—lIt is interesting to record here, what has not been pre- 
sioudy uplshed that Professor Barker first discovered Grimmia 
arenaria Hampe as a British plant near Dolgelly, Merionethshire,

it near Capel Garmon, Denbighshir 
“JUNCUS TENAX.”

Ix. Brivren having drawn my attention to a certain confusion 
of species under the name stage tenax Soland., we went into the 
matter with some care, and with the aid of the literature, including 
the invaluable manuscripts of sae and Solander, arrived at con 
clusions which may be worth recording.

The identity of this New Zealand plats as hitherto been 
doubtful. EH. H. F. Meyer, in his Synopsis Juncorum (p. 
(1822), puts it among the species dubie. Wikstrom, in K. Vetensk.
