CORRECTIONS, &c. 



17, line 3, from the bottom, for Knight read M'Knight. 



45, for 305 read 303. 



47, line 10, from the bottom, for auricornus read auricomus.

56. There has been a mistake in setting the types for the 

 Table at the top of the page. The " Low " and " High 

 Grounds " ought to have been represented as meeting in 

 the Median region, whereas this region is made to appear as 

 if exclusively belonging to the Low Grounds* (See page 

 65, near the bottom.) The word " Plains," should be in- 

 serted in the blank space opposite " Clematis Vitalba," in 

 the same table, which is unintelligible without these cor- 

 rections. 



56, line 13, from the bottom, for will read may. 



88, line 7 ,for counties read countries. 



90, Under Salix insert " Habenaria chlorantha. Kent." (Re- 

 cently discovered by Dr. Lindley, and will probably be 

 found in other counties. It is likewise omitted in the Ap- 

 pendix.) 



116. Ranunculus alpestris should be referred to the subalpine 

 region doubtfully, because the precise station is not now 

 known.

 unnecessary addition of " to 0°." 



119. Cochlearia grcenlandica probably rises much above the 

 plains. 



120. Sisymbrium lrio. " Pla." is omitted. 



124. Stellaria nemorum begins in latitude 53 or (52). 



125. Cerastium latifolium is joined with " aquaticum "' instead 

 of with " alpinum." 



126. Tilia parvifolia perhaps reaches the upland region. 

 130. Orobus niger, " Upl. ? " is omitted. 



ISO. O. sylvaticus, " Pla" is omitted,
