PROCEEDINGS OF SOCIETIES. 301 



Esq. " Botanical Notes taken on the Rock of Gibraltar." By T. C. Arclicr, 

 Esq. " Report on the Open-air Vegetation at the Royal Botanic Garden." By 

 Mr. M'Nab. Mr. Peacli gave a list of forty-one species of AJgce, collected by 

 Miss Jeffreys in 1861, at tlie Outer Skerries of Whalsey, Shetland, ten of which 

 are additions to Edmouston's list. Mr. Christie exhibited growing flowering 

 plants of what appeared to be Saxifraga granulata, which he stated had been 

 obtained from the bwlblets of plants of S. cernua, collected on Ben Lawers. 

 Professor Balfour remarked that plants of S. cernua from Ben Lawers had 

 been cultivated iu the Botanic Garden for many years, and never changed 

 their normal form. Mr. Sadler thought that, as S. granulata also occui'red on 

 Ben Lawers near where S. cernua grew, it was possible that the two species 

 had been collected by Mr. Christie, and got mixed before planting them in pots. 

 Mr. Sadler exliibited dried specimens of Tupa rhi/nchopetala, a Lobeliaceous 

 plant from Abyssinia, and called attention to the peculiar structure of its 

 stem. 



June 9t7i. — Sir Walter Elliot, President, in the chair. The following com- 

 munications were read: — "Note on the Ipecacuanha Plant." By Dr. Gun- 

 ning, Rio Janeiro. " New and Rare Mosses irom Ben Lawers." By Dr. J. 

 Stirton. Communicated by Mr. Sadler. "Notice of G>*j)«mzas collected on 

 Arthvir's Seat, near Edinburgh." By Mr. Wm. Bell and Mr. J. Sadler. 

 Species of this genus are numei'ous on Arthur's Seat, but most are remarkably 

 limited to particular spots on the hill. The Grimmia edinensis of Fergusson 

 is made up of specimens of G. orbicularis and G. subsquarrosa. What is 

 usually called G. jnilvinata, var. /3. africana, is the typical form of G. orbicu- 

 laris of Schimpei"'s Synopsis, the common G. orbicularis of Arthur's Seat 

 bemg, according to Mr. Wilson, the var. elongata. " Notes on some British 

 Mosses." By Mr. William Wilson. Communicated by Mr. Sadler. Mr. 

 Wilson referred to the British species of Andrcea, which he has revised for a 

 second edition of the ' Bryologia Britannica' now in preparation, and to Didy- 

 modon Jenneri, a Moss recently described and figured in the Society's Trans- 

 actions, and which he believed to be in no way specifically different from Cg' 

 nodonfium polycarpon. " On the Ferns found in the Valley of the Derwent." 

 By Mr. T. W. Mawson. Mr. Mawson enumerated twenty-eight species and 

 varieties, e.g. Asplenium germanicum, A. septentrionale, Hymenophyllum Wil- 

 soni, Osmunda regalis, Allosorus crispus, Ophioglossum vulgatum, etc. Dr. 

 Christison presented bulbs which had been produced in place of fruit on a 

 large plant of Fourcroya gigantea at Agra. Mr. Sadler recorded new stations 

 for CameUina saliva, Erysimum cheiranthoides, and Calicium chrysoeephalum, 

 near Edinburgh. Professor Balfour exliibited growing plants of Saxifraga 

 cernua, which had been cultivated in the Royal Botanic Garden for many years 

 without clianging in their oliaracter. Mr. W. Wilson sent growing plants of 

 Wolffia arrhiza. Mr. Charles Howie presented flowering specimens of the 

 Wild Hyacinth, having tlie flowering axis very much shortened, and the sta- 

 mens petaloid.
