CRAT^EGUS 427 



Goodenough's herbarium, dated 1781, is preserved at Kew, and is no doubt 

 authentic, as it is ascribed to Solander, Alton's coadjutor ; this differs from the 

 trees now cultivated at Kew by having about twenty stamens to each flower, 

 and in being perfectly glabrous in flower and leaf. The species is of historical 

 interest, and as. being the type of a considerable group of thorns from the south- 

 eastern United States ; but in its few flowers and sparely borne, dull-coloured 

 fruits it is one of the least ornamental. 



C. FONTANESIANA, Steudel. 

 (C. Crus-galli var. Fontanesiana, Wtnzig.} 



Of obscure origin, this thorn belongs apparently to the Crus-galli group, and 

 is probably a hybrid between that species and C. prunifolia. It has dark, 

 purplish brown branchlets with thorns up to I in. long. Leaves narrowly 

 obovate, 2 to 4 ins. long, f to i^ ins. wide ; pointed and toothed at the upper 

 part ; tapered, and entire below ; smooth and dark glossy green. Corymbs 

 many-flowered, 2 to 3 ins. across, with downy stalks. Flowers white, \ in. 

 across ; stamens fifteen to eighteen. Fruit roundish oval, dull red, \ in. long. 

 The downy flower-stalks are like those of C. prunifolia, but the longer, 

 narrower leaves, and dark young shoots are quite distinct. It is probably of 

 garden origin, and has been known in cultivation over one hundred years. 



C. HETEROPHYLLA, Fltigge. 



A tree up to 20 ft. high, forming a round dense head of branches ; young 

 shoots smooth ; not, or but little, armed. Leaves of two distinct types, viz. 

 (i) those of the barren shoots : diamond-shaped, tapered and entire at the base, 

 the upper part sharply pointed, deeply lobed (after the fashion of monogyna), 

 the lobes sharply and irregularly toothed ; i^ to 3 ins. long, \\ to 2^ ins. wide ; 

 stalk \ to | in. long ; (2) those of the flowering shoots : much smaller, oblong, 

 obovate or oval, sometimes entire or with a few teeth at the apex only, some- 

 times the upper leaves of the shoot conspicuously three-lobed at the apex ; 

 i to \\ ins. long, \ to f in. wide. All the leave's are glossy dark green and 

 quite smooth. There are large, coarsely toothed stipules on the barren 

 shoots, none on the flowering ones. Flowers white, f in across, borne during 

 May and June in corymbs 2 to 3 ins. across ; flower-stalks and calyx smooth ; 

 stamens fifteen to twenty, styles solitary. Fruit bright red, slenderly oval, 

 \ to in. long. 



Native of Armenia ; cultivated since the beginning of the nmeteeth century ; 

 not now very frequently seen, although there are several splendid examples in 

 the fine collection of thorns in the Bath Botanic Garden. It is a beautiful 

 thorn of the Oxyacantha group, bearing its large flowers and bright fruits 

 freely. It is also one of the most distinct by reason of its variously shaped 

 leaves, its long narrow fruits, and the absence of down from the younger parts. 



C. KOROLKOWI, Regel. 



(C. tatarica, Hort.~) 



A tree up to 25 ft. high, forming a dense, heavy, very leafy head of 

 branches. It is really a very vigorous, large-leaved form of C. pinnatifida, 

 and has been named C. p. var. major, N. R. Brown. The leaves are harder 

 and thicker than in C. pinnatifida, and not so flat ; 3 to 6 ins. long and nearly 

 as much wide ; the lobes not so deep but broader ; except for a slight hairiness 

 along the midrib and larger veins, they are smooth. They are of a rich dark 

 lustrous green, the midrib, veins, and young wood tinged with red. Flowers
