Hieracium ccesiimi, Fries. Canlochen Glen, White Water, &c. 



Hieraciiim rupestre, Allioni, Koch and Fries. A new and interest- 

 ing species, which seems to be unquestionably the above-mentioned 

 plant. Cairntoul. 



Hieracium atrattim, Fries. Maintains the same distinct character 

 on Loch Esk Craig, Clova, Lochnagar, Canlochen, Garachary and 

 Ben-na-bourd. 



Hieracium pallidum^ Fries, var. ? Near to H. persicifolium, Fries: 

 a curious and interesting plant. 



Hieracium alpinum, typical. On Lochnagar and Ben-na-bourd ? 

 Exactly the same as the plant from Glaramara, Cumberland. It is 

 covered all over with long, shaggy, white silk, and has broad-based, 

 short involucral scales. Its ligules are strongly ciliated. Under cul- 

 tivation this plant becomes still less like H. raelanocephalum. 



Hieracium ? Allied to H. alpinum, but differs in several 



respects, and seems to keep its characters. Ben-na-bourd and ravine 

 of the Garachary. 



Hieracium nigrescens. On granite rocks almost exclusively. 



Port CiBsia. Very abundant .and fine in a ravine in Canlochen 

 Glen. 



Poa Balfourii ? Along with the previous one. I have not the 

 slightest hesitation in pronouncing my P. Balfourii ? specifically dis- 

 tinct from P. csesia, with which it grows, but retains a perfectly dif- 

 ferent character. The two species may be described as follows . — . 



P. ccesia. Plant four to six, sometimes eight, inches high, erect, 

 rigid, bluish green or slightly tinged with purple in the florets. 

 Branchlets of the panicle spreading rigidly at right angles when 

 growing. Florets acute, free. Leaves broad and short ; joints 

 covered and confined to the lower part of the stem. Ligules very 

 long. P. csesia loses its character by pressing. 



P. Balfourii ? Plant six to nine inches high, erect, rather slender, 

 puipiish green, not at all csesious. Spike often rather lax. Branch- 

 lets spreading, but not at all rigid. Florets ovate, slightly webbed. 

 Uppermost joint one-third from base; occasionally all the joints con- 

 cealed. Leaves narrower than in the former species. Ligules very 

 long. 



Both the species appear to form tufts in the same way. In exa- 

 mining the latter I never thought of its being P. Balfourii, from the 

 root of that species being described as creeping, and the ligules simi- 

 lar to those of P. montana, whereas they are as dissimilar as those of 

 P. annua and P. nemoralis. P. csesia has not the remotest connexion
