C. SANGUINE A, Pallas. 



A small, mostly unarmed tree up to 20 ft. high, young shoots slightly hairy 

 at first, soon smooth, and becoming of a deep shining brown-purple. Leaves 

 diamond-shaped to ovate, always tapered at the base, with three, five, or seven 

 shallowish lobes, sharply, sometimes doubly toothed ; 2 to 3^ ins. long, i to 

 2^ ins. wide ; slightly hairy on both sides, especially in the vein-axils beneath ; 

 stalk 5- to \ in. long ; stipules semi-heart-shaped, coarsely toothed, f in. across. 

 Flowers white, in. across, in dense corymbs ; calyx and flower-stalks smooth ; 

 stamens twenty, with purple anthers ; styles ordinarily three. Fruit bright red, 

 globose, scarcely \ in. long. 



Native of the" vast region extending from S.E. Russia across Siberia; 

 introduced early in the nineteenth century. It belongs to the same group as 

 altaica, chlorosarca, and dsungarica. The colour of its twigs is rather striking, 

 but it is amongst the least desirable of thorns. 



Closely allied to C. sanguinea is C. DAHURICA, Koehne, also with branches 

 of a deep brown-purple, but its leaves are smaller (rarely 2 ins. long), scarcely 

 or only finely lobed, almost smooth. Fruit smaller, j to ^ in. long, orange-red. 



Native of S.E. Siberia and Amurland, and, like many shrubs and trees of 

 that region, starts early into growth. At Kew it blossoms at the end of April 

 and early in May. 



Occasionally seen in cultivation also is C. MAXIMOWICZII, C. K. Schneider 

 (C. sanguinea var. villosa, Maximowicz), a species of the sanguinea group, but 

 very distinct in the bristly hairy flower-stalks, calyx, and young fruits the last 

 smooth and red when ripe. Amurland, N. Manchuria, etc. 



C. SINAICA, Boissier. MT. SINAI THORN. 



(C. maroccana, Lindley, Bot. Reg., t. 1855.) 



A tree up to 35 or 40 ft. high, of sturdy habit ; young shoots at first downy, 

 the barren ones becoming more or less smooth by the end of the season, and 

 dark coloured. Leaves wedge-shaped at the base ; i to 2 ins. long, from 

 \ to 2j ins. wide ; varying in outline from narrowly obovate with three small, 

 terminal lobes, to deeply five-lobed with two pointed, oblong, sparsely toothed 

 or entire lobes at each side, and a terminal one ; quite smooth on both sides ; 

 stalk up to -| in. long. Flowers white, fragrant, f in. across ; produced during 

 early June in corymbs of twelve to fifteen blossoms ; calyx and flower-stalks 

 sparsely and loosely downy ; stamens twenty. Fruit globular, yellow or 

 yellowish red, | in. diameter, smooth. 



Native of Sinai and parts of the Orient; introduced in 1822; at present 

 very rare in cultivation, but represented in the Kew collection. It belongs to 

 the same group as Azarolus and orientalis, but is distinguished by the absence 

 of down on leaf and fruit. In this country it is only armed with a few short, 

 stout spines, about \ in. long. 



C. SPATHULATA, Michaux. 



(C. microcarpa, Lindley, Bot. Reg., t. 1846.) 



A shrub or small tree, with a slender trunk and spreading branches ; young 

 shoots smooth or soon becoming so, and reddish brown ; thorns either 

 absent or few. Leaves spoon-shaped, diamond-shaped, or obovate ; often very 

 distinctly three-lobed, the lobes coarsely round-toothed ; apex blunt, the 

 base narrowing to a long thin strip each side of the stalk ; often with scattered 

 down on both surfaces when young ; the stalk, although apparently long, is 

 really very short, owing to the extension of the blade in a narrow wing down
