Page II. Under Gymnosfomum curmrostrum add Dicranum hyperloreum. 

 Engl. Bot. t. 2552 ? 



Page 38. We ought to have observed under Dicranum varium that the- 

 Bryum pus/Hum of Dickson proves to he only this plant ; and it is only 

 upon the authority of Mr. Dickson's specimens that Trichostomum pu-> 

 silhim Hed T . (Didymodori) is considered a British native. That plant 

 must therefore be excluded from the British Flora. The English Bo- 

 tany figures are taken from foreign specimens. 



^PsLge 59. Under Dicranum heteromallum read Dicranum interruptum. 

 Engl. Bot. t. 2508. 



Page 61, line 20, for n. 19, rend it. 119. 



Page 6 1 , line 34, for capsule oblong, read capsule ovate. 



Page 62. Under Trichostomum polyphylhim add as a synonym Encalypta 

 crispata. Hedw. Sp. Muse. t. 10. f. 1 9. Upon the authority of spe- 

 cimens which we have received from Dr. Swartz, as well as from a 

 comparison with the figure and description, we are satisfied that Enca- 

 lypta crispata of Hedvvig is only our Trichostomum polyphyUum ; and we 

 have received it not only from the Cape of Good Hope, but also from, 

 the Canary Islands and from the Pyrenees. 



Page 64. We have received plants of Leucodon Canariense (Schwaegri^ 

 chen) from our late lamented friend Professor Schmidt of Norway, 

 which he gathered in the Canary Islands j and we can safely assert that 

 it does not belong to this genus ; so that the Leucodon sciurtides is the 

 only species of the genus hitherto discovered, and it consequently 

 ought to have no specific character. 



Page 6?. Under Didymodon rigidulum add as a synonym Trichostomum It- 

 nearc. Engl. Bot. t. 1598. 



Page 70. Under the genus ZYGODON, read We have lately had the oppor- 

 tunity of examining the peristome of this curious moss, and of con- 

 firming the observations of our friend Mr. Templeton relative to the 

 structure of its teeth. There are filiform processes arising from the 

 sides of the larger teeth , exactly as in most of the Orthotricha. 

 Page 83. After the description of Fontinalis squamosa, read We have never 

 seen F. antipijretica otherwise than in standing waters, or those which 

 had a very slow motion, whilst F. squamosa we have constantly found 

 in mountain streams, where the motion of the water was considerable* 

 In Lough Bray F. antipyretica only is found, and in the stream which 

 issues from it and tumbles down the steep side of the mountain, only 

 JV squamosa >. yet they both fructify in their situations,
