Read " Notes on a variety of Rosa sarmentacea (Woods) (found 

 near Bridgewater by Mr. Clarke)," by Mr. Edwin Lees, F.L.S. &c.

 was considerable difference in the more or less deeply cut serratures 

 of the foliage, he always found the calyx to be fringed with stalked 

 glands as well as the flower-stalks ; the tube is generally but spa- 

 ringly so,_ or even naked. It is abundantly covered with glands in 

 this specimen, which is, therefore, a more than usually glandulose 

 variety of It. sarmentacea. In some MS. observations on this species 

 made in 1836, Mr. Lees observed : —

 which, united to a purplish bloom on their segments as well as on 

 the tube, gives this rose a peculiar and very elegant appearance/* 

 The petioles are always more or less glandular, without prickles, 



differing in this respect materially from R. canina, as well as in the 



particulars mentioned above. 



Mr. Lees had often observed, that the young foliage of this species
