118 PROCEEDINGS OP THE 



July 1st, 1879. 



Mr. W. J. Millisran in the chair. 



Mr. Ewing exhibited an abnormal specimen of Caltha palustris, 

 and reported the finding of the Adder's tongue — Ophioglossum 

 vulgatum — at Milngavie. 



Mr. F. G. Binnie exhibited specimens of Planorbis complanatus, 

 Lin., collected by Mr. J. J. King, in Maxwelltown Loch, Dum- 

 fries, where it is abundant, and is the second known Scottish 

 locality for the species. Mr. Haddin recorded it for Loch-end 

 Loch, Edinburgh (Proceedings, Vol. I., p. 247); and Mr. David 

 Robertson, F.L S., F.G.S., writing more recently on its occurrence 

 in the latter locality (Proceedings, Yol. III., p. 173), says — "It is 

 somewhat singular that, while this shell is so plentiful all over 

 England, Wales, and Ireland, the small patch of water near 

 Edinburgh, known as Loch-end Loch, is its only known locality in 

 Scotland." He adds further that the loch is being filled up through 

 the emptying of the town refuse into it. Here it will probably 

 soon be extinct. Mr. King's discovery will, however, enable it to 

 retain its place in the Scottish Fauna. 



Mr. Turner exhibited a large number of rare plants recently 

 collected by himself. Among these may be mentioned — 



Doronicum plan taginei im. 

 Tulipa sylvestris. 

 Meconopsis cambrica. 

 Scrophula/ria vemalis. 

 Arum italicum. 



Hippophaae rhamnoides. 

 Papaver argemone. 

 Ligusticum scoticum. 

 Montia fon tana. 

 Osmunda regalis. 



Mr. A. S. Wilson then read a paper, entitled " Unwelcome 

 Flower Guests," in which he compared a cleistogamous flower, 

 such as those produced by the violet — the type of a self-fertilized 

 flower — with ordinary flowers, and said that the comparison 

 brought out that ordinary conspicuous flowers, in addition to the 

 means of attracting certain classes of flying insects, were also pro- 

 vided with structures, the object of which was to prevent the 

 access of small crawling and creeping insects, which could do no 

 good in the way of transferring pollen, and thus effecting cross- 

 fertilization. These obstructions might be ranged under the follow- 

 ing heads : — 1st, isolation of the flower-stalk in water; 2nd, viscid 

 secretion on flower-stalk ; 3rd, prickles and downward-pointing hairs
