Characteristics:

Also known as small-flowered Nemophila, Wood's nemophila is a small, easy to miss wildflower with prostrate or procumbent stems from 5-15 cm long. The leaves are mostly opposite, ovate, and pinnately 5-7 parted with the blade longer than the leaf stem. The leaf blades range from 1-3.5 cm long and .8-2.5 cm wide and the lower lobes are often as large or larger than the terminal lobe. The blades are sparsely covered with appressed hairs.

The flowers as the species name parviflora indicate are small, ranging from 2-5 mm wide. The pedicels measure 2-15 mm long while in flower, and up to 3 cm long in fruit. The flowers are short, tubular and 5-petaled with white or lavender coloration. The corolla is about equal to or slightly longer than the bristle-edged calyx lobes and measures 3-3.5 mm long.


Varieties of Wood's Nemophila:

variety austinae: The leaves are all opposite on the stems, and they are firmer, smaller in size, and less deeply cleft (See photo at right.). Found at moderate and higher elevations on the east side of the Cascades.

variety parviflora: The leaves are usually opposite on the stems, but some of the upper leaves may be alternate. The leaves tend to be thin and deeply cleft, with the lobes often toothed or narrowed at their bases. Found at lower altitudes on the west side of the Cascades.


Habitat:

Wood's nemophila may be found on wooded slopes or other shady places from the valleys to moderate elevations in the mountains.


Range:

Wood's nemophila may be found from southern British Columbia south to California and east to central Idaho and northern Utah.
