each side. Excluding this, the leaves of the flowering shoots are i to I in. 

 long, to f in. wide ; on the barren shoots i to i^ ins. long, nearly as much 

 wide. Flowers white, in. diameter, produced towards the end of June 

 in corymbs i^ ins. across ; stamens sixteen to twenty ; styles two to five. 

 Fruit j^ in. in diameter, globose, coral-red. 



Native of the south and south-eastern United States; introduced in 1806. 

 It ripens its fruits late, not until October, and both they and the leaves remain 

 on the plant until the New Year. This is one of the more tender thorns, and 

 apt to suffer in severe winters. Distinct in its tiny fruits. 



C. STIPULACEA, Loddiges. 



(C. pubescens var. stipulacea, Staff. ; Bot. Mag., t. 8589.) 



A small, usually unarmed tree, probably 1 5 to 20 ft. high ; young shoots 

 greyish at first with loose down, afterwards red-brown and roughish with 

 minute warts. Leaves diamond-shaped, obovate or oval ; wedge-shaped and 

 entire at the base, the upper part pointed and doubly glandular-toothed ; 

 \\ to 4 ins. long, f to 2 ins. wide ; usually much larger on the barren shoots 

 and with large glandular-toothed stipules f in. across ; at first slightly downy, 

 afterwards smooth and dark green above ; grey, dull, and persistently downy 

 on the chief veins beneath ; stalk about ^ in. long. Flowers white, f in. 

 across, produced in June in corymbs 2 to 2^ ins. across ; flower-stalks and 

 calyx woolly, calyx-lobes slightly toothed or entire ; stamens fifteen to twenty ; 

 styles two or three. Fruit yellowish, dotted, f in. long, globose, persisting 

 on the tree a long time. 



Native of elevated regions in Mexico ; introduced by A. B. Lambert 

 in 1829, and interesting as one of the few trees from that country that are 

 hardy with us. It retains its leaves usually until the New Year. Sometimes 

 known in gardens as C. mexicana, De Candolle. (See also C. Carrierei.) 



C. SUCCULENTA, Link. 



A tree up to 20 ft. high, with smooth branchlets, becoming purplish brown 

 by the end of the season ; thorns i^ to 2 ins. long. Leaves roundish obovate, 

 2 to 3 ins. long, i \ to 27? ins. wide, broadly wedge-shaped at the base, abruptly 

 pointed, more or less lobed towards the apex, sharply toothed, at first downy 

 beneath, soon smooth ; dark green and glossy above ; veins parallel, in four 

 to seven pairs. Flowers white, f in. across, produced in early June in 

 rounded corymbs, 3 ins. or more across ; flower-stalks hairy, and calyx 

 usually so ; stamens fifteen to twenty, anthers pink ; styles two or three ; 

 fruit globose, bright red, ^ in. diameter. 



Native of Eastern N. America, and a close ally of C. tomentosa. It has 

 the same deep longitudinal pits in the seeds (nutlets), but differs in the midrib 

 and veins of the leaf being more deeply sunken on the upper side, and in the 

 fruit being globose rather than oval, and of a deeper, brighter red. It is 

 also a more vigorous and thorny tree. Although it was known in cultivation 

 in the early nineteenth century, it appears to have been lost sight of until the 

 last two decades. 



C. TANACETIFOLIA, Persoon. TANSY-LEAVED THORN. 



(Bot. Reg., t. 1884.) 



A small, mostly unarmed tree up to 35 ft. high, with erect branches and a 

 trunk occasionally 5 ft. in girth ; young shoots clothed with a thick grey wool, 

 which persists partially on year-old snoots. Leaves i to 2 ins. long, nearly or 

 quite as wide, tapered at the base ; obovate or diamond-shaped in outline, but
