58 Plants in the Neighbourhood 



I send you a list of the plants which I found growing on the 

 hills, and in the neighbourhood of that place. Many that 

 are rare in the midland counties of England I found to be 

 very common in North Wales: Geranium sanguineum and 

 Cotyledon Umbilicus ; the former on the hills, and the latter 

 on every wall and rock in the neighbourhood. . /0 da 



Lichens.— \ found but few lichens that I had not pre- 

 viously met with in Worcestershire, on Malvern Hills. Par- 

 melia conspersa of Acharius was the only new species. On 

 the same-stone I also found (and in fruit) Parmelia olivacea. 

 The rocks were chiefly covered with Parmelia omphalodes, 

 Lecklea confluens, L. geographica, Lecanora parella, and 

 Farina pertusa ; Sphaerophoron corallbides and S. fragile
