|}}Pyrrhopappus carolinianus, commonly called Carolina desert-chicory,^[1] or Texas dandelion is in the Asteraceae or Compositae family in the genus Pyrrhopappus, native throughout Eastern and South Eastern United States. It is a weedy annual found in mostly open grasslands and wet roadsides. P. carolinianus can bloom from spring to frost with the heads facing the sun throughout the day. ”^[2]

Identification

Pyrrhopappus carolinianus can have more than one erect, flowering stem that can grow up to 50 cm. in length. The leaves are deeply lobed 5-15 cm. long. The smaller upper leaves are slightly indented. The yellow flowers can be up to 3.75 cm. in width. Because it is in the asteraceae family, it has rays and disc flowers, both of which are yellow.

Pollination

The oligolectic bee, Hemihalictus spp., have been found to be the pollinators for the Carolina desert-chicory. ”^[2]
