NOTES ON A FEW MORE BUCKINGHAMSHIRE RARITIES. 



July, 1864.

 On another occasion I went to Taplow, about ten miles from Wycombe> 

 to meet a friend from London. While waiting here, I looked about me, 

 and observed Corydalis lutea in considerable abundance on a wall ; a locality 

 which is open to suspicion. Erysimum cheirantlioldes appeared here and 

 there by the roadsides, but in no great quantity ; and a small meadow 

 was completely filled with Armoracia rusticana, a plant which, if not an 

 original native, must have held its ground for very many years. The 

 railway embankment produced Erigeron acris in some quantity, with the 

 small form of Melilotus officinalis known to some botanists as M. arvensiSf 

 but which does not appear to be the species usually intended by that name : 

 and in some old, and apparently disused pits, Trifoliiim arvense was abun- 

 dant, with Erigeron acris and EcJmim vulgare, the last very bright and 

 beautiful. Linaria spuria occurred in the cornfields, and in a ditch near 

 the Thames I noticed several plants of Sparganium natans ; this terminated 

 my observations in this neighbourhood. 



A very profitable day was the one which I spent at Medmenham. At 

 Danesfield, on the left-hand bank going from Marlow, and at some dis- 

 tance from the house, was Campanula Rapunculus, growing in some plenty, 

 though extending over but a small space of ground. With it was Epilohium 

 angiistifoliuni, and this occurred at intervals for a considerable distance. 

 Further on, at the top of the bank on the right of the road just beyond the 

 bridge which crosses the latter, was a large patch of Hypericum calycinuni^ 

 and near this two rare Sedums, S. dasyphyllum and S. sexangulare, to- 

 gether with another not mentioned in our Floras, but which ai^peared 

 something like the garden S. oppositi/olium, from which it differed in hav- 

 ing red flowers. The occurrence of four such suspicious characters in 

 close proximity forces the opinion that they must here have been intro- 

 duced, though there was no a]3parent trace of such introduction. The 

 three Sedums were in but small quantity, each having about six flowering
