Limestone Wild Petunia
Ruellia strepens /Acanthus Family
One difference between this plant and the previous one is the location of the nectar guides. This one has the guides on the side, as if the flower grows sideways! This plant just about drove me nuts trying to figure out its' species. My 3-inch thick "big scientific words" botanical manual describes this plant as having flowers "in subsessile or pedunculate, axillary glomerules from upper nodes" and having "glandular-pubescent, lanceolate calyx lobes." No wonder it drove me nuts!!! I took botany as an elective at UT Knoxville 30 years ago when algae and some protozoa were still considered as being in the Plant Kingdom! Things have changed a lot since then! I didn't have to learn all those difficult botanical terms in Botany 101! I found this plant blooming at the Haw Ridge Greenway in Oak Ridge in late May.
