Obs. — This, the handsomest of our native Radida, was 

 deservedly named by Jack in honour of its original discoverer. 

 Dr. Carrington, who collected it in the South of Ireland in 1861, 

 and thought it was a distinct species, although he had not seen 

 either the male plant or perfect perianths, but deferring to the 

 opinion of some of his friends, he published it as var. major of 

 Uadida aquilegia, Taylor ; since then, the male plant along with 

 more perfect female plants have been met with, which clearly show 

 its specific difference from the latter. 



It is distinguished from R. aquilef/ia by its larger size, rather 

 paler brown colour, which is golden brown by transmitted light, 

 leaves with less convex antical lobes ; postical lobe relatively larger, 

 plane, appressed to the antical lobe, not turgid at the base, free 

 angle more acute, texture thinner and more translucent ; androecia 

 on short catkins proceeding from the main stem. From any of 

 the other British Radulm it is abundantly distinct.
