Mr. T. R. Archer Briggs reports that the remarkable Viola, 
mentioned in the last year's report as having been found by him 
near Plympton S. Maurice, has since been identified by a Conti- 
nental botanist, M. Jordan, with his own permixta, gathered in the 
neighbourhood of Lyons. 
During the past season, Mr. Briggs has added to the Floras of 
both Devon and Cornwall, Lepigonum rupicola, Sagina ciliata, and 
Galium tricorne ; to that of Devon alone, Alliion oleraceam ; to 
that of Cornwall, Rosa tomentosa, Potentilla argentea, and Scirpus 
sylvaticus. The naturalized Lepidium Draba he has detected near 
Horrabridge : the equally alien Mimnlus hiteus in both the Plyra 
and Erme. The latter was observed last summer by one of your 
Secretaries in great abundance in Martindale and other valleys in 
the neighbourhood of Ullswater, and elsewhere in the Lake 
district.
