Septaquila Tasselweed

The Septaquila Tasselweed has become the first member of its genus to venture into fresh water. They have greatly reduced their stipe to the point it is nearly non-existent. The singular float has become the de facto stipe and sports many sets of fronds. Its holdfast has become more adept at holding it in place on both rocky and sandy substrate. To deal with low tide conditions it forms a powdery wax on its surfaces when they are exposed to air to guard against desiccation. They reproduce much the same as their ancestors, producing microscopic gametophytes which develop into macroscopic sporophytes. In the low competition of the rivers and wetlands they have developed to become perennial, becoming dormant during temperate winters and regrowing any damaged tissue come spring.
