176 ANNALS OF SCOTTISH NATURAL HISTORY 



C. riparia, Curtis. Observed only at the mouth of the Philorth, in 



the parishes of Rathen and Fraserburgh. 

 Pltalaris canariensis, L. 93, here and there as a casual. 



Avena strigosa, Schreb., and A. fatua, L. Both occurred here and 

 there as weeds among cereals in both 93 and 94. 



Catabrosa aquatica, Beauv. Was observed only in Rathen. 



Briza media, L. Appears to be scarce. I found it only in one 

 locality, in Slains. 



Glyceria aquatica, Sm. 93*, grows near the mouth of the Burn of 

 Auchmacoy in Ellon, beside both the burn and the Ythan. Its 

 distribution in Scotland leads to a suspicion that it is probably 

 not indigenous in Aberdeenshire, though well established. 



Festitca sciuroides, Roth. Very scarce in 93, though seen in three 



parishes. 

 F. elatior, L., \ax.pratensis, Huds. 93'% here and there in Slains 



and Ellon. 



Bromus secalinus, L. 93*, rare, and possibly introduced among 



grass seeds. 



Brachy podium gracile, Beauv. Very local ; coast of Slains and 

 Cruden, and at Gight in Fyvie. 



Agropyrqn repcns, Beauv., var. barbatum, Duval Jouve. 93* and 

 94*, common in many places. 



A. pungens, Roem. and Schult. 93*, on sandy coasts in various 

 localities. 



Junipcnts nana, Willd. 93'% on cliffs on coasts of Slains and 

 Cruden. J. communis has been recorded from Peterhead and 

 Aberdour, but probably should be referred toy. nana. 



Polystichurn Lonchitis, Roth. I have seen a dried specimen from 



Aberdour. 

 Equisetum palustre, Z., var. polystachyum, auct. 93*, plentiful in one 



locality on the Links of St. Fergus. 



Lycopodium. This genus appears to be remarkably scarce in Buchan. 

 The only example I observed was a single small plant of L. 

 clavatuin in Monquhitter. Both L. clavatitm and L. Sehigo 

 have been recorded from the district previously. 



Selaginella setaginoidcs, Gray. Locally common, though stunted, on 

 the bar that separates the Loch of Strathbeg from the sea. 



Chara aspera, Willd. 93*, Loch of Strathbeg. 

 C. vulgaris, L. 93*, Canal of St. Fergus. 



A few critical forms still await determination, and may 

 form the subject of a later note.
