PLANTS OF NORTH ELBA 89 



vicinity of Albany. The plant grows on the summit of Mt Mclntyre 

 but I have not seen it in fruit there. The climatic conditions are 

 probably too severe for it. 



Rubus Americanus {Pers) Britton 



R. tri/lorus Richards. 



Dwarf raspberry 



Swamps and wet places. Common. June. The fruit is not plentiful 

 but it has an agreeable flavor. It separates from the receptacle with 

 some difficulty and has by some been considered a blackberry on this 

 account, though in other respects its affinities are with the raspberries. 



R. Americanus roseiflorus Fk, 



This variety differs from the typical form in having pink or rose 

 colored flowers. I have found it in woods only. Adirondack lodge and 

 Wood's sap works. 



Rubus Canadensis L. 



Low BLACKBERRY. RUNNING BLACKBERRY. DeWBERRY 



Pastures and roadsides. Wood farm. June. 



Rubus setosus Bigel. 

 Bristly blackberry 



Roadsides, pastures and clearings in soil either wet or dry. Ray- 

 brook and in the eastern part of the town. July, In this species the 

 stem is generally densely armed with short stiff bristles. Its fruit is 

 small and similar to that of the preceding species, but inferior to that 

 of the three following. The species is apparently limited in our state to 

 the Adirondack region, where it seems to take the place of the running 

 blackberry, 7?. hispidiis L. 



Rubus Millspaughii Britton 



Millspaugh's blackberry 



Roadsides, thickets and thin woods. Common. July. The species 

 is distinguished by being almost or entirely glabrous and in having the 

 stem unarmed or bearing only a few weak prickles. 



Rubus Allegheniensis Porter 

 Mountain blackberry 

 Hillsides and thickets. Best separated from the following species by 

 the fruit which is oblong or thimble shape, less pulpy, with smaller seeds 

 and drupelets and a peculiar rich and agreeable flavor.
