20 Report of the State BotajsIst. 



Defiance, near Ticonderoga. They differ from Rosa Sayi in tlie 

 shape of the fruit, which is distinctly longer than broad. 



Rubus Millspaughii Britton. 



Avalanche Pass, Essex county. iV. L. Britton. Morehouseville, 

 Hamilton county. July. 



The glabrous character of this species separates it from small 

 forms of Ruhus villosus var. frondosus. The specimen contrib- 

 uted by Professor Britton is wholly without spines, those col- 

 lected by myself have a few weak spines. 



Rubus setosus Bigel. 



Common in the southern and western part of the Adirondack 

 region, Morehouseville and Lake Pleasant, Hamilton county, 

 Old Forge or " Brown Tract," Herkimer county, and Garoga, 

 Fulton county. July and August. 



This plant was previously reported by me as RuTms hispidus 

 var. suherectus, but later observations led me to the belief that it 

 is a distinct species. Professor Britton agrees with me in this 

 belief, and thinks it belongs to the speciss under which I have 

 now placed it, and with the originally published description of 

 which it agrees very well, except that its ripe fruit is black 

 instead of red, as inBigelow's plant. Doctor Torrey, in IS". Y. State 

 Flora, regarded Bigelow's plant as a variety of Ruhus Mspidus and 

 abbreviated the description too much to make it satisfactory. 

 The specimen which he placed in the Herbarium as a representa- 

 tive of this plant is clearly a mere form of R. hisjndus. 



R. setosus, as here understood, is quite plentiful in the localities 

 mentioned and evidently delights in the soil of mixed sand and 

 gravel which is common in that region. I observed the past 

 season that it had taken possession of the old neglected garden of 

 Arnold house, Fulton Chain, and was apparently fast overrun- 

 ning the whole area. It thrives better on dry upland than in wet 

 swampy places, though it occasionally appears in such localities. 

 The old abandoned fields and pastures of the region mentioned are 

 most congenial to it. Unthrifty specimens of it were seen on the 

 summit of Bald mountain near Third lake. In no case have I 

 found it associated with R. Mspidus, which is strangely absent or 

 scarce in this whole region. The fruit is ripe in August. It is
