T. RADICANS (_syn Bignonia radicans_).--Trumpet Flower. North America, 1640. An old occupant of our gardens and one of the most beautiful wall plants in cultivation. It is a tall climber, of sometimes fully 20 feet in height, with graceful pinnate leaves, and handsome trumpet-shaped scarlet-red flowers, that are at their best about mid-summer, though the period of flowering extends over a considerable length of time. The stems are long, twisted, and wiry, and like those of the Ivy send out roots at the joints and so fasten the plant in position. Few climbing plants are more attractive than the Trumpet Flower, and being hardy in most parts of the country, and free of growth, is to be recommended for covering walls, and arches, or similar structures. T. radicans major is of more robust growth than the species, with larger foliage and paler flowers. The orange-scarlet flowers are produced in terminal corymbs. TILIA. TILIA VULGARIS (_syns T. europea_ and _T. intermedia_).--Lime, or Linden Tree. Europe, Caucasus, and naturalised in Britain. Probably none of the Limes would be included in a list of ornamental-flowering trees and shrubs, still that they are of great interest and beauty even in that state cannot be denied. The common species as well as its numerous varieties have sweetly scented, yellowish-white flowers in terminal cymes, and are, though individually small, highly ornamental when fully developed. Other species of great interest when in flower are T. alba (_syn T. argentea_), Silver Lime; T. petiolaris, a curious and beautiful species; and T. euchlora. The various species and varieties of Lime succeed well in almost any class of soil, but rich loam on sand is considered the most suitable for their perfect development. ULEX. ULEX EUROPAEUS.--Furze, Gorse, or Whin. This pretty native shrub needs no description, suffice it to say that it is one of the handsomest-flowering shrubs in cultivation. U. europaeus flore-pleno (Double-flowered Gorse) is even more beautiful than the species, the wealth of golden flowers almost hiding the plant from view. U. europaeus strictus (Irish Furze) is of more erect and slender growth, and less rigid than the common species. U. NANUS.---Dwarf Gorse, Cat Whin, and Tam Furze. This differs considerably from the common plant, not only in stature, but in the time of flowering. In this species the bracts at the calyx base are small compared with those of U. europaeus, while the smaller flowers are produced during summer, and when not a bloom is to be found on its supposed parent. It is of dense growth, the tallest stems rarely rising from the ground to a greater height than about 15 inches. All the Furze family succeed admirably in the poorest of soil; indeed, a dry gravelly bank would seem to be their favourite haunt. VACCINIUM. VACCINIUM CORYMBOSUM.--Canada to Carolina and Georgia, 1765. This is one of the most beautiful and showy species, with dense clusters of small, pinky flowers.
