than in R. involuta, but I fail to find any other constant differ- 
ence. The sepals are very often reflexed, but forms of R. tomentosa 
frequently have them so. The biserration of the leaflets is not 
always so compound as in Baker’s an oods’s specimens, 
though perhaps usually more so than in R. involuta. They are 
occasionally glandular-scabrous on midribs, but very rarely so on 
secondary veins. Mr. Baker considers this much the most 
common representative of the group, reaching its maximum 
frequency in the North of England.
