432 CRAT^EGUS 



C. ORIENTALIS, P alias. 



(C. odoratissima, Lindley, Bot. Reg., t. 1885.) 



A small, nearly unarmed tree, 15 to 20 ft. high, with a rounded or flattish, 

 spreading head of branches, often pendulous at the ends ; young branchlets 

 at first covered with whitish hairs, many of which fall away by the end of the 

 season. Leaves mostly triangular or lozenge-shaped ; I to 2 ins. long, nearly 

 or quite as much wide ; wedge-shaped to almost square at the base, more or 

 less deeply cut (often nearly to the midrib) into five to nine narrow oblong 

 lobes, which are themselves jaggedly toothed at the points ; dark green above, 

 grey beneath, downy on both sides ; stalk j to f in. long ; stipules \ in. across, 

 with a few large teeth. Flowers f in. across, white, produced in early June in 

 corymbs of twelve or more blossoms ; calyx and flower-stalks grey-woolly ; 

 stamens twenty. Fruit coral red or yellowish red, | in. diameter, globose, 

 downy. 



Native of the Orient; introduced in 1810. This beautiful thorn is much 

 planted in the south of England, and is common in some of the London parks. 

 Both in flower and fruit it is a charming tree. 



Var. SANGUINEA, London (C. orientalis, Liridley, in Bot. Reg., t. 1852). 

 Laxer than the type in habit, but with the lobes of the leaf broader on the 

 whole. Fruit not so downy, and of a dark dull or purplish red. Not so 

 effective in fruit as the type. This appears to be the same as C. Tournefortii, 

 Grisebach. 



C. OXYACANTHA, Linnczus. HAWTHORN or MAY. 



A small thorny tree, up to 15 or 20 ft. high, wilh thorns I in. long. Leaves 

 mostly obovate, three- or five-lobed, wedge-shaped at the base, the lobes 

 rounded or pointed ; toothed, dark glossy green, smooth except when quite 

 young ; ^ to 2j ins. long, two-thirds to as much wide ; stalks slender, \ to f 

 in. long. On strong, barren shoots the leaves are often more deeply lobed, 

 and with large, gland-toothed stipules. Flowers white, f in. diameter, pro- 

 duced during May six to twelve together in corymbs, the leaves at the time 

 almost fully grown ; calyx and flower-stalks smooth ; stamens about twenty, 

 anthers red ; styles two or three. Fruits roundish ovoid, \ to f in. long, red, 

 containing two, sometimes three stones. 



Native of Europe, including Britain, and one of the two forms (now usually 

 regarded as distinct species) known popularly as "may" or "hawthorn." The 

 other is C. monogyna (q.v.\ which is best distinguished by having only one 

 style and one stone in the fruit. Although C. Oxyacantha has not broken up 

 into so many varieties as monogyna, to it belong some of the very best garden 

 forms of hawthorn. None make lovelier lawn trees. 



Var. ALBA PLENA. Flowers white, double, changing to pink with age. 



Var. CANDIDA PLENA. Flowers double, white, remaining pure. 



Var. COCCINEA. Flowers scarlet, single. 



Var. COCCINEA PLENA, Paul's double scarlet thorn. The best of all 

 double-flowered red thorns. Var. SALISBURIFOLIA is a variant of it, with 

 curly, distorted branches and dwarf habit. There are various minor forms of 

 red thorns, both single and double, with such names as "punicea," "rosea," 

 and "rubra," which represent slight variations of colour. 



Var. FRUCTU-LUTEO (xanthocarpa). Fruit yellow. 



Var. GIREOUDI. Leaves of the later growths mottled with white and pink. 



C. PENTAGYNA, KitaibeL 



A small tree, 15 to 20 ft. high, with hairy young shoots ; thorns few, ?. in. 

 long. Leaves broadly tapered or nearly straight at the base, lobed ; i to 3
