plants, grafted from this very tree, covered with spines. The species 

 is said to have been introduced in 1812; but we have not heard of any 

 plant larger or older than that of Messrs. Loddiges, which, in 1835, was 

 12ft. high, after being 10 years planted: the same year, for the first time, 

 it flowered, and ripened a few haws, which were almost solitary, and in 

 form and colour resembled those of the common hawthorn. 



Variety. 



¥ C. a. 2 minor, C. apiifolia Lodd. Cat., {fig. 588. in p. 860.) has the 

 leaves smaller than those of the species, and more fringed at the 

 edges, like those of the common parsley ; but this fringed ap- 

 pearance is by no means constant, either in the variety or in the 

 species. This variety forms a most ornamental low bush ; or a 

 beautiful pendent tree, when grafted standard high. 



§ ix. Microcarpcc. 



Sect. Char. Fruit small, round, red. Flowers small, produced in corymbs, 

 later in the season than in any of the other species. Spines few, but some- 

 times very large.

Spec. Char., Sj-c. Disks of leaves cordate-ovate, angled by lobes, glabrous. 

 Petioles and calyxes without glands. Styles 5 in a flower. (Dec. Prod., ii. 

 p. 628.) A native of hedges and rocky places, from Canada to Virginia. 

 A compact close-headed small tree. The leaves of a deep shining green, 

 and the flowers and fruit produced in numerous terminal corymbs. The 

 size of the leaves varies exceedingly, according to the soil, and the age of 

 the plant. This is a very distinct and handsome species ; and, from the 

 plant in Messrs. Loddiges's arboretum, we should think it would attain the 

 height of 20 ft. or 30 ft. in about the same number of years. It was intro- 

 duced in 1738, and flowers in the end of June or beginning of July. 



Statistics. In Staffordshire, at Trentham, 26 years planted, and 11 ft. high ; at Alton Towers, 10 

 years planted, and 16 ft. high. In Worcestershire, at Croome, 20 years planted, and 25 ft. high. In 

 Scotland, in the Edinburgh Botanic Garden, 87 years planted, and 12 ft. high ; at Hopetoun 

 House, 18 years planted, and 12 ft. high.

Spec. Char.,cfc. Subspinose. Leaves in fascicles, oblong-cuneated,3-cleft, lobed 

 and crenated, smooth, shining. Corymbs many-flowered. Calyx smooth ; 

 segments ovate, quite entire. Fruit ovate, subrotund, smooth, 5-celled ; 

 shell thin. (Lindl. Bot. Reg., t. 1846.) A native of the upper districts of 

 Georgia and Carolina ; and growing to a small tree, from 12 ft. to 15 ft. high. 

 Introduced by Lyon, in 1806; flowering in May and June, and ripening its 

 small bright red fruit in October. In this country, it is a slow-growing, very 

 neat, little tree, with slender, smooth, drooping branches, and something of 

 the habit of C. Oxyacantha. Its leaves have a very handsome appearance, 

 and are remarkably shining, and deep green : they usually grow in clusters ; 

 have a long stalk, tapering upwards into a blade, which is sometimes nearly 

 entire, with only a tooth or two at the end ; sometimes they are 3-lobed, 

 with crenated segments ; and occasionally they are deeply 3-parted ; their 

 form is always mc:e or less spathulate. The stipules of the more vigor- 

 ous branches are large and leafy. The flowers are white, and appear in 

 May, or the beginning of June, at the same time with those of C. cordata, 

 and later than most others. The fruit is rather abundant, but small ; and,
