or single sheets, but enough to enable ub tO' preserve 150 speci- 

 mens, if necessary. 



The writer's collections and notes 00 the Stoutb Jersey plants 

 accumulated rapidly, and the arrangement of the data was for- 

 tunately well under way when Professor Morse offered to pub- 

 lish them', as part of his annual Museum Report. The basis of 

 the present work is the field work of the author and his friends, 

 the South Jersey material in the herbaria listed below and 

 the published records contained in the several botanical works 

 dealing with the region. Wherever possible, an actual her- 

 barium specimen is cited for every locality mentioned under each 

 species, so that questions of correct identification can readily be 

 settled in the future by consulting this material. This plan has 

 been followed even in the cases of common species, since general 

 statements leave much to be desired that is sometimes supplied by 

 actual records. The number of records is, however, no index to 

 the relative abundance of a species, this matter being covered by 

 the preliminary statement based upon much additional field data. 

 The statements regarding the occurrence and abundance of the 

 wide-ranging species in northern New Jersey, are taken direct 

 from Britton's Catalogue. Published records not backed by 

 actual specimens cannot well be ignored, and they have, in 

 nearly all cases, been included in the text. When they . have 

 been proven to be wrong, or seem exceedingly doubtful, they 

 are referred to in foot-notes, and where there seems nO' reason 

 to question their accuracy they are included with the other rec- 

 ords, but distinctly marked as to their source. In rare cases of 

 exceedingly difficult groups where such records are of no par- 

 ticular additional value to the definite knowledge already pos- 

 sessed, and where the exact application o'f the names used is in 

 doubt, they have been^ omitted.
