 except at the South. Flowers fragrant.

J. odoratissimum, Linn. Common Sweet Yellow J., from Madeira ; 

 smooth, twining ; leaflets 3 or 6, ovate ; peduncles terminal, few- 

 flowered. 



J. hum He, Linn, (or J. revoltjtum), from S. Asia; not twining, has 

 mostly 3-7 leaflets, and more numerous and fragrant flowers, 1$' wide. 



# * Flowers yellow; leaves opposite, but usually falling before the flowers 



appear. 



J. nudiflbrum, Lindl. Branches green and angled ; leaves small and 

 ternate, falling in autumn, after which the yellow scentless flowers 

 appear. China. 



* * * Flowers white ; leaves opposite. 



J. officinale, Linn. Common White J. From the East ; has striate- 

 angled branches scarcely twining, about 7 oblong or lance-ovate leaflets, 

 a terminal cyme of very fragrant flowers, and calyx teeth slender. 



J. grandifldrum, Linn. From India ; has 7 or 9 oval leaflets, the upper- 

 most confluent, larger and fewer flowers than the foregoing, reddish 

 outside. 



J. Sdmbac, Sol. From tropical India; scarcely climbing, pubescent; 

 leaves simple, ovate, or heart-shaped ; flowers in small close clusters ; 

 calyx teeth about 8, slender, the rounded lobes of the corolla as many ; 

 flowers simple or double, very fragrant, especially at evening. 



2. PORSTTHIA. (Named for W. A. Forsyth, an English botanist.) 

 Ornamental shrubs, from China and Japan, with flowers from separate 

 lateral buds, preceding the serrate leaves, in early spring. 



F. viridissima, Lindl. A vigorous shrub, with strong and mostly erect 

 yellowish angled green branches, covered in early spring with abundant 

 showy yellow flowers ; calyx lobes half the length of the corolla tube ; 

 lobes of the corolla narrow-oblong and widely spreading ; style as long as 

 the tube of the corolla and twice as long as the stamens; leaves all 

 simple, lance-oblong, deep green. 



F. suspensa, Vahl. (F. Fortt;ni). Shrub with long and slender, weak, 

 nearly terete branches, some of them reclining; flowers yellow, with 

 corolla lobes longer, wider, more obtuse, and more spreading than in 

 the preceding; style half shorter than the corolla tube and stamens; 

 leaves simple and trifoliolate, often on the same bush (if compound, 

 the lateral leaflets small), broadly ovate. Branches bearing corky dot- 

 like elevations. Often treated as a climber. Less common than the 

 other. 



3. S YRINGA, LILAC. (From Greek word for tube, alluding either to 

 the tubular corolla or to the twigs, used for pipe-stems.) Familiar 

 ornamental tall shrubs, from the Old World, with scaly buds in the 

 axils of the leaves, but hardly ever a terminal one (so that there is only 

 a pair at the tip of a branch), entire leaves on slender petioles, and 

 crowded compound panicles or thyrsus of mostly fragrant flowers, in 

 spring. The name Syringa is often applied to the Philadelphia (see 

 p. 168).
