HYDRANGEA 629 



hydrangeoides," a name that belongs to an allied but quite distinct climber. 

 In place of the three- to six-parted sterile blossom of the present species, the 

 sterile flower of the Schizophragma consists of a single ovate sepal, I to i 

 ins. long. 



H. QUERCIFOLIA, Bartram. 



A deciduous shrub, up to 6 or more ft. high in a wild state, rarely seen 

 more than half as high in this country ; young shoots thick and stout, woolly 

 Leaves broadly oval or broadly ovate, sometimes roundish in general outline, 

 but five- or seven-lobed, after the fashion of the large-leaved American 

 red oaks like Quercus rubra ; minutely toothed, 3 to 8 ins. long, two-thirds 

 to fully as wide ; dark dull green and smooth above, downy beneath ; stalk 

 i to i\ ins. long. Panicle erect, 4 to 8 ins. high, round-topped, pyramidal. 

 Outer flowers sterile, I to i^ ins. diameter, white, changing with age to 

 a purplish shade. Fertile flowers very numerous, crowded, \ in. diameter ; 

 petals five, oblong. Flower-stalks furnished with loose hairs. Blossoms 

 from June to September. 



Native of the south-eastern United States ; introduced in 1803. From 

 all the cultivated Hydrangeas this is readily distinguished by its large 

 scalloped leaves. It is very handsome both in foliage and flower, but 

 is unfortunately rather tender. It suffers at Kew, but in such gardens as 

 that of Canon Ellacombe at Bitton, or Mrs Chambers' at Haslemere, 

 where the conditions are rather more favourable, it thrives remarkably well. 

 It is quite uncommon, and deserves a sheltered position. Propagated by 

 layering. A broader-leaved form is sometimes distinguished as "H. 

 platanifolia." 



H. RADIATA, Walter. 



(H. nivea, Michcux?) 



A deciduous shrub, 3 to 5 ft. high ; young branches soon becoming smooth. 

 Leaves ovate or oval, 2 to 6 ins. long, I to 3 ins. wide ; tapered or rounded at 

 the base, taper-pointed, toothed ; upper surface dark green, downy along 

 the veins ; lower one covered with a close snow-white felt ; stalk I to 2 

 ins. long. Corymbs rounded, 4 to 8 ins. across, always with a few large, 

 sterile, long-stalked flowers at the margin, which are I to i ins. across, 

 and white. Fertile flowers very small and numerous, white. Seed-vessels 

 shaped like those of a poppy, with the calyx adhering at the top. Blossoms in 

 July. 



Native of N. and S.' Carolina ; introduced in 1786. The vividly white 

 under-surface of the leaf distinguishes this Hydrangea from all others 

 in cultivation, and gives it a peculiar interest. It is allied to H. arborescens, 

 with which H. cinerea forms a connecting link. 



H. SARGENTIANA, Rehder. 



(Bot. Mag., t. 8447.) 



A deciduous shrub of bushy habit, up to 6 ft. high ; young shoots very 

 stout, ribbed, and thickly clothed with stiff transparent bristles and small 

 erect hairs, giving the shoot a remarkable, somewhat mossy aspect. Leaves 

 ovate, with a rounded base, 4 to 5 ins. long, 2 to 3 ins. wide on the flowering 

 shoots ; broadly ovate, with a heart-shaped base, 6 to 10 ins. long by 4 

 to 7 ins. wide on the sterile shoots, deep dull green, and covered with minute 

 hairs above ; pale, bristly, and prominently net-veined beneath ; stalk I 

 to 4^ ins. long, bristly and downy. Flowers produced in July and August
