Flaxleaf False Foxglove is a native herbaceous perennial in the Broomrape family (Orobanchaceae). It is native to the southern third of Alabama. Flaxleaf False Foxglove occurs in Pine Flatwoods, in swales in pine savannahs, in bogs, and in roadside ditches. It is a perennial with an elongated rhizome. Stems are erect, unbranched or branched above the middle with stiff erect branches, green in color, glabrous, and round in cross section. Leaves are opposite, sessile, linear in outline, glabrous, and entire. The leaves are appressed to the stem. Flowers are produced in terminal racemes. The pedicel is erect. The calyx is 5 lobed with the lobes shorter than the tube. The corolla is pink-purple in color, with numerous purple spots, but lacking yellow lines. The corolla is 5 lobed. The fruit is a capsule. Flaxleaf False Foxglove is hemiparasitic. Seedlings must establish a connection to the roots of pines for continued growth. Flaxleaf False Foxglove is listed as an S2 species in Alabama (typically 6 to 20 occurrences, few remaining individuals or factors demonstrably making it very vulnerable in the state) and globally as a G4 species (imperiled globally because of rarity or very vulnerable to extinction throughout its range because of other factors).—A.
