KE-ISSUE OF THE FLORA OF nERTFORDSHIKE. 31 



friend Master Nicholas Belson founde in a gravellie lane in the 

 way leading to Oxey Park, neare unto "Watford, fifteene miles 

 from London." I have no other notice of the existence of Scolo- 

 pendriuin in the district, where, however, it will almost certainly be 

 met with. To the observations of the same old herbalist we owe, 

 I believe, the earliest record of the occurrence of Malva moschnta, 

 Alchemilla vulgaris, Carnpamila Trachelium, Lamium Galeoldolon, 

 Butomns umhellatus, and Convallaria maialis in Hertfordshire ; all of 

 which were remarked by Gerarde in the neighboui-hood of Bushey 

 and "VYatford. 



Aspidium amleatimi. — Near Bacher Heath. This is called lohatum 

 in the ' Flora Hertfordiensis,' but the plant of the immediately 

 adjoining districts of Middlesex appears to be aculeatum, and the 

 two forms were confused by the authors of the Flora. A. angulare, 

 for which I have no stations in the Watford district, may, perhaps, 

 also be occasionally included with it. 



JSfephrodium sjnnulosum. — Oxhey Woods ; Aldenham "Wood. 



JSf. dilatatum. — Berry Wood, Aldenham; Newland's Wood. 

 These two are often confounded together, and the Aldenham 

 plant at least requires further examination, as it is possible that 

 the two names may represent one and the same thing. iV. dilatatum 

 was also recorded by Blackstone from a bog near Moor Hall, in 

 company with Saxifraga granulata and Bipsacus pilosus. This 

 may have been at Harefield, but Moor Park was occasionally 

 called by that name, and so Edward Forster seems to have under- 

 stood it. 



N. oreopteris. — With the last in Aldenham Wood. Eecorded 

 also from Bushey Heath, but it has been ascertained that the 

 station is in Middlesex. 



Equisetum maximum. — Rickmansworth, by the road to Denham. 

 The only station, and not known to occur anywhere in the 

 neighbourhood. 



I have put together, as an Appendix, a list of those plants which 

 have been observed in the immediately adjoining portion of Middlesex, 

 but which have not yet been recorded for the Watford district. 

 Some of these, however, rest upon the testimony of the older 

 authors only, and have not been noticed for many years. They 

 are principally from the neighbourhood of Harefield, Pinner and 

 Harrow Weald, and Stanmore Heath, 



Rammculus parviflorus. Sagina ciliata. 



Papaver Argemone. Eadiola Millegrana. 



P. hybridum. Oxalis corniculata. 



Brassica Rapa (var. sylvestris). Impatiens fulva. 



Sisymbrium Sophia. Meclicago maculata. 



Cardamine hirsuta. M. deuticulata. 



Nasturtium sylvestre. Melilotus arvensis. 



Lepidium campestre. Trifolium subterraneum. 



Viola canina (vera). T. fragiferum. 



Moencliia erecta. T. hybridum.
