peculiar structure of the calyx ; but the leaflets are not 

 coriaceous, the pedicles longer, the calyces twice as long, 

 thus reaching much higher up to the corolla, and the teeth 

 of the column are neither rounded nor retuse-truncate ; 

 the fruits are likely also different.

Rejjort on Temperatur'es and Open- Air Vegetation at the 

 Royal Botanic Garden, Edinburgh, from November 1881 

 till Jidy 1882. Compiled from Notes read at Meet- 

 ings of the Society. By the late John Sadler, 

 F.R.Ph.S., Curator. 



The forest trees and shrubs flowered remarkably well 

 during the early summer of 1881, and most of them pro- 

 duced fruit. The garden suffered very little from the 

 great storm of October 1881. 



In November 1881 the thermometer was seven times at 

 or below 32^. On two occasions it stood at 25°. The dates 

 of these low temperatures were the 1st, 2nd, 4th, 8th, 18th, 

 and 26th. 



Upwards of thirty species and varieties of plants were in 

 full flower in the rock garden ; Christmas roses blooming 

 for two or three weeks. 



In December the thermometer was at or below the 

 freezing-point on sixteen occasions. The greatest frost 

 was on the 22nd and 23rd, when 26° and 23° were respec- 

 tively registered. These were relatively high readings, 

 when compared with the same month, as well as that of 

 November 1880. 



In January 1882 the thermometer fell below the freezing- 

 point on six occasions, as compared with twenty-seven 

 occasions in January 1881. On the 4th and on the 29th, 

 28° and 26° were respectively registered. 



In the rock garden fifty-two species and varieties of 

 plants had flowered, including fourteen species of Hellebore, 

 as well as mignonette, besides crocuses, pansies, and 

 roses.
