(From Strasburger.) it represents the undivided contents of a whole sporangium, such as may be seen in other Siphonales. The Siphonales and Siphonocladiales rcprotluce sexually ; but degrees of difference in size of the gametes are seen. The differentia- tion thus indicated must be held as distinct from, though parallel with that already described in the Brown Algae, and in the Ulothri- cales. In Acetabidaria the gametes are of equal size, and those produced from different sporangia, or from different plants fuse in.
