DIERVILLA 491 



D. GRANDIFLORA, Siebold. 

 (D. coraeensis, DC Candollt?) 



A deciduous shrub, 6 to 10 ft. high ; young branchlets smooth. Leaves 

 3 to 5 ins. long, 2 to 3 ins. wide ; oval or obovate, with a long, abrupt point, 

 nearly or quite smooth above, hairy on the midrib and chief veins below ; 

 stalks J to f in. long, bristly. Flowers produced during June in corymbs 

 usually of threes, terminating short lateral twigs. Corolla bell-shaped, abruptly 

 narrowed near the base ; I to I \ ins. long, f in. across at the five-lobed mouth, 

 not downy ; pale rose at first, changing to carmine. Calyx with five narrow, 

 linear lobes \ in. long ; ovary smooth. 



Native of Japan, but not, according to Siebold, of Corea, as the name 

 corasensis implies. The distinguishing characters from D. florida are the 

 linear calyx-lobes reaching to the base, the longer-stalked leaves, and the 

 smooth ovary. It is a very free-flowering, handsome shrub. 



DIERVILLA FLORIDA VARIEGATA. 



D. JAPONICA, De Candolle. 



(Weigela japonica, Thunberg?) 



A deciduous shrub, 6 to 8 ft. high ; young shoots nearly smooth. Leaves 

 oval or ovate, 2 to 4 ins. long, about half as wide ; toothed, long and taper- 

 pointed, densely felted with pale down beneath ; slightly hairy above ; stalk 

 in. or less long, bristly on the edges. Flowers mostly in threes, terminal and 

 in the leaf-axils of short side twigs, forming a leafy panicle 3 to 5 ins. long. 

 Corolla between funnel- and bell-shaped, I to ij ins. long, less in width, 

 rather downy outside ; pale rose at first, changing to carmine. Calyx-lobes 

 linear, more or less downy. 



Native of Japan and China. It is allied in botanical characters to 

 D. floribunda, having the corolla downy outsidej and the calyx-lobes slender 

 and downy ; but the corolla is much larger and differs in colour very much 

 from the almost blood-red one of D. floribunda. The garden varieties with 

 leaves more or less felted beneath, derive that character from this species. 



Var. HORTENSIS, Rehder (D. hortensis, Siebold}. Flowers white ; leaves 

 nearly white with down beneath. Not so hardy and vigorous as the type. 

 Var. NIVEA has purer white flowers.
