88 ANNALS OF SCOTTISH NATURAL HISTORY 



TARAXACUM OFFICINALE, Web. Common on roadsides and walls, 

 extending to the dunes ; a form that occurs, though scarce, on 

 the latter, with brick-red achenes, is under examination. 



Var. c. palustre (DC.) Marshy ground on north-east shore, 



rare. 



Var. d. udum (Jord.) ? Wet rocky ledges, Kenavara; appears 

 to agree with plants so named. (A similar form is 

 common on this coast among wet rocks.) 



SONCHUS ASPER, Hoffm. Common ; sides of fields and waste places. 

 LOBELIA DORTMANNA, L. Rather common in the more peaty lochs. 



CAMPANULA ROTUNDIFOLIA, Z. Locally common ; Kenavara, 

 Ballyphetrish, etc. 



VACCINIUM MYRTILLUS, L. Apparently rare. 



CALLUNA ERICA, DC.; ERICA TETRALIX, L.; E. CINEREA, L. All 

 the heaths must be classed among the " common " plants of 

 Tiree, the first especially so ; but being always prostrate, and 

 not more than two to three inches in height, they are incon- 

 spicuous so much so that the general visitor might think that 

 they are not to be found on the island. The Calluna is much 

 the most common, and is not confined to the central moorish 

 ground as the others appear to be. 



ARMERIA MARITIMA, Willd. Very common; shore rocks, salt 

 marshes, and sand dunes. 



PRIMULA ACAULIS, L. Locally common ; Kenavara, Cliad, Salum. 

 LYSIMACHIA NEMORUM, L. Rare. 



GLAUX MARITIMA, L. Common in salt marshes and on muddy 

 shores, more rarely in sandy places. 



ANAGALLIS TENELLA, L. A very common and characteristic plant 



of Tiree. 

 CENTUNCULUS MINIMUS, L. Only seen on a wet bank on the shore 



at Rudh-an-Sgoir Mhoir. 



SAMOLUS VALERANDI, L. Common in several places ; Fhaodhail, 

 Loch-na-Mointeich, etc. 



ERYTHR^A CENTAURIUM, Pers. Rather common ; Barrapol, etc. 



Var. capitata, Koch (teste Ar. Bennett). Hynish Bay sands, 

 Kenavara Head. 



GENTIANA CAMPESTRIS, L. Rare ? ; seen only near Scarinish. 



MENYANTHES TRIFOLIATA, L. Common, but not generally in 

 quantity. 



LYCOPSIS ARVENSIS, L. Common at the sides of sandy cultivated 

 fields and on roadsides near cottages, but nowhere with the 

 appearance of being native.
