porrifoli 



J. He also stated that 



Epilobinni palustrc 



different from that of any other species of the genus in having the 



w 



four grains produced in each mother cell, remahi united in a 

 quadrate mass and are only separated by prolonged teasing. The 

 individual grains are large, as they noticeably arc in the genus, 

 and the groups are therefore remarkably conspicuous. When 

 taken from the stigma they usually exhibit tubes proceeding one 

 from each of the four grahis. That the plant common and that 

 the quadrate pollen masses make fine objects for the microscope 

 are the excuses for mentioning the peculiarity not often met with 

 elsewhere. In this species it seems to be constant. In the ab- 

 sence of Prof. Halsted his communications were presented by the 



Secretary. 



or McBridc stated that he thought other species of 

 Epilobinin shared the same structure. 



A paper by Miss E. Porter — '* Notes on Spore Discharge of 

 Ascomycetes," was read by the Secretary. It contained observa-

 in the study of vegetable pathology.
