ADDITIONS, REMARKS AND OBSERVATIONS. 27 



so that leaf-bearing specimens are yet wanting. I do not find this 

 plant recorded in any of the local catalogues of plants of various 

 parts of the State, and Dr. Torrey admitted it in the New York 

 Flora with the following explanatory remark : "I am not quite cer- 

 tain that I have received specimens of this plant from within the 

 limits of the State ; but it doubtless grows in some of the northern 

 counties. " The result has proved the accuracy of his supposition, 

 but the plant is evidently rare in our State. 



Potamogeton paliciflorus Pursh. 



A peculiar form of this species occurs in Glass lake, Rensselaer 

 county. The stems are 1 to 2 feet long, the spikes numerous 

 and axillary and the foliage of a dull-brownish or reddish-brown 

 color, quite unlike the ordinary bright-green hue of the species. 



Pogonia affinis Aust. 



In a swamp near Tappantown, Rockland county. June. E. F. 

 Smith. 



Jimcus Canadensis var. coarctatus Engelm. 



This plant sometimes has the flower heads wholly or in part

 duced by the attacks of insects. 



Clitopilns Noveboracensis Pk. 



Sometimes the pilens is dark-brown, much darker than in the 

 typical form. There is also a variety tomentosipes, in which the stem 

 is clothed with a whitish or grayish hairy tomentum. The plants 

 are also sometimes csespitose. Sandlake. July. 



Entoloma strictior var. isabellinus Pk. 



Pileus, when moist, of a watery isabelline hue and striatulate on 

 the margin, when dry, whitish or pale straw color. 

 Sphagnous marshes. Sandlake. August. 



Clavaria ainethystina Bull. 



Woods. Sandlake. July. 



Sometimes the color inclines to a grayish-violaceous hue. Both 



the small sparsely branched and the abundantly branched forms 



occur. 



Dacrymyces conglobatns Pk. 



Plate 1, figs. 1-4. 



In the Thirty-second Report, this was provisionally referred to the 

 genus Dacrymyces. It is apparently Peziza rubella Pers., and Om-
