than in lamprocarpus, and like the bracts, as pale in colour as 

 those of /. obtusiflorus. My American specimens were gathered 

 by Mr. Sartwell on the shores of Lake Ontario, and that gen- 

 tleman has also met with the ordinary form of lamprocarpus in 

 the States, as duly noted by Professor Gray." 



PLANTS OF LLANGOLLEN. 



Flora of Castell Dinas Bran, with a Notice of a few Plants in the 

 Vale of Llangollen. 



(In a Letter to the Editor.) 



Sir, — Being detained a few hours in the fashionable town of 

 Llangollen, I took a walk up the steep hill on which there are 

 the remains of the ancient fortress of Dinas Bran. The following 

 is a list of the plants observed growing on its weather-beaten 

 walls, or on the adjoining vallum or fosse-bank (June 21, 1859). 



Filices. — Polypodium vulgare, Asplenium Trichomanes, A. 

 Ruta-muraria : on the walls. 



Veronica officinalis and V. Chamsedrys : on the walls. 



Hieracium vulgatum : the variety with the spotted leaves. 



Linum catharticum. 



Campanula rotundifolia : one floAver expanded (June 21, 1859) . 



Myosotis collina. 



Teesdalia nudicaulis : very nearly decayed. 



Draba verna, var. turgida. 



Arabis hirsuta : minute and dwarf examples, none of tliem 

 above six inches high. 



Sedum anglicum : the leaves are ovate, very fleshy, with 

 scarcely any spur. 



Oxalis Acetosella : on the wall. 



Scabiosa Columbaria. 



Saxifraga tridactylites. 



Cerastium viscosum. 



After crossing the bridge of Llangollen, and before reaching 

 the canal-bridge, there is an old brick or stone wall on the left, 

 and on its top there is a stunted form of Pyrethrum Parthenium, 

 without the ray-florets. 



Geranium columbinum grows sparingly on the edge of the path 

 leading to the first pair of cottages on the way to Dinas Bran.
