 peculiar subaquatic form but with the characteristic leaf structure of this spec-

B. glareosum B. & S. On soil in a coniferous forest near Tolland. Differs 

 from B. salebrosum in being dioicous and in the large leaves with a longer, more 

 slender and twisted acumination. The leaves are also more plicate and rather 

 less serrate. In gross appearance this somewhat resembles Camptothecium lutes- 

 cens from which it differs in the more numerous and larger quadrate alar cells of 

 the more slenderly acuminate leaves. The Colorado specimens are darker than 

 is typical. They are the first American specimens that I have seen that I could 

 refer to this species. Those collected by Macoun and Brinkman are B. sale^ 

 brosum, to my mind.
