to be the only author that has mentioned its native country, 

 are near the Hague, near Delft, and in Friseland. 



Doubts have been thrown upon the truly native character 

 of this plant, and also of U. pilulifera. It appears not im- 

 probable that they may both have been introduced into this 

 country at some former time. But as this is uncertain U. Do- 

 dartii has an equal claim to be considered as a native of En- 

 gland with U. pilulifera, which has long been introduced into 

 our lists. 



2. U. pilulifera, Linn. Foliis oppositis, late ovatis cordatisve acuminatis 

 grosse dentatis, stipulis oblongo-ovatis, glomerulis fructiferis globosis 

 pedunculatis, seminibus punctato-tuberculatis. 



U. pilulifera, Linn. Sp. pi. 1395. Eng. Bot. 148. Sm. Eng. Fl. 4. 134. 

 Wallr. Sched. Crit. 488. Reich. Fl. excurs. no. 1105. Koch. Syn. 635. 



Stems erect, bluntly quadrangular. Leaves broadly ovate, 

 usually cordate at the base, the margins deeply cut into large 

 divaricated teeth, much larger than those of U. Dodartii, and 

 on longer and thicker stalks. Stipules oblong-ovate, broader 

 than in the preceding. Fruit stalks very short, scarcely ex- 

 ceeding the diameter of the large globular head. Seed dark 

 brown with numerous darker prominent points, rather opaque. 



Locality, in the counties of Norfolk and Suffolk. 



Owing to the want of English specimens the description 

 has been drawn up from the comparison of two foreign spe- 

 cimens (one No. 22 in Reichenbaclr's Fl. Germ. Exsic. com- 

 municated to that work from Thuringia by Wallroth, the other 

 from Rome, gathered by W. C. Trevelyan, Esq.) with the plate 

 in Eng. Bot. 



The specimen of U. Valearica in the Linnaean Herbarium 

 appears to be nothing more than a larger leaved form of this 

 species, notwithstanding its usually cordate base to the leaves. 

 Both the specimens mentioned above, and also the plant in 

 Smithes Herb, from Hungary, are rather the U. Valearica than 

 the U. pilulifera of Linnaeus. I have never seen specimens 

 with the leaves so decidedly rounded (not at all cordate) at 

 the base as in the original plant of the Linn. Herb. It is 

 much to be wished that botanists resident in the eastern coun- 

 ties would pay attention to these plants, in order that we may 

 obtain information concerning their variations, and also their
