or brown colour, and rough and scaly ; the fruit is small, round, and most 

 commonly of a dark purple; but it varies to pule yellow, or a milk white, 

 and red, on the same plant. It ripens about the end of July, and is very 

 soft and juicy, but soon drops off. The tree is interesting from its early 

 flowering, and the dark colour of the anthers of its flowers, which con- 

 trasts strongly with the whiteness of the petals. The leaves are also 

 large, and oi'a peculiar shape. (See p. 857.) 

 Variety t 



ZC.p.2 altdica, C. altaica Led., Lod. Cat., (fig. 583. in p. 858.) has the 



leaves somewhat more deeply lobed and finely serrated than those 



of the species. 



vi. Dougldsli. 



Serf. Char. Leaves small, and not lobed as in the preceding section ; fur- 

 nished with numerous parallel nerves, somewhat like those of C. punc- 

 tata. Spines rather numerous and rigid. Fruit small, and dark purple ; 

 pulp soft and watery.

Spec. Char., Sfc. A small tree. Branches ascending. Spines rigid, straightish, 

 now short, now very long. Leaves some obovate, some oval, gashedly ser- 

 rated, acute ; at the base wedge-shaped, glabrous ; in the autumn, remark- 

 ably leathery, and they then acquire a purplish cast, and are shining : they 

 fall off at about the same time as those of C. punctata and of C. joyrifolia. 

 Flowers produced in May, and are of a middling size. Fruij small, and 

 dark purple. (Bot. Reg., t. 1810.) This is a very distinct sort, more par- 

 ticularly as it respects the colour of the fruit, and the colour and texture 

 of the leaves. The general habit of the plant is fastigiate ; and it is one 

 of the latest kinds in leafing in the spring. The flowers and fruit are 

 produced in great abundance, and both are very ornamental. The fruit is 

 very soft and juicy, and ripens early in August, but soon drops off.

Sect. Char. Leaves small, obovate, slightly lobed, and serrated. Flowers 

 frequently solitary. Spines numerous, straight, and more slender than in 

 any other division. Fruit top, or pear, shaped ; yellow, or greenish yellow.

Spec. Char., Sfc. Disks of leaves obovate-wedge-shaped, slightly lobed, cre- 

 nately serrate, upon short petioles. Stipules glanded. Flowers mostly 

 solitary. Sepals glanded. Fruit top-shaped, yellow, or yellowish green. 

 Nuts 4 in a fruit. (Dec. Prod. y ii. p. 628.) A native of North America, 

 from Virginia to Carolina. A spreading tree, of rapid growth ; but the shoots 

 are rather slender, and the species not very vigorous. The bark of the 

 trunk is rough, and scales off. The flowers and the fruit are neither pro- 

 duced in abundance, nor make any great show ; but the tree has a marked 

 character from its general form, and the horizontal tendency of its branches. 

 It was introduced in 1724; grows to the height of from 20ft. to 25ft., 

 flowers in May, and ripens its haws in October. A tree at Holland House 

 is 20 ft. high, with a head 25 ft. in diameter. There are larger trees at 

 White Knights; and one at Grimston, in Yorkshire, 14 vears planted, is 

 22ft. high.
