has a faint but very perceptible cowslip-like scent, by which he could 

 always tell it when not in flower, but had never observed this in the 

 leaves of R. canina. 



Mr. Lees contended for R. scahriuscula being a good species, 

 though it must be observed, that the calyx-tube varies in being more 

 or less covered with stalked glands, and therefore Smith is wrong in 

 the * Enghsh Flora' in saying with regard to it, " quite smooth and 

 naked." 



The character of the plant as diflfering from R. canina is in the glan- 

 dulosity of the pinnate calyx and peduncle, and in the petioles being 

 slightly glandular, without prickles, or with very weak ones. 



This variety was not, as far as Mr. Lees's observations had gone, 

 abundantly distributed, being somewhat local and plentiful only in 

 particular places.

 Bristol," by Mr. G. H. K. Thwaites. 



The author enumerated 133 species as indigenous to that locality, 

 several of which appear to be new to the British Flora. Amongst 

 those most interesting to the British muscologist may be noticed the 

 following : —

The President drew the attention of the Society to an abnormal 

 form of Ophrys ajnfera which had been sent to him by a lady from 

 Dorking. The two lower flowers of the sjiike had two distinct united 

 columns, the upper normal one being rather the larger and overlap- 

 ping the other ; the upper flowers had three columns united into a 

 singulai- triangular mass ; the upper petals of each of the flowers were 

 rather reduced. The lip of the two lower flowers was small, and 

 retained in part the usual character of the flower, but the lip of the 

 top flower was lilac, and exactly resembled the sepals in form and 

 colour. The three sepals of the middle flower were united together 

 nearly to the lip, as was the case with two of the sepals of the ter- 

 minal flowers. The ovaries of all the flowers were of the normal 

 structure. The President stated that the Rev. Gerard E. Smith had
