Evidence is adduced to show that CI. sessifolinm has not 

 been found east of the Coast Range, and that U. stellatiun ac- 

 tually crosses the continent as does U, racemosum. More fruit- 

 ing specimens are called for.

Proceedings of the Club. 



The regular meeting of the Club was held at Columbia Col- 

 lege, Dec. loth, the Vice-President in the chair and twenty-two 



persons present. 



An Amendment to the Constitution was adopted, making the 

 regular meetings of the Club twice a month. The announced 

 lecture of the evening ** Fungus Diseases of the Cranberry," by 

 Professor Byron D. Halsted was then dehvered. The substance 

 of his remarks was as follows : 



The minute, red galls upon the cranberry leaves, stems, flow- 

 ers and fruit, are caused by a unicellular fungus known as Syn- 

 chytrinnt Vaccinii, Th. It is probably at present confined to 

 the Marian Boq;, near Brown*s Mill, Burlington County, New 



Jersey. The following additional members of the Ericaceae are 

 hosts to this gall fungus: Rhododendron viscosum, Kalmia an- 

 giistifolia, Clethrii alnifolia, Cassandra calycnlata, Gaylussacia 

 resinosa and Gaultheria procumheiis, in all of which tiie fungus- 

 bearing cell of each gall is much alike, but in the galls them- 

 selves there is a wide variation upon the different hosts. These 

 plants are infested only when within reach of the bog water and 

 above the high tide or flood mark no galls are to be found. In 

 a portion of the bog, cut off by a railroad grade with no water- 

 way through it, there were no galls. The upper portion of the 

 bog is upon two streams which join near its middle.
