460 Air. Babington on several new and imperfeclly understood 



Stem 5 or 6 feet high, round, striated, branched, smooth, not scabrous ; 

 leaves alternate, stalked, triangularly cordate ; racemes axillary and ter- 

 minal, lax, elongated ; floivers with long stalks, when in fruit reflexed, 

 the fruit triquetrous, oblong, quite smooth and shining, covered by the 

 very broadly winged persistent enlarged perianth, which is shorter than 

 its jointed footstalk. 



Found September 20, 1834, in a wood at Wimbledon, by Mr. J. A. Hanhey, 

 who kindly presented me with a specimen. Some doubts having been 

 expressed as to its identity with P. dumetorum, Linn., I was induced, on 

 obtaining additional specimens from my friend Mr. C. E. Broome, gathered 

 at Wimbledon by Mr. W. W. Saunders, to submit it to a rigid examina- 

 tion, and have determined that the synonyms given above belong truly 

 to the Wimbledon plant. O . September.
