Algeria, J. Lefebre, 1861. 

 Var ^ majus, foliis amplibus, serratis, utrinque pubescentibus, 



C. Oxyacantha. Fing. , 

 Hampstead Heath, J. Boswell Syme, 1864. 



The leaves of the typical form of this species are roundish or obovate, 

 more or less serrate, and without hairs, the peduncles, calyx and germen 

 being also glabrous. A specimen gathered near Lyon by M. Jordan agrees 

 with the type very well except that the leaves are larger and not at all serrate. 

 An English specimen sent from Kew by Mr. Baker only differs in the leaves 

 being occasionally very slightly hairy on the midrib beneath, whilst another 

 approaches more closely to variety majus. 



The variety majus has the leaves two or three times larger than in the 

 type, more elongated and somewhat hairy on both sides. 



ii. C. MONOGYNA. Jacq,^ Fingerhuth. 



C. spinosa, Miis serratis, 3-5 lobatis basi cum petiolis subtusque in nervis subciliatis 

 nervis divaricentibus, floribus corymbosis monogynis stylo recto, calycibus glabris vel 

 aliquando subciliatis, laciniis ovatis reflexis, apice obtusis, peduj.culis glabris, fructibus 

 globosis vel oblongo- ovatis, nucleo uno incluso.

Isle of Man, C. P. Hobkirk, August 1866. 

 Var. y3 urceolata. Fructibus urceolatis, iongioribus bis quam latis. 



Near Thirsk, J. G. Baker, August, 1865. 



This species is I believe pretty generally distributed throughout 

 England. It varies somewhat in the size and serration of the leaves, and in 

 the depth of the lobes, but otherwise so far as my specimens are to be relied 

 on may easily be recognised by its constantly glabrous peduncles and calyx, 

 the latter having occasionally a few scattered hairs upon it. This is the 

 plant distributed by Professor H, Yan Heurck on his Herbier des plantes 

 rares ou critiques de la Belgique, Fasc. Ill, iN'o. 140," gathered by M. A. 

 Wesmael, at Mons, in 1864. 



urceolata, as its name indicates has the fruit urceolate, and at least 

 twice as long as broad, with leaves deeply divided, and not so generally 

 serrated as in the type. 



iii. C. KTRTOSTYLA. Fing. G. monogyna, Auct. G. calycina, Petermann (?) 



C. spinosa, foliis utrinque glabris vel subtus nervis ciliatis, plerumque serratis, 

 3-5 lobatis, nervis divarigentibus, floribus corymbosis monogynis, stylo deflexo (?) 

 calycibus pedunculisque hirsutis et etiam germinis, laciniis oblongis acuminatis, apice 

 obtusis, patentibus vel aliquando reflexis, fructibus sub-globosis nucleo uno.
