THE^FLORA OF MOHAWK HILL, N. Y., NORTH OF 

 THE WATERSHED 



By T. a. Bendrat 



On the basis of several seasons' work the writer endeavors to 

 show in the present paper the general distribution of plant- 

 forms north of the watershed that separates the drainage system 

 of the Black River from that of the famous Mohawk, and which 

 have been established at an elevation of about 1,700 feet, between 

 latitude 43° 30' and 43° 35'. 



The area investigated comprises the drainage basin of the 

 Sugar River, a western tributary of Black River, and more 

 especially that of Amster Brook, which is a southern tributary 

 of Sugar River. The area is limited on the south by the water- 

 shed itself and on the north by the valley of the Sugar River into 

 which it gradually merges. 



A partial list of the more common seed-bearing plants of the re- 

 gion is followed by a more or less condensed discussion of the 

 various formations, their mode of occurrence and their relation 

 to one another, and also by a subjoined formation-map which 

 has been constructed on the basis of a topographic map and 

 which may serve to emphasize, at least for a portion of the area 

 under discussion, the facts brought out in this paper. The topo- 

 graphic map is also the work of the writer. 



List of the More Common Seed-bearing Plants, with 

 Notes on their Habitats and Flowering and 

 Fruiting Periods* 

 GYMNOSPERMAE 

 Abies halsamea (L.) Mill. Found both in lowlands and uplands, 

 in the valley and gulf formation as well as in the plateau- 

 forest formation. Flowering early in June. 



* Wherever the date, as July-August, is given it applies only to the period of 

 flowering. The writer has also indicated the period of fruiting, for many species, 

 as will be noted in the text.
