CARYA CARYOPTERIS 301 



satisfactory of the hickories in cultivation. Mr Elwes knows only one of 

 any size, which is 30 ft. high, and grows in Tortworth Churchyard. 



C. TOMENTOSA, Nuttall. MOCKER NUT. 

 (Hicoria alba, Britton.} 



A tree 50 to 60, occasionally 100, ft. high ; winter buds large, the terminal 

 one broadly egg-shaped, pointed, | to | in. long, and ^ in. or more wide ; the 

 inner scales covered with a soft pale felt ; young shoots very downy, especially 

 at first Leaves fragrant, 8 to 12 ins. (on very vigorous young trees 20 ins.) 

 long ; composed usually of seven (sometimes five or nine) leaflets. Terminal 

 leaflet is 5 to 8 ins. long, 2 to 4^ ins. wide, obovate, wedge-shaped at the base ; 

 basal pair sometimes only i to 2 ins. long, ovate, rounded at the base ; the 

 middle pair or pairs are intermediate in size and shape. All taper-pointed, 

 toothed, upper surface dark green, downy on the midrib ; lower surface 

 yellowish, and covered with starry down and glands ; common stalk stellately 

 downy. Male catkins 3 to 5 ins. long, very downy. Fruit top-shaped or 

 roundish. 



Native of Eastern N. America ; rare in cultivation. The species is distinct 

 in its large winter buds (it is sometimes called "big-bud hickory") and in the 

 fragrance of its foliage. This, of course, is most marked when the leaf is 

 rubbed, but on dewy mornings in summer it can be perceived many yards 

 away from the tree. The mocker nut has been too much neglected in gardens, 

 if only on this account. There is a fine specimen at Kew 50 ft. high, remark- 

 able for its stately habit and splendid foliage. 



CARYOPTERIS MASTACAXTHUS, Schauer. VERBENACE^L 



(Bot. Mag., t. 6799 ; C. incana, Migui .) 



A deciduous bush, 4 to 8 ft. high, of spreading habit ; young stems 

 semi- woody, covered like the flower-stalks, leaf-stalks, and the under- 

 side of the leaves, with a close grey felt. Leaves opposite, ovate; 

 i to 3 ins. long, J to ij ins. wide; the base more or less broadly wedge- 

 shaped, the apex blunt or pointed ; coarsely toothed, almost lobed, dull 

 green and downy on the upper surface ; stalk J to f in. long. Flowers 

 bright violet-blue, produced during October in hemispherical cymes from 

 the axils of the uppermost leaves : main flower-stalk | to i J ins. long. 

 Corolla downy, tubular, -J in. long, with five lobes at the mouth; the 

 four upper ones ovate, the lower one larger, scoop-shaped, and fringed ; 

 stamens four, much protruded; calyx funnel-shaped, with five-pointed teeth. 



Native of China and Japan ; originally introduced in 1844 by Fortune, 

 who found it wild near Canton. It was at first treated as a greenhouse 

 plant, and being scarcely worth its room there, was eventually lost until 

 reintroduced by Maries in 1880. It is hardy at Kew in all but the 

 hardest winters, and during a fine autumn makes a very pretty display. 

 The leaves are pleasantly scented. It is increased with the greatest ease 

 by means of soft cuttings in heat, and should be grown in an open, sandy 

 soil, and given a sunny, sheltered position. 



Var. CANDICANS, Schelle (syn. alba), has whitish flowers, but is not, I think, 

 so hardy as the type.
