigia flowers are similar and closely related to those in the Hieracium genus.

Krigia biflora can grow to over 2 feet tall, although it is usually much shorter (K. biflora var. viridis is rarely more than a foot tall.) The vaguely toothed or entire leaves are primarily basal, on somewhat winged petioles. There are usually at least 1 and up to 4 cauline (stem) leaves, which are sessile to clasping, and much reduced in size in the upper plant. There are usually 2 to 6 peduncles arising from the upper bract-like leaves.
