Hairy Purslane Speedwell, Purslane Speedwell: Veronica peregrina ssp. xalapensis (Synonyms: Veronica peregrina var. xalapensis, Veronica sherwoodii, Veronica xalapensis) Characteristics:

Purslane speedwell is perennial, fibrous-rooted plant with erect or spreading stems from 5-30 cm high. The stems are either simple, or often branched below. The herbage often consists (as seen in the photos) of short, often gland-tipped hairs on the stems, leaves, and sepals. The leaves are generally opposite on the stems and are oblong, linear-oblong, or oblanceolate in shape, measuring 0.5-3 cm long and from 1-9 mm wide. The leaf margins vary from entire to irregularly toothed.

The lax inflorescence is terminal. The leaf-like bracts alternate up the elongated inflorescence and subtend a single subsessile flower. The corollas are white and only about 2 mm wide. The fruits are heart-shaped and abot 3-4 mm high.

Purslane speedwell is the only wetland member of the genus Veronica to have white flowers.


Habitat:

Purslane speedwell is a species of wet swales, meadows, streambanks, and other wet places.

Purslane speedwell is a wetland species common across much of North and South America and introduced to Europe.
