 Engravings. Fig. 554. ; and y?g. 586. in p. S,:-o. 



Spec. Char. t 3rc. Branches 

 a little villose. Disks 

 of leaves ovate, une- 

 qually serrated, or 

 lobed, slightly downy 

 beneath, upon very 

 short petioles. Sti- 

 pules cut. Flowers in 

 loose corymbs. (Dec. 

 Prod., ii. p. 628.) A 

 tree closely resembling 

 C. flava in general ap- 

 pearance, and differing 

 from it only in having 

 some of the leaves with 

 larger lobes, and some 

 of the spines larger. The flowers are sparingly produced, among dense 

 tufts of leaves; and the fruit, which is green when ripe, is still less abun- 

 dant. It is pear-shaped, and very different from every other kind of 

 Crata3 gus, except C. flava and C. f. trilobata.

Identification. Lodd. Cat., edit. 1832. 



Synonyme. C. spinosissima Lee. 



Engravings. Fig. 587. in p. 860. ; and the plate in our Second Volume. 



Description, $c. Leaves ovate-cuneate, notched and serrated. Petioles 

 slender. Surface flat, shining, somewhat veined. Branches small, thickly 

 beset with slender thorns. Habit spreading. A hybrid, raised from seed in 

 the Hammersmith Nursery, about 1820, or before. It forms a tree in general 

 appearance resembling C. flava, but with the branches much less vigorous, 

 and more thorny. The fruit is yellow, slightly tinged with red; and what 

 distinguishes it from the two allied sorts is, that its leaves die off, in autumn, 

 of an intensely deep scarlet. The only large specimen we know of this kind 

 of thorn is in the arboretum of Messrs. Loddiges; but there are young plants 

 of it in the Hammersmith and other nurseries. 



viii. Apiifblife. 



Sect. Char. Leaves deltoid, or somewhat resembling those of the common 

 thorn. The fruit is also of the same colour ; but the tree has a totally 

 different habit, having the shoots loose and spreading, weak, and almost 

 without thorns.

Spec. Char., fyc. Leaves deltoid, cut into lobes that are acute and incisely 

 toothed. Pedicels in the corymb villose, mostly simple. Tube of calyx 

 villose. Sepals obscurely serrated. Fruit scarlet. (Dec. Prod., ii. p. 627.) 

 A native of moist woods in Virginia and Carolina. According to Nuttall, 

 it is highly serviceable for the formation of hedges ; but an imported plant in 

 the arboretum of Messrs. Loddiges has a loose spreading head, with weak 

 rambling branches, almost destitute of thorns, and by no means gives the 

 idea of a plant adapted to hedges. All the species of 6 T ratse v gus, however, 

 are liable to vary in an extraordinary manner, and we have seen young
