488 DEUTZIA DIERVILLA 



D. VILMORIN^:, Lemoine. 



A vigorous shrub of erect habit, up to 8 ft. or perhaps more high ; young 

 shoots slightly rough with scurfy stellate hairs at first, becoming brown and 

 shining. Leaves oblong-lanceolate, rounded or broadly tapered at the base, 

 slenderly pointed, sharply toothed, 2 to 5^ ins. long, to 2 ins. wide ; dark 

 dull green and rough with stellate hairs above, grey and covered with a close 

 felt of starry down beneath ; also with simple hairs >at the sides of the midrib 

 and veins ; stalk \ to ijr in. long. Flowers in broad corymbose panicles up to 

 3 ins. long, white, I in. across. Petals ovate with the edges upturned ; wings 

 of stamens dilating upwards to about midway, then narrowing, awl-like, to 

 the anthers. Calyx-lobes linear-lanceolate, reflexed, covered like the flower- 

 stalk with grey scurf, persistent. Fruits hemispherical, in. across. 



Native of Szechuen, China ; sent to Mr Maurice de Vilmorin at Les Barres 

 by the Abbe Farge in 1897 ; introduced to England in 1905. Next to 

 D. scabra this species, I think, promises to be the most valuable of Deutzias. 

 It is a rapid grower, and its fine flowers escape damage by late frosts better 

 than those of most Deutzias do, and usually make a good display. It was 

 named after the late Madame de Vilmorin of Les Barres. Allied to D. dis- 

 color. 



D. WILSON I, Duthie. 



(Bot. Mag., t. 8083.) 



A shrub 4 to 6 ft. high, whose young branches are slightly scurfy at first, 

 soon becoming dark reddish brown ; the bark peeling. Leaves 2 to 5 ins. long, 

 f to i^ ins. wide ; ovate-oblong to oblong-lanceolate, tapered or rounded at 

 the base, acute or acuminate ; rough, with four- or five-rayed stellate hairs 

 above, dark dull green ; grey beneath, and covered with minute stellate scurf, 

 and furnished also with pale bristle-like simple hairs, especially along the 

 midrib and veins. Flowers in corymbose panicles ; each flower nearly 

 i in. across, white ; longer stamens with tapered wings, shorter ones 

 toothed. 



Native of W. and Central China ; discovered and introduced by Wilson 

 about 1901. It is a handsome shrub of the discolor group, but distinct in the 

 hairiness of the lower surface of the leaves, suggesting D. mollis when young. 



DIERVILLA. CAPRIFOLIACEvE. 



A genus of deciduous shrubs, closely allied to the honeysuckles, 

 but distinguished by having dry, cylindrical seed-vessels (capsules). 

 Leaves opposite, either shortly or not at all stalked. Flowers often three 

 on a stalk, the corolla funnel- or bell-shaped at the base, five-lobed at the 

 mouth. Calyx five-lobed, persistent. Seeds numerous. 



The Diervillas are found in Eastern N. America and in N. Asia, 

 especially in Japan and China. The Asiatic species were at one time 

 kept apart as WEIGELA, and they are not only much more beautiful 

 than the American ones (or true Diervillas), but are well distinguished 

 in various ways. The shoots of the current year are barren, the flowers 

 being borne on short lateral twigs on the year-old branches, whilst in the 

 American species they come at the end of the current season's shoots ; 

 the corolla of the Asiatic species is regular or nearly so ; in the American 

 ones it is two-lipped. There are few more beautiful summer-flowering
