Wedgeleaf Thoroughwort is a good name, as the lower leaves are indeed wider in the outer half. Mid-stem and upper leaves are often just elliptical in shape. Leaves are often somewhat twisted. Leaves of Mohr's Thoroughwort (E. mohrii) may also be wedge-shaped, but that species inhabits moist to wet soils. The very similar E. linearifolium has narrower leaves.
