me all he could in the way of information. Do’ any authentic 
specimens survive anywhere? I am confirmed in my op nion that 
the Avon Valley grass is a hybrid, since a strong patch in my 
garden with sixty to eighty spikes this summer proved perfectly 
sterile—Epwarp F, Linton. 
Acrosorsus Wirsont (Tayl.) Nees 1x Scornanp. — During the 
first week of November I found this very rare hepatic, with young 
fruit, in the ravine of Resipol Burn, Sunart, West Inverness. It 
was creeping among Hymenophyllum unilaterale, EKurhynchium myo- 
suroides, Lejeunea serpyllifolia, and Metzgeria conjugata, on the stem 
fatree. Mr. W.H. Pearson, to whom I sent as ecimen, mentions 
that is the finest which he has seen of this species. It is doubtfully 
recorded by Mr. Stabler in his Hepatice and Musci of Westmoreland ; 
otherwise it has only been previously found in Europe in the south- 
west of Ireland, where it does not appear to have been met with for 
many years.—Symers M. Macvicar.

formation of which is sandstone.—Symers M. Macvicar. 
Soranum Rostratum Dunal iw Brrrar.— It may be worth while 
to put on record the appearance of this prickly North American 
species in three widely separated localities in Britain, whence it has 
been received at the Royal Botanic Garden, Edinburgh, for identifi- 
the plant having since died without setting seed, it is not likely to 
reappear. The Kentish plant has, however, produced good seed, 
some of which I understand has been sown in a ‘ secret place.” 
am not aware that more than a single plant was observed at each 
of the stations. It would be interesting to know by what means 
this native of the plains of Nebraska to Texas has been introduced.

Porentiixa supina L. 1x Hast Kenr.—During a day’s botanizing 
at Sandwich last August with three local botanists, this plant was 
found on Stonar Beach in some quantity, and apparently well

has been introduced with ballast.—J. F. JEFFREY,
