plentifully near Newbury Wash Common. At Enborne a small 

 strongly marked variety occurs with very fine leaf cutting. 

 5. Loddon. A plant occtarred at Bearwood which the Kev. 

 W. M. Eogers says has some affinity with rudis, in spite of the 

 very different armature. Dr. Focke marks it B. Koehleri with 

 some doubt. 

 Plants named R. Koehleri for me by Dr. Focke have been seen at 

 Bearwood and Greenham, and the Rev. W. M. Rogers has seen it at Cat- 

 more. The aggregate species occurs at Didcot and elsewhere, and is 

 recorded for all the bordering counties.
