following interesting alien and casual grasses recently found 
in the neighbourhood of Edinburgh, where their presence 
was Clearly due to casting out of refuse from foreign grain. 
New records for Britain are indicated by a star. 
*4dvena barbata, Brot. (a native of Asia Minor, Arabia, 
and the Mediterranean region); Apera intermedia, Hackel 
(first found in 1904 by Drs. Penther and Zederbauer in the 
Erdschias-Dagh, Asia Minor, once since found as a casual 
in England and several times near Edinburgh; it occupies 
a place midway between A. Spica-Venti and A. interrupta) ; 
*Gaudinia fragilis, Beauv. (frequently found here during 
the last four years, probably often mistaken for a form of 
Lolium italicum); Phleum grecum, Boiss. and Heldr. (often 
occurring and in great quantities, with spikes varying from 
four inches to one-eighth of an inch in length); Phalaris 
minor, Retz.; P. cwrulescens, Desf. ; P. intermedia, Bose. ; 
*P. tuberosa, L.; P. paradoxa, L.; *Trisetum pumilum, 
Kunth; *Agropyron triticeum, J. Gertn.; *Ke@leria phle- 
oides, Pers.; *Poa persica, Trin. ; * Bromus japonicus, Thunb. ; 
*B. divaricatus, Rhode (the last named has been placed 
under B. macrostachys, Desf., by several authorities, but 
is a very distinct plant, which seems to deserve specific 
rank). 
Mr Fraser also exhibited specimens of ergotised grains of 
Melica nutans from near Lochan ua Lairige, Perthshire. 
Dr. A. W. BortTHwick exhibited branches and cones of 
Picea rubra. In the year 1869 Mr. William Gorrie read a 
paper to this Society on Abies rubra, and exhibited specimens 
taken from trees grown on the railway bank near Tynehead 
Station in Midlothian. The trees at that time were about 
fifteen years planted, and were from 12 to 18 feet high. 
Some of these trees still remain,and are now about 40 feet 
high, and appear to be still thriving, although damaged to 
some extent by smoke from the passing trains. 
Professor BAYLEY Ba.rour, F.R.S., showed a specimen of 
Polygonum pseudo-dumetorum, H. C. Wats., found in the 
neighbourhood of Edinburgh; also an cld and very fine 
portrait of Linneus.
