THE FLOKAL WORLD AND GARDEN GUIDE. 323 



C. 0. multiplex, the double white-flowered, one of the most 

 eflective white-flowering trees of its season, and a charming thing 

 when well grown in a pot, in the form of a small bush, for the 

 conservatory. 



C 0. piniicea, single scarlet-flowered. The flowers are exceed- 

 ingly rich in colour, and they emit a delightful fragrance. In autumn 

 the tree is loaded with berries. 



O. 0. rosea superha, single rose-flowered ; a charming tree for the 

 garden, or to flower as a dwarf pot tree in the conservatory. 



C. 0. rosea Jlore-pleno, double pink-flowered. A single sprig of 

 its flowers is like a bouquet, the colour bright and cheerful. It is 

 not very fragrant, and rarely produces berries. 



C. 0. florihics coccineus plenis, double-flowering scarlet. This is 

 the variety represented in the coloured plate. The colour is not a 

 true scarlet, but rather a deep pinkish red, remarkably effective when 

 seen in a mass, supported as it is by an abundant bright green 

 leafage. This splendid thorn was first presented to public notice at 

 the International Horticultural Exhibition of 1866, where it was at 

 once pronounced a valuable acquisition to our collections of hardy 

 flowering trees. The variety first originated as a " sport " in the 

 garden of Mr. Boyd, of Waltham Cross. It was again exhibited at 

 the early summer shows at Eegent's Park in 1867 and 1868, by 

 Messrs. Paul and Sou, of Cheshunt. 



C. Ifexicana, the Mexican thorn, is an evergreen species of most 

 elegant habit and free growth, which soon proves an eflective specimen 

 on a lawn. The flowers are w^hite, the fruit yellowish ; requires 

 plenty of room for full development. 



C. lohata pendiila, a fast free-growing tree of elegant pendu- 

 lous outline ; the leaves are unequally lobed, the flowers are white, 

 and produced in loose corymbs. Requires plenty of room for full 

 development. 



G. 0. pendula nova, a new '' weeping " variety of hawthorn of 

 extremely elegant habit, admirably adapted for a spacious lawn or 

 for a good open position in the arboretum. 



C pyracantlia, one of the finest of all evergreen wall-trees', and 

 rather scarce. Once seen in autumn, with its huge bunches of 

 scarlet-orange berries contrasting finely against its dark green 

 leaves, it can never be forgotten. AVhy we should so seldom 

 meet with this tree, both in gardens and nurseries, is to us a mystery. 

 It cannot be that there is any difficulty in propagating it, because it 

 may be raiised from seed with certainty, and also from cuttings 

 taken at the end of July, and kept close in a pit or frame for six 

 months. We have grown this thorn largely in pots, the trees being 

 moderately shortened back with the knife in autumn, and kept to 

 about three feet in height. In autumn they are covered with berries, 

 and are employed with Skimmias, etc., in the plunging system, where 

 they light up the front lines of evergreen shrubs until the spring 

 flowers begin a<,'ain. 



C, tanacetifolia, the tansy-leaved thorn, a fine free-growing tree 

 with deeply-cut leaves, white flowers, and yellow berries. 



Less to be regarded as garden trees, yet deserving the first con-
