8. asper (Hoffm.) ) haps S. oleraceus is the most frequent. 



S. arvensis (Linn.) — Cultivated fields east side of lower lake. 



Crepis virens (Linn.) — Rather a rare plant, but it was observed at 

 both Upper and Lower Erne. 



C.paludosa (Moench.) — Frequent about the west side of the lower 

 lake. 



Sieracium pilosella (Linn.) — Devenish, &c., but not common. 



S. iricum (Fries.) ? — Common on the limestone cliffs of Shean at 

 Pollaphuca. The flowers on my specimens are not expanded. 



JS. umhellatum (Linn.) — On the north end of Isle Namanfin in the 

 lower lake ; among the stones on inundated ground, the roots 

 forming a dense matted sod some yards square ; from this the 

 stems grow thickly, and rise about one foot high. A few scat- 

 tered specimens about ten yards away grow to twice that height. 

 Where the plant grew thickly, it had a very puzzling appear- 

 ance, not being in flower. When dried, the flowerless stems 

 have a slight resemblance to Inula salicina. Living specimens 

 brought home are expected to flower this season, but a careful 

 examination leaves little doubt that the plant is S. umhellatum.^ 

 If the living plants flower, all doubt will at once be removed.
