(Arnofct in Flora Scotica, 1821) (this is probably the Whitemoss), 

 not recently found." Apparently extinct. This species likes open 

 spaces, and it has probably been crowded out. During recent 

 years the conditions of the vegetation of the Whitemoss have 

 altered very considerably, and these changes would form an 

 interesting ecological study. 



Carex teretiuscula Good. "Whitemoss, near Dunning (!)." 

 Plentiful at the west side of the loch. 



Phalaris canariensis T. Has occurred (1907) as a casual near 

 Dunning. 



Glyceria aquatica Wahlb. " Whitemoss Loch, Dunning." 

 Still occurs here ; also plentiful in a marsh south of the village. 



Boa Chaixii Vill. " Has been found at Dunkeld and Birnam. 

 It is, of course, not a native." Kincledie Wood, evidently long 

 established. This grass has now been recorded from a good many 

 places in Britain, and, as Mr. Bennett has pointed out, it is either 

 spreading or has been overlooked. 



Characece. — My gatherings, all from the Whitemoss Loch, 

 were determined for me some considerable time ago by Messrs. 

 H. and J. Groves. Ghara fragilis Desv. — C. aspera var. sub- 

 inermis Kuetz. Not recorded for v.-c. 88 in Fl. Perthsh. — 

 Nitella flexilis var. crassa Braun. — N. opaca Ag. — N. translucens 

 Ag. Not given for v.-c. 88 in Fl. Perthsh. 



SHORT NOTES. 



Aurostis nigra Withering in France. — In April I found a 

 few good specimens of this grass growing with typical A. vulgaris 

 With. (Arr., ed. 3, ii. 131 (1796) ) at the side of a cart-road through 

 an arable field near Carqueiranne, Var, France. Monsieur Emile 

 Jahandiez, who has a good botanical library, believes it has never 

 before been recorded from France — indeed I am unaware if this 

 little known grass has previously been noticed out of England. 

 It is mentioned in Husnot's book on the Grasses of France, 

 Belgium, Switzerland, and the British Isles, but only from a few 

 of the English Midland counties. Since Withering's time it 

 appears to have been overlooked until Mr. J. E. Bagnall re- 

 discovered it near Birmingham, and published an illustrated 

 account of it. in this Journal (1882, 65, t. 227). In 1893 he pointed 

 it out to me in arable fields in Warwickshire, and I was so struck 

 by its appearance that not long afterwards I saw it in Somerset, 

 and I think sent voucher specimens to the Watson Bot. Exch. 

 Club. Here in the south of France it assumes the same rigid 

 habit and the same brown colour. It is taller and more robust 

 than A. vulgaris, with more scabrid panicle and larger spikelets. 

 Now that its known range is so much extended it may prove to 

 have been overlooked elsewhere. — H. Stuart Thompson. 



Cornish Notes for 1912.— Viola epipsila Led. This was 

 found by me at the Holy Well, Roche, v.-c. 2, in 1910, and in
