Hab. Bogs and marshes, Dublin, D. Orr ; Lough Bray, Wicklow ;

It was for the discovery of this moss and Schistidium maritimum, 
and for " a vegetable substance," found in the bed of a rivu- 
let in Queen's County, that Dr. Eobert Scott received a pre- 
mium of £17 \s. Sd. from the Dublin Society, in 1803, at 
the same time that £o 135. 9d.^ was awarded to Mr. Templeton 
for Hosa Hihernica. Dublin Society Proceedings, xxxix., p. 82
