| + | Lippia nodiflora, Michx. (Verbena nodiflora, Linn. Zapania nodifldra, Lam. Phyla nodifldra, Greene). Sometimes described as annual, but probably perennial, extensively creeping and rooting but with ascending branches, greenish or grayish: lvs. opposite, cuncate-spatulate to oblanceolate, nearly or quite sessile, tapering to a long entire base, serrate above the middle: heads ovoid and becoming nearly cylindrical, on filiform peduncles that exceed the lvs., the bracts obovate or irregularly cuneate, acuminate and sometimes mucronate; fls. rose-purple to nearly white, the corolla short; calyx thin in texture, equaling corolla, unevenly cleft on the two sides, the teeth lanceolate; bracts of fl.-head about as long as corolla-tube, with glabrous or nearly glabrous hyaline margins. Sandy soil, Ga., south (in the tropics widely distributed); in Calif, prominent on river banks, and, according to Jepson, esteemed for holding levees against erosion. |
| Lippia canescens, Kunth (L. repens, Hort., not Spreng.). St. somewhat woody at the base and rooting, widely spreading, canescent: lvs. small, from spatulate to oblong and lanceolate, attenuate to petiole, acute, dentate toward apex: heads ovoid or subcylindrical; the bracts herbaceous, oboyate-cuneate, acuminate, narrowly membranous-margined, imbricated; corolla conspicuously larger than in related species, rosy, with a yellow throat; calyx short 2-toothed, with villous keels; bracts of fl.-head shorter than the corolla-tube, with villous margins. S. Amer., in dry, grassy places. —This plant, under the name of L. repens, is exceedingly useful in Calif, as a ground-cover, especially to persons who do not care to go to the expense of keeping up a grass-lawn. The tops sometimes freeze in the region of San Francisco, but the plants come on well in spring. By keeping the area mown, the weeds are not very troublesome. | | Lippia canescens, Kunth (L. repens, Hort., not Spreng.).
