comparatively slender, the plant less robust, and the fruit smaller, 

 than in the species. It is a very distinct and elegant variety. 



¥ C. O. 7 pteridifblia, C. ;;terifolia Lodd. Cat., C. pectinata Hort., 

 {Jig. 604. in p. 865.) resembles the preceding, but the leaves are 

 longer in proportion to their breadth, and more elegantly cut. 

 There are only small plants of this very elegant and most inte- 

 resting variety in the Fulham Nursery, at Messrs. Loddiges, and in 

 one or two other collections. 



¥ C. O. 8 eriocdrpa Lindl., C. eriocarpa Lodd. Cat., {fig. 607. in p. 865., 

 and the plate in our Second Volume) is a robust rapidly growing 

 variety, with large leaves, and strong thick shoots ; a clear white 

 bark, and few thorns. It is very prolific in flowers, and the fruit 

 which succeeds them is woolly in its young state, but not large. 

 There are fine trees of this very distinct variety in the Horticultural 

 Society's Garden. If ever the hawthorn should be cultivated for 

 its timber, to supply the wood engravers as a substitute for box, 

 this variety, and C. O. melanocarpa will deserve the preference. 



¥ C. O. 9 purpurea Penny (fig. 611. in p. 866.) has large leaves, and 

 the young shoots are of a dark purple colour. It was raised from 

 seed, some years ago, in the Epsom Nursery, but has not yet 

 flowered. 



¥ CO. 10 Olivernina; C. Oliveridna Bosc, Dec. Prod., ii. p. 630., and 

 Don's Mill., ii. p. 601.; C. Oliven'a Lodd. Cat.; C. orientalis Lodd. 

 Cat.; (fig. 606. in p. 865., and the plate in our Second Volume) 

 has the leaves small and hoary, and the fruit also small and black. 

 It forms a very distinct variety, and is accounted by some a species. 

 There are handsome plants of it in the Horticultural Society's 

 Garden. 



¥ C. O. 11 melanocarpa, C. fissa Lee, C. Oxyacantha platyphylla Lodd. 

 Cat^ C. platyphylla Lindl. in Bot. Reg. y t. 1874., (fig. 605. in p. 865., 

 and the plate in our Second Volume) also has the fruit black, as the 

 name implies. It differs from the preceding variety chiefly in being of 

 more vigorous growth, and in having its leaves much less hoary. There 

 is a tree of this variety, in the Hammersmith Nursery, of extraordinary 

 vigour and beauty ; it has not been above ten or twelve years planted ; 

 but it is upwards of 20 ft. high, with a straight smooth-barked 

 trunk, and a head 25 ft. in diameter, or upwards, with branches 

 depending to the ground on almost every side ; and it is, perhaps, 

 the handsomest young hawthorn in the neighbourhood of London. 

 This variety flowers at the same time as C. O. eriocarpa, that is, 

 about a week after the species ; and the two trees so closely resem- 

 ble each other in leaves and habit of growth, that, except when 

 they are in fruit, they can only be distinguished by the darker 

 colour of the bark of C. O. melanocarpa. 



¥ C. O. 12 aw-ea Hort., C flava Hort., (fig. 610. in p. 866.) has the 

 leaves like C. O. obtusata, and the fruit roundish, and of a golden 

 yellow. This is a very distinct variety, and ought never to be 

 omitted in collections. The yellow haw, Hanbury observes, is a 

 " most exquisite plant." The buds, which are among the first that 

 come out in the spring, are of a fine yellow ; and the fruit is of the 

 colour of gold. The tree is a great bearer, and retains its fruit all 

 the winter. There is a fine old specimen of this tree at Syon. 



¥ C. O. 13 aurantiaca Booth is said to have orange-coloured fruit; but 

 there are only small plants of it in the London gardens. Mr. Wil- 

 son found, in Ayrshire, a variety with greenish orange fruit. (Hook.) 



It C. O. 14 leucocdrpa, a variety with white haws, is said to have been 

 discovered in a hedge near Bampton, in Oxfordshire ; but we have 

 never seen it. According to Hanbury, it is but a paltry tree, an in- 

 different bearer, and the fruit is of a dirty white.
