No. 104.] 55 



■was found producing berries of unusual size. Many of them were 

 found by actual measurement to be h\\\y a half inch in diameter. 

 They were sweet and agreeable to the taste and grew in close clusters 

 of three to six berries. This form would be a most desirable one to 

 introduce into cultivation if it can be made to thrive as well in other 

 localities as it does in its native one. The same variety, bearing 

 more abundant though smaller fruit, was found growing in a marsh 

 in the same town. This would indicate its adaptability to a variety of 

 soils. 



Clethra alnifolia, L. 

 The sweet pepper bush or white alder is abundant about Spruce 

 pond near Southfield; also on Skunnemunk mountain. In the former 

 locality, a plant of Leucothoe racemosa was also observed. 



Menyanthes trifoliata, L. 

 Spruce pond near Southlield. The flowers are dimorphous. On 

 some plants the stamens are longer than the pistils, on others shorter. 



Apocynum androssemifolium, L. 



There are two forms of our common dogbane, in one of which the 

 flowers are nearly twice as large as in the other. 



Celtis occidentalis, L. 

 "Near Saugerties. The hackberry is not rare in the lower part of the 

 Hudson river valley, but northward and westward it is seldom found. 

 I am informed that a tree of this species growing in the Mohawk 

 valley, near Sprakers, is such a novelty that it has received, from the 

 inhabitants the name of "the unknown tree." 



Nyssa multiflora, Wang. 

 Abundant on Skunnemunk mountain where it forms a tall tree and 

 has a trunk twelve inches or more in diameter at the base. 



Betula nigra, L. 



The red birch was admitted into the New York Flora by Dr. Torrey, 

 on the authority of Dr. J. Carey, who gave Saugerties as its locality. 

 No specimens were placed in the Herbarium. Desiring New York 

 specimens, I visited Saugerties and found several trees growing along 

 the banks of the iEsopus river south of Saugerties. The species is 

 easily known by its rough bark, curved branches and long drooping 

 branchlets. The bark of young trees is smooth and whitish or red- 

 dish-wliite and such trees might easily be mistaken for the paper birch 

 or poplar leaved white birch. 



Alnus viridis, D. C. 



Plentiful on Cobble hill, also along the road between Elizabethtown 

 and Keene. 



Arissema triphyllum, Torr. 



The apex of the spadix of tlie Indian turnip is generally obtuse. A 

 specimen was found near Albany, in which the spadix was abruptly
