On the Species of the Genus Primula in Essex. 177 tyn's 'Methodus' (1727), 71. Woods, on clay. (1) Wood Ditton, Park Wood, wood near Bartlow, Yenhall Wood, West Wratting, Balsham, Borley, and Westley Woods; (3) Eversden, Kingston, and Hardwicke Woods; Hayley Wood ; between Longstow and Bourne ; (4) Knapwell Wood, Madgingley Wood (Ray)." The information given in Webb & Colman's 'Flora of Hertfordshire' (1849, p. 234) is very unsatisfactory. It is as follows:—"What the plant of our correspondents may be we know not, not having received specimens; but we fear our own is nothing but an umbellated variety of P. vulgaris. Woods, rare. (1) Woods S. of Brickendonbury; copse, Bramfield Brook Bottom, Stanstead Thrift Wood; (6) Box Wood, Hertford Heath, Glebe Wood, Essendon; (9) wood near Little Heath, Haresfoot Woods; (10) St. Albans, Laverstock Green; (11) Hitchin." Appendix III., 1859, gives also "Coles, and between West Mill and Stonebury." P. elatior does not occur in Middlesex or in Kent. All the localities in Suffolk and Cambridgeshire appear to adjoin our Essex stations. Until more satisfactory informa- tion is obtained, I prefer to discredit all the Hertfordshire localities, except perhaps Stanstead, which adjoins an Essex locality. Therefore, as the Essex localities all adjoin one another, I believe I am correct in saying that, so far as we know at present, P. elatior is confined to a single district in East Anglia, without any outlying stations. Both Mr. Baker and Mr. Newbould have most kindly assisted me with information as to the geographical distri- bution of P. elatior outside England. It appears to grow in Denmark, S. Sweden, Belgium, Holland, Germany, Switzer- land, Central Russia, Caucasus, Siberia (to Altai and River Yenesei), Austria, Hungary, Transylvania, Croatia, Bosnia, Herzegovina, Servia, Dalmatia, Crimea, N. Italy, France, and N. Spain. Mr. Baker writes—" The Oxlip and the Primrose, broadly speaking, seem to have almost the same wide range of distribution in Europe and Asia, and the altitudinal range of both is very wide. Why do they, then, and especially the Oxlip, behave in such an eccentric manner
