THE GARDENER'S ASSISTANT. 



Itea virginica. — A dwarf shrub resembling a Willow 

 in habit and foliage ; flowers white, on erect spikes, pro- 

 duced in great profusion towards the end of summer. 



Fig. 373.— Ilex cornuta. (J.) 



Thrives best in a cool peaty soil and half-shady situation. 

 North America, 1744. 



Jamesia americana. — A shrub 3 to 4 feet high. Leaves 

 opposite, lanceolate, toothed ; flowers white, in terminal 

 panicles. Rocky Mountains, 1865. 



Jasminum. — Some of the Jasmines are nearly evergreen, 

 others deciduous ; they are valuable for covering house- 



4.— Ilex opaca. 



fronts near the sea in the south-west. They are of 

 rambling, not strictly climbing, habit, and the flowers 

 have an agreeable fragrance. 



J. fruticans. — An almost erect half-evergreen species, 

 with glossy three-leafleted leaves, and yellow flowers 

 produced all through the summer. Fruits black and 

 handsome. Southern Europe, 1570. 



J. nudiflorum. — This has yellow flowers produced 

 throughout the whole length of the flexible green branches 

 from November onwards through the winter. China, 

 1844. 



J. officinale, White Jasmine. — This is a fast grower, 

 and will soon cover a large space. Its slender deep-green 

 branches give it the appearance of an evergreen, although 

 its leaves are deciduous. In its beautiful pinnate leaves 

 and pure white sweet-scented flowers it is unequalled by 

 any other of its class. It blooms from May till October. 

 Asia, 1548. 



J. revolutum. — This has pinnate leathery leaves, and 

 yellow flowers borne in terminal clusters all through the 

 summer. «/„ pubigerum is a variety in which the young 

 shoots and leaves are hairy and the flowers smaller. 

 Northern India, 1812. 



Juglans. — The Walnut genus consists of handsome 

 bold -habited trees, with pinnate leaves. 



/. nigra. — A rapid - growing tree, of less spreading 

 habit than the following, attaining a height of 60 to 

 100 feet. North America, 1656. /. cinerea is a some- 

 what similar and equally handsome tree, also North 

 American. /. cordiformis and J. Sieboldiana from Japan, 

 and /. rnandshurica from Amurland, are new introduc- 

 tions which promise to be fine trees for this country. 

 They have longer leaves than the others. 



/. rcgia, Common Walnut. — A well-known fruit-bearing 

 tree, 70 to 80 feet. Western Asia, about 1650. Among 

 the ornamental varieties laciniata is one of the best. 



Kadsura japonica. — A trailing rather tender shrub, 

 with simple leaves, and solitary axillary yellowish -white 

 flowers an inch in diameter, succeeded by heads of scarlet 

 berries. Japan, 1846. 



Kalmia. — Compact evergreen shrubs of small stature, 

 with undivided leaves and showy hemispherical or bell- 

 shaped flowers. Natives of North America. 



K. angustifolia, Sheep-Laurel. — A dwarf shrub 1 to 

 2 feet high ; leaves narrow, usually in threes ; flowers 

 smaller than in K. latifolia, and of a dark-red colour, 

 produced from May to July. 1736. 



K. glauca. — This grows to about the same height as 

 the last, but is of less compact habit and has glaucous 

 leaves ; its lilac-purple flowers are produced in April. 

 1767. 



K. latifolia, Calico Bush. — This and its varieties are 

 most ornamental. They have shining leaves of a pleasing 

 bright -green, and dense terminal clusters of beautiful 

 delicate pink, rose, or nearly white spotted flowers, pro- 

 duced from May to July. 1734. K. myrtifolia is a 

 miniature small-leaved variety. 



Kerria japonica. — A small shrub with slender, dark- 

 green branches, lanceolate leaves, and orange - yellow 

 terminal flowers. The familiar double-flowered variety 

 was one of the earliest introductions from Japan, having 

 been in British gardens since 1700. The single -flowered 

 variety and the one with variegated foliage are better 

 for growing in the open than the double variety, which 

 is better on a wall. It used to be known as Corchorus 

 japonica. 



Kcelreuteria paniculata.—A small tree of irregular 

 growth, with unequally-pinnate leaves, yellow flowers in 

 large terminal panicles, and bladdery seed-vessels. A 

 desirable ornamental tree, flowering during the summer. 

 North China, 1763. 



Laburnum vulgare. — The Laburnum in its several 

 forms is a universally admired European tree, bearing a 

 profusion of drooping racemes of yellow flowers in May. 

 Parkesii and Watereri have much longer racemes and
