Malacochaete assimilis

Schoenoplectus californicus

Schoeneoplectus californicus is a species of sedge known by the common names California bulrush and giant bulrush. It is also sometimes called "tule", but the closely related Schoenoplectus acutus is the more correct owner of that name. It is a rhizomed water plant found in marshy areas from southern and western North America to South America and on Pacific islands including some of those in the Hawaiian and Cook chains. It has tall, thin, dark green stems which are usually triangular in cross-section and woolly, bristly tan or brown flowers in panicle inflorescences.

A notable subspecies is the Totora, Schoenoplectus californicus ssp. tatora. This is famous for making up the floating islands on which the Uros people of Lake Titicaca dwell, as well as occurring on isolated Easter Island in the Pacific.
