Hieracium heierophylhini, ii. 961. Mr. Bladon has ventured on 

 the very bold task of describing a British species under this 

 name : Mr. Bladon does not state in what part of the kingdom 

 it is found : neither has he stated in what characters the new 

 species differs from H. umbellatum, as Mr. Backhouse ob- 

 serves (Phytol. ii. 1022), but Mr. Watson, who has seen spe- 

 cimens from Mr. Bladon, informs me that he considers the 

 two plants quite distinct. 



Ph alar is par ado xa^ ii. 961, was found in July last, by Mr. James 

 Hussey, in a field near Swanage, Dorsetshire, and by some 

 error reported in the September number of the ' London 

 Journal of Botany ' as Phalaris utriculata, of Linneus, now 

 Alopecurus utriculatus, a very different plant in generic cha- 

 racters, although curiously similar in general aspect. 



Polygala depressa, ii. 966. Dr. Bromfield, who introduces this 

 plant to the readers of the ' Phytologist ' as found by himself 

 on Bleakdown, in the Isle of Wight, has ascertained it to be 

 Wenderoth's species, and also to be identical with the P. ser- 

 pyllacea of Weihe ; but he is disposed to regard it as a mere 

 variety of Polygala depressa, although a variety not previously 

 noticed as British. 



Asplenium germanicum^ ii. 974. Mr. H. Wilson has found this 

 exceedingly rare fern near Lanrwst, in North Wales. 



JJdora canadensis? ii. 1050. This plant, which has received^ 

 multiplicity of names, and of which the nomenclature is still 

 unsettled, was discovered in July last, by Miss M. Kirby, 

 growing in great abundance in three reservoirs, by the canal 

 in the neighbourhood of Market Harborough, in Leicester- 

 shire : when first observed, flower-buds were beginning to 

 appear, and throughout August flowers were produced abun- 

 dantly, but unfortunately those gathered proved all to be 

 females, the plant being dioecious. The stems are entirely 

 submersed, a foot or more in length, growing horizontally and 

 branched ; the leaves are three or rarely four in a whorl, ob- 

 scurely egg-shaped, embracing the stem, entire ; the flower-
