Vesper multinervatus

provided by wikipedia EN

Vesper multinervatus, synonym Cymopterus multinervatus, is a species of flowering plant in the carrot family Apiaceae,[2] known by the common name purplenerve springparsley. It is a perennial herb native to the southwestern United States, including the desert regions. It is stemless, producing leaves and inflorescence at ground level from a taproot. The leaves are erect on petioles of a few centimeters in length, with a fleshy blade dissected into waxy multilobed leaflets. The inflorescence arises on a stout purple or greenish peduncle up to about 14 centimeters tall. At the top is a rounded cluster of purple flowers sheathed in purple-veined bracts.
