mens are Triticum (Agropyrum) junceum ; it has been also reported 

 from Paignton and Goodrington sands in the Torquay district. 

 Sir Joseph Hooker, in his Student's Flora, does not extend the 

 distribution of the species to Devon, and Mr. Moyle Eogers has 

 closely searched the Exmouth station and Dawlish Warren for 

 this rare grass, and concludes that it is now absent from South 

 Devon ; recent observations, however, in other parts justify its 

 retention in the county flora." Also, in the addenda to the same 

 History (p. 130), I wrote, for the Honiton botanical district, which 

 includes Exmouth : " Elymus arenarius L. (still found in an old 

 station)." Of my own collecting I have specimens from Exmouth 

 in 1905 and 1906.— W. P. Hiern. 



Potamogeton Friesii Eupr. in Caithness. — Mr. G. Lillie has 

 sent me a box of specimens gathered from Achkislock (or Loch 

 Stemster), among which is a small example of the above species; 

 it was growing with P. perfoliatus L., P. alpinus Balb., and 

 Utricularia major Schmid. (neglecta Lehin.). It is recorded for 

 the Outer Hebrides ! Orkney ! and then not till Dumbarton ! 

 In Sweden it extends north to Gefleborgs Ian, but does not seem 

 to reach Nordland. In Finland it is rare, is recorded by Hjelt 

 (Consp. Fl. Fenn. p. 541, 1895) from Aland and Karelia onegensis, 

 and I have a specimen from Dr. Kihlman from " Shungii," in the 

 same province, and have seen it in the Vienna Herbarium from 

 "Lake Norstrask, 1875, E. Hult and J. Tickham"— this is about 

 66° 59' N. lat. ; and in Eussia to Archangel, ex Herder. I have it 

 also for the Faroes. One of the earliest British specimens I 

 have seen is in the De Candolle herbarium, " Notts, 1833, Jowitt 

 herb." — Arthur Bennett. 



Melampyrum pratense L. var. hians Druce. — A few days 

 ago, at the beginning of July, I found this well-marked variety, with 

 its golden-yellow flowers and open corolla, growing in the Downton 

 Gorge, near Wigmore, North Herefordshire. It is alluded to in 

 the Herefordshire Flora as a yellow variety of the common Cow- 

 wheat, but, as far as I know, it has not been published as a 

 Herefordshire plant under its own name. I have also found it 

 growing at Aira Force, in Cumberland. The picturesque wild 

 rocky gorge formed by the river Teme at Downton, cutting 

 through the Silurian rocks, is well wooded with fine specimens of 

 oak, ash, wych elm, and large trees of Tilia platyphyllos, which, 

 I have no doubt, is native here as well as in South Herefordshire, 

 in the Wye Gorge. — Eleonora Armitage. 



Damasonium Alisma Mill.— The following interesting note 

 occurs in a paper by Mr. Bennett on aquatic plants, mainly con- 

 cerned with Scottish plants, which is reprinted in Trans. Bot. Soc. 

 Edinb. xxvi. 27 (1913), from the Scottish Botanical Revieiv, 1912, 

 p. 23. Mr. Bennett watched Damasonium in a pond on Mitcham 

 Common through the summer of 1887. "In April it was the 

 form (jraminifolium Gliick ; in May it began to make itself into 

 the form spat hula turn Gliick ; at the end of June it had become 

 the form natans Gliick; flowered through July and part of August;
