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.
Range:
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.
