Proboscidea parviflora is a species of flowering plant in the family Martyniaceae known by the common names doubleclaw and red devil's-claw. It is native to the desert southwest of the United States and northern Mexico, where it grows in sandy, dry, and disturbed habitat and blooms during the hot summer. This is an annual herb growing from a taproot and producing sprawling, spreading stems. The leaves have rounded, oval, or roughly triangular blades up to 15 cm long which have smooth edges or faint lobes or teeth. The inflorescence is an array of several showy bell-shaped flowers with five lobes flaring several centimeters wide. The flower is white to pink or purple, sometimes with mottling or lines of spots in the throat, and often a purple blotch on the upper lip. A yellow nectar guide extends along the lower lip. The fruit is a large seed pod many centimeters long, a cylindrical body tapering into a very long, thin, curving tail. As the fruit dries the tail cracks open and splits into two hooked, claw-like halves. The young fruits and seeds were used for food and the dark-colored hardened dry fruits were used in basketry by local Native Americans.Ethnobotany dry fruits Proboscidea parviflora - [[MHNT]]

How to read this: each dot is one detection of this species' DNA in an environmental sample. The confidence meter weighs how many independent studies and places back up the signal — one detection in one study is a hint; many across several studies is solid. Records dated before 2008 (when eDNA methods began) are treated as likely mislabeled and left off the map.
