Descends to the coast level, in the Peninsula.

Native. Septal. In the first five provinces, occtn-s co- 

 piously in many places, on chalk or other calcareous ground. 

 In South Wales, very local ; being recorded only fi-om Gla- 

 morganshire. In North Wales, solely on the authority of 

 Mr. Rowland, who includes it in his list of plants observed 

 about Wrexham. In Trent, occurs at Nottingham Castle, 

 and is reported to gi'ow elsewhere in the same county. In 

 Humber, may possibly be indigenous in the hedges near 

 Whitby, where it was observed by the Rev. Andrew Bloxam. 

 In Tyne, said to be naturalized on the ballast lulls. In 

 Scotland, has been reported from the neighbom-hood of 

 Edinbiu-gh, and of Callander ; but doubtless planted there. 

 The type of distribution may be deemed intermediate be- 

 tween the English and Germanic ; the Clematis being too 

 frequent in the Peninsula and Severn provinces, to allow of 

 its type being held strictly Germanic, although so very rare 

 in Wales.
