176 FOUNDATIONS OF BOTANY 



II. FORSYTHIA, Vahl. 



Shrubs. Leaves opposite or in threes, appearing later than 

 the flowers, serrate. Calyx very short, deciduous. Corolla 

 yellow, bell-shaped, its lobes long and slender. Stamens 

 inserted on the base of the corolla-tube. Pod 2-celled, many- 

 seeded. 



1. F. viridissima, Lindl. A hardy shrub, with branches erect or 

 nearly so. Leaves all simple, lance-oblong. Calyx-lobes half as long 

 as the tube of the corolla. Lobes of the corolla spreading, narrow- 

 oblong, style equal in length to the tube of the corolla. Cultivated 

 from Asia. 



2. F. suspensa, Vahl. A hardy shrub, with drooping branches. 

 Leaves broadly ovate, often some of them with 3 leaflets, the lateral 

 leaflets small. Lobes of the corolla longer, broader, and more spread- 

 ing than in No. 1. Style shorter than the tube of the corolla. Culti- 

 vated from Asia, less common than No. 1, often trained over porches 

 and arbors. 



HI. SYRINGA, L. 



Tall shrubs, forking frequently, from the failure of the 

 terminal buds on most branches. Leaves simple, entire. 

 Flowers in close, compound panicles. Calyx 4-toothed. 

 Corolla salver-shaped, the tube long, the limb 4-lobed. Pod 

 dry, flattened at right angles to the partition, 4-seeded. 



1. S. vulgaris, L. COMMON LILAC. A strong-growing, hardy bush. 

 Leaves ovate, somewhat heart-shaped. Flowers sweet-scented, in 

 very close, large clusters, lilac or white. Corolla-lobes concave. 

 Very commonly cultivated from Eastern Europe. 



2. S. persica, L. PERSIAN LILAC. A more slender and less 

 branched shrub than No. 1. Leaves lance-ovate, somewhat nar- 

 rowed or tapering at the base. Flowers in rather loose clusters, not 

 very sweet-scented, pale lilac or white. Corolla-lobes ovate, some- 

 what bent inward. Pods linear. Cultivated from Western Asia, 

 less common than No. 1. 



IV. CHIONANTHUS, L. 



Shrubs or small trees. Leaves simple, opposite, entire, 

 petioled, deciduous. Flowers in panicles borne on wood of 

 the previous season. Calyx small, 4-cleft, persistent. Corolla
