keeps quite distinct from typical R. Borreri, which I saw growing 
near it in two or three spots. R. Briggsianus and h. ramosus are 
equally well ae —_ often on this high ground with rather 
weakly developed panicles. R. argentatus and R. cngustlis are 
new for Sou evon. RR. mucronatus (uncommon in South-west 
England) is locally abundant lower down than the rest, ‘adie: Hay

Every botanist in search of plants often expects to find what 
he does not find, and finds what he does not expect. Thi uld 
not so frequently be the case if he took into consideration the 
ch i he i n 
flora he will see plants called ‘‘ common,” which in his neighbour- 
hood are never seen, and “rare,” which occur abundantly. If the 
method proposed by Mr. Woodruffe-Peacock in his paper, How to 
make Notes for a Rock-Soil she were carried out for every count 
as he has carried it out for Lincolnshire, many a fruitless eaich 
would be abandoned, and supposed rarity — be found 
to be only what might have been expected. Wi to
