Ornithogalum umbellatum L. Wood above Old Bridge of Don 

 (i860, A. Ogston) ; an escape. 



* Allium oleraceum L. Is recorded in Guide from Arbuthnot, 



as introduced ; but it is abundant on a wooded bank below 

 Stone of Morphie in St. Cyrus, under conditions that cer- 

 tainly seem exceedingly like those of a native plant ; hence 

 from my own observations I am disposed to consider it as 

 native there at least. 



Graminace.e. 



* Digitaria sanguinalis Scop. Is recorded by Dickie as once 



found on the Inch. Introduced in ballast. 



* Setaria viridis Beauv. Has the same record ; and Mr. Roy has 



also notes of its occurrence, as also of the occurrence of 



Setaria verticillata Beauv. 



Phalaris canadensis L. Is very frequently to be found near the 

 town on rubbish-heaps, in sand-pits, on the Inch, and else- 

 where as an accidental introduction, owing to its use as a 

 food for birds. It nowhere holds its own. 



* Alopecurus agrestis L. Dickie records it at Kettock's Mill, and 



on the Inch. 

 Polypogon monspeliensis Desf. Has been .obtained by Mr. 

 Roy from Stonehaven ; probably a ballast plant. 



* Avena flavescens L. Is rather doubtfully native ; its appear- 



ances are more such as may be accounted for by introduc- 

 tions. 

 Avena sativa & A. strigosa Schreb. May both be found by 

 roadsides and near houses, as escapes from cultivation, 

 but they are never permanent. 



* Glyceria aquatica Sm. Is recorded at Breda and thence down 



the Don, in Guide ; also at Gight (i860, A. Ogston). 



* Bromus arvensis L., B. secalinus L., & B. commutatus Schrad., 



all of which occur in grass fields and by roadsides and on 

 river banks, seem to have been introduced into the district 

 among agricultural seeds. 

 Bromus rubens L. Has been sent me by Mr. W. Tait from 

 Inverurie, gathered on the ground where esparto grass is 

 spread when imported. 



* Hordeum murinum L. Has doubtful claims to be considered 



native, but is included among our native plants in the
