plant for several months, and a fire in fall or early winter would 

 be disastrous to them. (It is not claimed that fire is unknown 

 in this region, however. Evidences of it may be seen in many 

 places in the woods, but it probably does not occur often enough 

 in any one spot to have any lasting effect on the vegetation.) 



Comparisons with other regions. — The following species are 

 evidently more abundant here than in the unglaciated portion of 

 Queens County on the south and the glaciated portion of Nassau 

 on the east, both of which have poorer soils: — Trees: Lirio- 

 dendron, Liguidamhar , Ulmus, Qiiercus hicolor. Siviall trees: 

 Viburnum prunifolium, Carpinus. Vines: Rhus radicans , Celas- 

 trus. Shrubs: Ruhus nigrohaccus? , Decodon, Vihurnum denta- 

 tum, Samhucus, Benzoin, Ruhus occidentalis . Herbs: Aster di- 

 varicatus, Geranium, Washingtonia longistylis, Arisaema, Falcata, 

 Carex rosea, Washingtonia Claytoni, Tovara, Allium, Circaea, 

 Dryopteris Noveboracensis, Juncoides campestre. 



An investigation of what species are less abundant here than 

 elsewhere brings out some interesting facts. The plants listed 

 below are fairly common in some places within lOO miles of here, 

 either on Long Island or on the mainland, or both, but com- 

 paratively rare or wanting in the area under consideration. 

 Where the name of a genus (or family) stands alone it means that 

 several or all of the northeastern species (in some cases there is 

 only one in the northeastern flora) are found not far away, but 

 none are common here. Where the generic name is followed 

 by 'spp.' it means that some of the species are common elsewhere 

 and rare here, but there may be one or more common here too. 

 Where such genera have been subdivided lately {e. g., Andropogon, 

 Clematis, Saxifraga, Prunus, Linum, Cornus, Gentiana) the 

 names are here used in the older and broader sense, unless some 

 particular segregate or species is designated. If space permitted 

 one might go through a manual, or Taylor's recent Flora of 

 the vicinity of New York, and pick out many additional species 

 which from the published statements about their ranges might 

 be expected to be common here but are not. Of course native 

 plants only are considered. In this list the names of evergreens 

 only are in italics, and of families in small capitals.
