Bonnemaisonia hamifera (Marine Algae of Cape Cod, Massachusetts and Adjacent Islands)

Bonnemaisonia hamifera

Description ⁴

Gametangial phase much branched, to 20 cms in length. Branches spirally in pairs of unequal length. Some branches form reflexed hooks by which it attaches itself to other algae.

The tetrasporangial phase Trailliella is monosiphonous, irregularly branched and although only a few cms long is readily identified by the small colourless cell at the upper end, and set to the side, of each cell.

Distribution ⁵

British Isles: England, except on the east coast, Ireland, Scotland, Wales, Isle of Man and the Channel Islands. Europe: Mediterranean, Atlantic coasts of Spain and France, Netherlands (drift), Helgoland, Baltic Sea, Norway, the Faroes and Iceland. Atlantic coast of North America: Canada, Maine, New Hampshire, Massachusetts, Connecticut, Long Island and Virginia. Further afield: Canary Islands, South Africa and Japan.

Habitat ⁶

Gametangial phase usually sublittoral or occasionally low littoral. Tetrasporangial phase usually epiphytic in lower littoral and sublittoral to 8 m.
