Epilobium minutum

Epilobium minutum is a species of flowering plant, known by the common names little willowherb, chaparral willowherb and desert willowherb, in the family Onagraceae.^[1][2][3] It is also called "smallflower willowherb" in reference to its relatively small size. However that name, in particular the British English variant "small-flowered willowherb", typically refers to Epilobium parviflorum.

This annual wildflower is native to western North America from British Columbia and Alberta to California and Arizona. This is a plant of fields and meadows, including vernal pools, and it is one of the first flowers to spring up in areas recently cleared by wildfire.

Epilobium minutum is a small, spindly plant with thin, branching stems approaching a maximum of 40 centimeters (16 in) in height. The sparse leaves are oval-shaped and 1 or 2 centimeters (0.39 or 0.79 in) long. The stems are topped with few tiny white to light purple flowers with notched petals each a few millimeters long. The fruit is a capsule 1 or 2 centimeters (0.39 or 0.79 in) in length. It is a much smaller plant than most members of the genus, referenced by both the specific name minutum as well as some of its common names.
