The plants observed were of interest on account of the presence of the sexual organs. The 

 latter were first described by Hnber, and have very rarely been seen. The oogoma were filled 

 with oily material giving them a very refractive appearance, and when ready for expelling the 

 oosphere were almost globular in shape. The antheridia were not invariably terminal at the extre- 

 mities of the branches, bnt were occasionally developed from the side of a median cell of the 

 filament. Since examining the antheridia, we are inclined ta regard them as consisting of from 

 one to three cells, from each of which one or two 4-ciliated antherozoids are ultimately set free.
