I am not certain of Trachelium minus, Park, 
which is • faid to be common : but there are cer- 
tainly in this ifland, and even in this neighbour- 
hood, many fpecies of this genus, that I cannot 
find to, have been defcribed or mentioned.

“ iimbrofis et rofcidis, inque aggeribus umbrofis et 
“ muris antiquis magnus ejus per toiam Angliam 
“ eft proventus.” According to my obfervation,. 
it is rare in moft of the Englifti counties ; but 
common hereabout, and much more fo in fome 
• parts of Wales. The walls of the bridge and the 
walls and roofs of fome houfes at Bethgelert in 
Carnarvonftiire, are almoft covered with it.

heathy hills j but, as far as I have obferved, more

Snowdon, with an extremely fmall leaf, having 
frequently a large red excrefcence, the nidus of an 
infeift.
