Structure of flowers, they would fade before such ilhistrations as 

 these. The great prevalence of this character in clover this season 

 was certainly remarkable. I saw fields in which perhaps one-fourth 

 the crop had heads like these ; though rather in patches than spread 

 regularly all over the ground. There was also a perceptible yellowish 

 tint in the patches with the most of these abnormal characters. I 

 could not find any trace of fungus development in these specimens, 

 yet from analogy — the pale tint following fungus attacks in other 

 plants — I think it must have been from such organisms below the 

 reach of ordinary microscopic power, interfering with nutrition, that 

 these curious morphological results were developed. My observa- 

 tions of plants generally lead me to believe that w^e must look to the 

 physiological functions of plants, and the laws w^hich affect them, 

 before we can comprehend the morphological change which they 

 undergo.

While making occasional botanical trips for the past few years to 

 Nockamixon "Township, Bucks County, I detected the following 

 plants, which Dr, J. S. Moyer, of Richland Centre, who has pub- 

 lished a catalogue of plants of this county, informed me are new to 

 the flora : ^ 



Liparis Loeselii, Richard, found growing along a 'wet mossy bank 

 near Narrow^sville, July, 1874. 



Struthiopteris Gerinanica, Willd., found in profusion and great 

 luxuriance along the bank of the Delaware River near Narrow^sville, 

 May 22, 1879. 



From the mountains near Bauer's Rock, Lehigh County, Robert 

 Rau in 1868 collected the rather scarce and local plant Pogonia pen- 

 dula, Lindl., w'hich is the only source of specimens I have for this 

 region* 



• Reseda lutea^ L., and Glaudumcor7iiculatum^ Curtis, I found grow- 

 ing in tolerable abundance upon piles of African iron ore near the 

 works of the Bethlehem Iron Co. Mr. I. C. Martindale, to whom I 

 am indebted for the identification of the species, states that both 

 plants are natives of Europe ; whether also of Northern Africa he 

 does not state, although it seems not improbable. 



Airiplex paiula, L., var. hastafa, several years ago made its appear- 

 ance along the railroads near Bethlehem. 



Lepidium campestre, Linn., was collected by R. G. Bechdolt along 

 roadsides south of Bethlehem.

109. Symphoncarpus racemosus, Michx., var pauciflorus 



Robbms, m New York State.— I have specimens of this plant which 

 I collected m July, 1S78, at the top of a bluff on the western shore 

 of Lake Champlam, near Port Henry, Essex Co., N. Y. Quite a 

 large patch was growing there, and its small leaves and few flow^ers 

 mark it as a good variety.
