| Ipomoea hederacea, Jacq. (I. nil, Roth. I. scabra, Forsk. and Hort.). St. twining or climbing, 2-8 ft.: lvs. 2-5 in. long, ovate-cordate, the lobes ovate to ovate- lanceolate, entire, or the lateral lobes repand or denticulate; the middle lobe narrowed at the base: peduncle 1-3-fld., mostly shorter than the petiole; corolla funnel- form, the tube usually white, the limb light blue, purple or rose, and in various combinations of these colors; sepals hairy, lanceolate, with long and often recurved tips. July-Oct. Widely naturalized from Trop. Amer. in fields and waste places, Pa. to Fla., west to Neb. and Mex. Perhaps native in the South. B.R. 85 and 276 (as I. caerulea). B.M. 188 (as Convolvulus nil). Gn. 27, p. 473.—This species shows great variation in the form of its lvs., both on the same plant and on different plants. In some forms formerly known as I. nil, the lvs. are nearly entire; in others they are very deeply lobed. Next to I. purpurea, this is now the most popular morning-glory in cult., and the intro. of the improved Japanese strains will extend its usefulness. Before the appearance of these oriental varieties in occidental gardens, the species had already varied into many distinct horticultural varieties; as var. limbata, (I. limbata, Hort.), with the corolla violet- purple, edged with white. B.M. 5720 (as Pharbitis Nil). Gn. 29, p. 32. var. marmorata caelestina, large fls., marbled and striped with light blue. Gt. 44, p.592. var. marmorata rosea, fls. marbled with rose, t. 44, p. 76. var. foliis marmoratis, lvs. marked with yellow, limb of corolla rose-color. var. grandiflora, large blue fls. var. ferrandiana, similar to var. grandiflora. Aside from these strains, the following named varieties of Japanese ipomoeas are offered: Antigone, lvs. variegated: fls. blue, with pink throat. Aglaia, lvs. variegated: fls. crimson, with white throat. Aseria, fls. dull copper-red. Ceres, like Aglaia, but fls. edged with white. Euphrosyne, lvs. variegated: fls. pure white, with pink throat. Princess, fls. spotted with carmine. Gt. 47, p. 133. A form with foliage dotted with white is shown in I.H. 43, p. 75. The various strains give fls. which are diversely scalloped, ruffled, fringed, double, and show a wonderful range of coloring. | | Ipomoea hederacea, Jacq. (I. nil, Roth.
