Jungermanni(S, some of which were very rare^ A lady had ga- 

 thered 50 species oi Jungermanni(S within five miles of Dumfries^ 

 and these are now in the herbarium of Mr. J. H. Martin. He 

 frequently found white varieties of Calluna vulgaris. He also ex- 

 hibited two specimens of Eriophorum vaginatum, showing the ef- 

 fect of the dry soil in stunting the growth, and vice versa. Mr. 

 Brown, in conclusion, gave a list of 100 plants found growing on 

 the dock wall of Dumfries, from the foot of Assembly Street to 

 the Castle dykes, a distance of about half a mile. The paper was 

 illustrated by a large collection of plants gathered. 



3. Sketch of a botanical excursion to the neighbourhood of 

 Moffat, on July 9th, 1859, by John Sadler, Esq., F.B.S.E. ; but 

 as this paper will appear in exienso in the columns of the ' Phy- 

 tologist,' we would refer our readers to it. 



The Secretary noticed the following donation to the Library : 

 'Rambles among the Wild Flowers,' by John Sadler, F.B.S.E., 

 from the Author. The Society then adjourned. 



THIRSK NATURAL HISTORY SOCIETY. 

 Botanical Exchange Club. 



The monthly meeting of this Society was held on the evening 

 of Monday, the 5th of February. Mrs. Alban Atwood, of Knay- 

 ton, near Thirsk, was admitted a member of the Exchange Club. 

 Mr. J. G. Baker announced the receipt of a parcel from the Rev. 

 W. R. Crotch, and communicated the following notices : — 



" Papaver Lecoguii, Lamotte, in Mem. Acad. Clermont, 1851 ; 

 Boreau, PL Cent. edit. 3, p. 30 ; Crepin, Notes Belg. p. 7. Mr. A. 

 G. More sends an example of this plant from cultivated fields at 

 Bembridge, in the Isle of Wight. Some time ago I gathered a 

 Poppy in the Thirsk neighbourhood, which I suspect to be the 

 same, but I neglected to study it in the living state, and have 

 only a single dried specimen to refer to. It is nearest P. dubium, 

 but in that species the sap is milky-white, whilst in P. Lecoquii 

 it is yellow in colour. The latter is also more robust in growth 

 than dubium, with leaves usually doubly pinnate, with narrow- 

 linear segments. There are three closely allied plants with 

 milky-white sap described by some of the later authors from ad- 

 jacent countries of the Continent, viz. P. collinum, Bogentr., P.
