Forsythia intermedia, Zabel (F. suspensa x F. viridissima,). Shrub, with slender, erect or arching branches: lvs. oblong to ovate-lanceolate, sometimes 3-lobed or ternate, usually coarsely serrate, 3-4 in. long: fls. almost like those of F. suspensa var. Fortunei. Gt. 1885:1182; 40, p. 397. Gn.W. 22:181. Var. vitellina, Koehne (F. vitellina, Koehne). With upright or spreading branches: fls. deep yellow, little over 1 in. long. Gt. 55, pp. 227, 228. Var. spectabilis, Spaeth (F. spectdbilis, Koehne). Upright with spreading and somewhat arching branches: fls. somewhat paler than of the preceding, 1 1/3 in. long, often 5-6-merous. Gt. 55, p. 229. G. 35: 255. Var. densiflora. Koehne (F. densiflora, Koehne). Upright shrub with divaricately spreading and slender arching branches: fls. crowded at the base of the branches, rather pale with flat slightly recurved corolla-lobes. Gt. 55, pp. 230, 231. Var. primulina, Rehd. Upright shrub, with spreading and arching branches: fls. crowded at the base of the branches, pale yellow; lobes of the corolla revolute at the margin.—F. intermedia is often confounded with forms of F. suspensa. In foliage it resembles much the following, which has the lvs. narrower, always simple, usually serrate only above the middle, with smaller teeth. It is as hardy as F. suspensa and very floriferous.
