Type locality. USA: Florida, “two miles (3.2 km) west of Cape Romano ...” ( Nutting 1900: 59)  .

Material examined. Fort Myers Beach, on stranded Idiellana pristis  , 01 March 2013, three colonies or colony fragments, up to 1 cm high, without gonophores, coll. D. Calder, ROMIZ B4399.

Remarks. Plumularia floridana Nutting, 1900  was originally described from the vicinity of Cape Romano, on the southwest coast of Florida. It is a relatively well-known species in warm-temperate to tropical waters of the western Atlantic, with an inshore range extending from southern Massachusetts ( Fraser 1944) to Brazil ( Oliveira et al. 2016). It has also been reported in offshore waters along the eastern United States on pelagic Sargassum  in the Gulf Stream ( Fraser 1944).

Hydroids of P. floridana  seem quite distinctive. Colonies are small (usually <2 cm high), with relatively large, nearly cylindrical hydrothecae that are free from the hydrocladia for 1/3 or more of their length. Even more distinctive is the gonosome, with gonothecae that are small, thin, filmy, and oval to nearly round. These structures collapse once the gonothecal contents are released.

While P. floridana  has been found in open ocean environments such as the tops of Challenger and Plantagenet banks off Bermuda ( Calder 2000), it has been reported most often from nearshore environments. In coastal South Carolina colonies are widespread across the state, occurring from euhaline waters (>30‰) to about the 25‰ iso- haline upestuary ( Calder 1976, 1983; Calder & Hester 1978). As for seasonality in the same region, active colonies were found from mid-March through early January, over a temperature range from 10–32° C (Calder 1990). Its reported bathymetric range extends from the surface, on pelagic Sargassum ( Fraser 1944)  , to a depth of at least 73 m (Calder 1997).

Plumularia floridana  is thought to be circumglobal in warm-temperate and tropical waters ( Ansín Agís et al. 2001; Calder 2013), although confirmation is needed. More information on the species is given in Migotto (1996), Calder (1997), and Ansín Agís et al. (2001).
