“Found by Mr. G. Don in 1795 or 1796, by the side of a 
rivulet in marshy ground among the mountains of ee 
but very rarely. It appears to us to be a nondescript, but w 
received from Mr. Dickson, some few years before the ziove 
date, a specimen not so far advanced towards maturity, of 
what seems to us the same species.” Smith h, Eng. Bot., t. 2174

There is a specimen in Herb. Palmer and in Don’s own 
herbarium, the latter localised—“the only place we are 
acquainted with where this rush ( Juncus gracilis) grows in 
Britain is on the Clova mountains, rare.’ 
Juncus tenuis, which is probably an adventitious plant in 
Britain, and of North American origin, has been found during
