Characteristics:

Chickweed monkey flower is a petite, annual monkey flower. Its stems range from simple to freely branched, and arise from 4-30 cm in height. The leaves range from 0.5-2 cm long and are obtuse to rounded in shape. The margins are lightly to coarsely toothed, and the blade is 3-5 nerved.

The flowers have long pedicels and the calyx is mostly smooth (occasionally lightly glandular). The 3 upper calyx lobes are short with sharper points while the 2 lower lobes are longer with rounded tips. The tubular corolla is yellow, 8-14 mm long, with a large reddish-brown spot at the base of the lower lip. The corolla is 2-lipped with the middle lobe of the lower lip larger than the others and flexed downwards.


Habitat:

Chickweed monkey flower may be found on vernally moist, moss-covered banks and cliffs.

Chickweed monkey flower may be found from southern British Columbia south through and west of the Cascade Mts. to northern California.

In the Columbia River Gorge, it may be found between the elevations of 100'-2400' from east of Troutdale, OR as far east as Wishram, WA.
