on account of the rich autumnal tints should be planted freely 

 in public gardens and parks. C. Aza7'olus is of vigorous growth, 

 and frequently reaches a height of 20ft. ; its white fragrant flowers 

 are borne in May, and ils orange-red fruits are large and 

 effective in autun-^n. C. A. A?'07iia {C, Aroma), popularly called 

 the Aronia Thorn, is a native of the Levant, of good growth, 

 and bears a large display of white flowers in June. It is a 

 conspicuous object in the landscape in autumn when laden with 

 its large yellow fruit. It is a grand law-n tree. C. monogyna 

 is free in growth, and of a distinct, pendulous habit; when in 

 full flower it is very beautiful. C. m. crantoneiisis has larger 

 flowers of a purer white, and is of elegant habit. C. m. stricta 

 is somewhat similar in growth to the Lombardy Poplar, and for 

 gardens of limited size should not be overlooked ; the w^hite 

 flowers are borne with moderate freedom. C. m. fiexiiosa, C. m. 

 sempe7'fiorens, C. m. Regijics^ and C. m. prcecox^ are show^y. The 

 leaves of C. Crus-galli arbutifolia turns to a brilliant crimson in 

 autumn, and for this reason the variety should be planted 

 extensively. C. C.-g. ovalifolia^ C. C.-g. liitearis, C. C.-g. fontan- 

 esiana, C. C.-g. pyracanfhifolia {salicifolia\ and C. C.-g. splendens, 

 are very ornamental. C. oxyca?ithoides flore-pleno 7'osea (double 

 rose-coloured Thorn) is one of the most delightful of June- 

 blossoming shrubs ; its flowers are borne with great freedom, and 

 continue long in perfection. C 0. florepleno cocciiiea (double 

 scarlet) should be planted freely in the park and garden ; like 

 the last-named, its bright red flowers remain long in beauty. 

 C. 0. lucida produces a wealth of double white flowers, and makes 

 a capital companion to the last-named. The flowers of C. 0. 

 flore-puniceo are single, red, very attractive, and borne freely. 

 C. 0. atrofiisca is a beautiful weeping Thorn, with medium- 

 sized pure white flowers. C. hetej^ophylla {C. viultiflord) is a 

 dense-headed tree of low growth ; its white flowers are borne 

 early in spring, and it retains its leaves until early winter, 

 while its crimson fruit is efl*ective, and hangs on the tree 

 for the greater part of the winter. C. coi'data (C. acerifolid) 

 is a handsome American species, with a round top and shining 

 green leaves, which, in September, turn to crimson-scarlet ; the 

 white flowers are produced in dense terminal corymbs late in 

 the season. C. orieiitalis {C. odoratissima and C. flabellatd) 

 grows 20ft. high w^hen treated generously; it is freely branched, 

 slightly pendulous, and one of the latest to start into growth in 

 spring, but when mantled with w^hite blossom is delightful. 

 C. pinnatifida, a choice Thorn, bursts into leaf early in spring, 

 and is conspicuous in autumn, when its decaying leaves take on 

 shades of yellow and brown. Its fruits are large and attractive. 

 C. parvifolia is a valuable late-flowering Thorn. It is rather 

 slow in growth, and prefers partial shade to full exposure. It 

 forms a low, much-branched tree, armed wdth very long sharp
