A sheet of green
This is a very simple seaweed that reproduces itself by fragmentation, each fragment growing into a new plant. Two common kinds are found at Crane’s Beach:
Ulva lactuca, which is the broad green “leaf”; Ulva lanceolata, which is in thinner, more ribbon-like strips.
The Red Algae
Irish Moss (Chondrus crispus)
Flattened, branching fronds Purple in life, white when sun-bleached
Here is a very common tidal plant that has commercial value. It is called “Dulse” on the Boston markets, and a very delicious pudding is prepared from it (seamoss farine). Why not take some home and try it?
Polysiphonia (Polysiphonia, several species)
