aud on Ben Voirlich, near Ardlui, the Club observed a 

 large quantity of Pteris aquilina, Linn., with fronds all 

 crested. There would be at least an acre of the hillside 

 covered with this fern, and nearly every plant was 

 abnormal. In 1891, and again in 1894, and more 

 especially in 1895, the Club gathered a large quantity 

 of a submerged plant in Lochan Bhe, near Tyndrum. 

 Excellent specimens were obtained, and submitted to 

 eminent botanists, and there was a general concensus 

 of opinion that the plant was Scirpus Jiuitans, Linn. 

 No specimen was found with flower or fruit, and not- 

 withstanding the opinion of eminent botanists, several 

 members of the Club are not convinced that it is S. 

 Jiuitans, and some favour the idea that it is a modified 

 Juncus. 



On loth July 1899, three members of the Club, 

 Mr. Boyd, Dr. Paul, and Mr. Lindsay, visited Ben Avon, 

 a high mountain dividing Banffshire from Aberdeenshire, 

 and gathered many interesting alpine plants, including 

 Saxifraga cccspitosa, Linn. The plants were in full Hower, 

 but none were seen in seed. This is a very interesting 

 find. The plant was discovered by Dr. Paul, and after- 

 wards picked Ijy Mr. Boyd and Mr. Lindsay. 



This Saxifrage is one of the rarest of British alpines. 

 Hooker, in 1821, possessed specimens gathered by G. Don. 

 In 1830, Mr. William M'Nab gathered a single specimen 

 on Beinn a' Bliuird, and it has never been found on this 

 mountain since. In August 1831, Mr. W. Stables 

 gathered it on Ben Avon. In the same year, but 

 probably after August, Mr. John Mackenzie, gardener, 

 Invercauld, gathered it on Ben Avon. Mr. Mackenzie 

 was accompanied by Dr. Martin Bany, who also picked 

 the plant. Dr. Barry, in 1832, again gathered the plant 

 on Ben Avon, and there is no record of the plant having 

 been gathered on J)en Avon since 1832, till Dr. Paul found 

 it in July last. It appears to have been gathered on 

 Ben Nevis by Joseph Woods before 1838, and since 

 that time it was not recorded from Britain till Mr. Boyd 

 discovered it in Glen Spcan in 1886. 



Tlie discovery of this plant on Ben Avon by Dr. Paul, 

 ill -July last, is a most interesting find. 1 have no means
